Purpose And Objectives Of Software Testing

Software Testing Purpose And Objectives

Software Testing has different goals .The major goals of Application testing are as follows:

Discovering problems which may get created by the programmer while developing the application.

Gaining assurance in and offering information about the standard.

To prevent problems.

To ensure that the end result meets the company and customer requirements.

To ensure that it satisfies the BRS that is Business Requirement Specification and SRS that is System Requirement Specifications.

To gain the assurance of the clients by giving them top quality products.

Software testing helps in completing the application program or item against company and customer requirements. It is very important to have good analyze protection to be able to evaluate the application program completely and then ensure it is sure that it’s performing well and as per the requirements.

While determining top quality protection top quality situations should be designed well with maximum possibilities of choosing the errors or bugs. The analyze situations should be extremely efficient. This objective can be measured by the variety of problems revealed per analyze situations. Higher the variety of the problems revealed the more beneficial are top quality situations.

Once the delivery is made to the end users or the clients they should be able to operate it without any complaints. To help accomplish this the tester should know as how the clients are going to use this item and accordingly they should write down top quality scenarios and design top quality situations. This will help a lot in fulfilling all the customer’s requirements.

Software testing makes sure that the tests being done properly and hence the product is ready for use. Good protection means that the testing has been done to cover the various areas like functionality of the program, compatibility of the program with the OS, hardware and different types of browsers, efficiency testing to evaluate the efficiency of the program and load testing for making sure that the product is reliable and should not crash or there should not be any blocking issues. It also decides that the program can be implemented easily to the machine and without any resistance. Hence the program is easy to install, learn and use.

Examining with a Purpose

Software tests performed to ensure that the completed program features according to the objectives defined by the requirements/specifications. The overall objective to not to find every program bug that prevails, but to locate situations that could adversely impact the customer, functionality and/or maintainability.

From the component stage to the program stage, this article describes a lot of of testing. Based on the reason for testing and the program requirements/specs, a combination of testing strategies is applied. One of the most neglected areas of tests regression testing and mistake resistant testing.

Definition of Testing Types

Functional Testing

Module testing confirms that each program device works as predicted according to the needs using a small part of possible feedback factors. At the program stage, testing confirms that the whole program features together according to the needs. Example:

Moving in real life factors as well as legitimate but uncommon factors.

Parametric Testing

At the component stage, testing confirms that each program device works as predicted according to the needs for the wide variety of legitimate feedback factors. Example:

Moving in each parameter at its lowest, highest possible and average principles, as well as passing in factors at least and highest possible principles at the same time.

Fault Tolerant Testing

Module testing confirms that each program device does not perform in a bad or surprising way for unlawful or out-of-range feedback factors. At the program stage, testing confirms that the whole program features together in a elegant way according to the needs when presented with surprising and/or out-of-range principles. Example:

Moving zero suggestions and the wide variety of possible principles for each parameter.

Integration Testing

Integration tests an additional step that is used when different sub-systems are being developed at the same time by independent designers. It confirms that the factors passed between sub-systems are being managed correctly. Example:

Moving zero suggestions and the wide variety of possible principles for each parameter.

Regression Testing

Regression tests retesting sub-systems/modules/units to guarantee that variations to one sub-system/module/unit does not cause surprising results in another sub-system/module/unit. This is also known as swell effect testing.

Integration Testing Overview

What is Integration Testing?

Upon finishing device testing, the models or segments are to be incorporated which gives raise to integration testing. The objective of integration testing is to ensure the effective, efficiency, and stability between the segments that are incorporated.

Integration Strategies:

Big-Bang Integration

Top Down Integration

Base Up Integration

Multiple Integration

The objective of integration testing is to ensure effective, efficiency, and stability requirements placed on significant style products. These “design items“, i.e., assemblages (or groups of units), are worked out through their connections using black box testing, success and mistake situations being simulated via appropriate parameter and information information. Simulated use of distributed information areas and inter-process connections is examined and personal subsystems are worked out through their feedback user interface. Analyze situations are designed to evaluate whether all the ingredients within assemblages communicate properly, for example across process calls or process activations, and this is done after testing personal segments, i.e., device testing. The overall idea is a “building block” technique, in which confirmed assemblages are added to a confirmed base which is then used to support the integration testing of further assemblages.

Software Integration Assessments conducted according to the Software Development Life Cycle (SDLC) after element and effective tests. The cross-dependencies for software integration testing are: agenda for integration testing, technique and selection of the tools used for integration, determine the cyclomatical complexness of the application and software structure, reusability of segments and life-cycle / versioning management.

Some different types of integration testing are big hit, top-down, and bottom-up, combined (sandwich) and dangerous – toughest. Other Integration Patterns are: Backbone Integration, Layer Integration, Part Integration, Client/Server Integration, Distributed Services Integration and High-frequency Integration.

Big Bang

In the process, most of the developed segments are combined together to form a complete software program or main issue with the program and then used for integration testing. The Big Bang method is very effective for not wasting time in the integration testing process. However, if quality situations and their results are not documented properly, the entire integration process will be more complex and may prevent the testing team from accomplishing with regards to integration testing.

A kind of Big Bang Integration testing is called Utilization Design testing. Utilization Design testing can be used in both software and components integration testing. The basis behind this kind of integration testing is to run user-like workloads in incorporated user-like surroundings. In doing the testing in this manner, the atmosphere is proofed, while the personal elements are proofed ultimately through their use. Utilization Design testing takes an positive way to testing, because it desires to have few issues with the personal elements. The process depends on the element designers to do the separated device testing for their product. The purpose of the technique is to avoid replacing the testing done by the designers, and instead flesh-out issues due to the connections of the ingredients in the atmosphere. For integration testing, Utilization Design testing can be more effective and provides better test coverage than traditional targeted effective integration testing. To be more effective and precise, care must be used in interpreting the user-like workloads for creating genuine circumstances in training the atmosphere. This gives confidence that the incorporated atmosphere will work as expected for the focus on customers.

Top Down Tests a way of integrated testing where the top incorporated segments are examined and the division of the component is examined phase by phase until the end of the related component.

Sandwich Tests an way of merge top down examining with base up examining.

The main advantage of the Bottom-Up strategy is that bugs are more easily found. With Top-Down, it is more readily found a missing division link.

Risky – toughest incorporation testing is a technique where the incorporation testing is performed starting with the dangerous and toughest software component first.

What is cost of quality in software?

Cost Of Poor Quality (COPQ): The charges associated with provision of inadequate quality item or facilities is called as cost of quality. There are four classes: inner failure expenses (costs associated with problems found before the client gets the item or service), exterior failure expenses (costs associated with problems found after the client gets the item or service), evaluation expenses (costs suffered to find the degree of conformance to high quality requirements) and protection expenses (costs suffered to keep failure and evaluation expenses to a minimum).

Cost of high quality is a methodology that allows a company to find the extent to which its resources are used for actions that avoid inadequate, that praise the company’s items or facilities, and that result from exterior and inner failures. Having such information allows a company to find the potential benefits to be gained by implementing process developments.

Quality-related actions such as quality of planning that incur expenses may be divided into protection expenses, evaluation expenses, and exterior and inner failure expenses.

Prevention costs

Prevention price is suffered to avoid or avoid high quality problems. These price is associated with the design and style, implementation, and upkeep of the standard management program. They are planned and suffered before actual operation, and they could include:

Products or solutions requirements—establishment of requirements for inbound components, procedures, completed items, and services

Quality planning—creation of plans for high quality, reliability, functions, production, and inspection

Quality assurance—creation and upkeep of the standard system

Training—development, preparation, and upkeep of programs

Appraisal costs

Appraisal price is associated with measuring and monitoring actions associated with high quality. These price is associated with the suppliers’ and customers’ evaluation of purchased components, procedures, items and facilties to ensure that they conform to requirements. They could include:

Verification—checking of inbound content, process setup, as well as against agreed specifications

Quality audits—confirmation that the standard program is functioning correctly

Supplier rating—assessment and approval of suppliers of merchandise and services

Internal failure costs

Internal failing price is suffered to treat problems found before the item or support is delivered to the client. These expenses happen when the results of perform are not able to achieve style high quality requirements and are recognized before they are transferred to the client. They could include:

Waste—performance of unnecessary perform or holding of stock as a result of mistakes, inadequate company, or communication

Scrap—defective item or content that cannot be repaired, used, or sold

Rework or rectification—correction of faulty content or errors

Failure analysis—activity required to establish the causes of inner item or support failure

External failure costs

External failure price is suffered to treat problems found by customers. These expenses happen when items or facilties that are not able to achieve style high quality requirements are not recognized until after transfer to the client. They could include:

Repairs and servicing—of both returned items and those in the field

Warranty claims—failed items that are replaced or solutions that are re-performed under a guarantee

Complaints—all perform and charges associated with managing and servicing customers’ complaints

Returns—handling and investigation of rejected or recalled items, including transport costs

Cost of high quality and organizational objectives

The expenses of doing an outstanding job, conducting high quality developments, and achieving goals must be carefully managed so that the long-term effect of high quality on the company is a desirable one.

These expenses must be a true way of measuring the standard effort, and they are best determined from an research of the expenses of high quality. Such an research provides a method of assessing the effectiveness of the management of high quality and a means of determining problem areas, opportunities, benefits, and action priorities.

Cost of high quality is also an important interaction device. Philip Crosby demonstrated what a powerful device it could be to raise awareness of the importance of high quality. He referred to the evaluate as the “price of nonconformance” and argued that companies choose to pay for inadequate.

Many companies will have true quality-related expenses as high as 15 to 20 % of sales revenue, some going as high as 40 % of total functions. A general principle is that amounted to inadequate in a thriving company will be about 10 to Fifteen % of functions. Effective high quality improvement programs can reduce this substantially, thus making a direct contribution to profits.

Software Testing- Quality Control And Quality Assurance

What is Testing?

Testing is the procedure of analyzing an activity or its component(s) with the purpose to find whether it meets the specified specifications or not. In simple terms, examining is performing a program in order to recognize any holes, mistakes,or losing specifications with respect to the real specifications.

Who does Testing?

It relies on the procedure and the associated stakeholders of the project(s). In the IT market, huge organizations have a group with obligations to assess the designed application in the perspective of the given specifications. Moreover, designers also perform examining which is known as Device Testing. Generally, the following experts are engaged in examining a program within their specific capacities:

  1. Software Tester

  2. Software Developer

  3. Project Lead/Manager

  4. End User

What is Quality?

Quality is meeting the requirement, expectation and needs of the client being free from problems, lacks and substantial variants. There are requirements needs to follow to satisfy the client requirements and that is the job of the QA engineer.

What is Assurance?

Assurance is provided by organization management, it means giving a positive declaration on an item which obtains confidence for the outcome. It gives a security that the item will work without any glitches as per the expectations or requests.

Quality Guarantee is known as QA and concentrates on preventing problem. Top quality Guarantee helps to ensure that particularly, techniques and operations focus on the projects are implemented properly. Top quality assurance actions observe and confirm that the procedures used to manage and create the deliverables have been followed and are operative and that is the job of the QA engineer.

Quality Guarantee is a proactive procedure and is Prevention in characteristics. It identifies flaws in the procedure. Top quality Guarantee has to complete before Top quality Management.

What is Control?

Control is to test or confirm actual results by comparing it with the described requirements.

What is Top quality Control?

Quality Management is known as QC and concentrates on identifying problem. QC helps to ensure that particularly, techniques and operations are created in the venture are following properly. QC actions notee and confirm that the venture deliverables meet the described quality requirements.

Quality Management is a reactive procedure and is detection in characteristics.. It identifies the problems. Software quality has to complete after quality assurance.

Distinction between top quality guarantee and top quality control

Many people think QA and QC are same and exchangeable but this is not real. Both are firmly connected and sometimes it is hard to recognize the variations. Reality is both are relevant to each other but they are different in roots. QA and QC both are part of Quality Management however QA is concentrating on avoiding problem while QC is concentrating on determining the problem.

Audit and Inspection

Audit : It is a methodical procedure to determine how the actual examining procedure is performed within an organization or a team. Generally, it is an independent examination of procedures engaged during the examining of a application package. As per IEEE, it is a review of recorded procedures that organizations implement and adhere to. Types of audit consist of Legal Conformity Review, Internal Review, and System Review.

Inspection : It is an official strategy that includes official or casual technical reviews of any doll by determining any mistake or gap. As per IEEE94, examination is an official assessment strategy in which application requirements, designs, or codes are analyzed in detail by a person or a group other than the author to identify mistakes, offenses of growth requirements, and other issues.

Formal examination meetings occasionally includes the following processes: Planning, Summary Preparation, Inspection Meeting, Remodel, and Follow-up.

Testing and Debugging

Testing : It requires determining bug/error/defect in an application package without solving it. Normally professionals with a quality assurance background are concerned in insects identification. Tests performed in the examining stage.

Debugging : It requires determining, identifying, and solving the problems/bugs. Designers who rule the application conduct debugging upon experiencing an mistake in the rule. Debugging is a part of White Box Testing or Device Testing. Debugging can performed in the growth stage while conducting Device Testing or gradually while solving the reported insects.

What is the difference between Manual and Automation Testing?

What is the difference between Manual and Automation Testing?

Application assessments a huge domain, but it can be generally classified into two areas: guide examining and computerized examining.

Both guide and computerized examining offer advantages and drawbacks. It’s worthwhile to learn the difference, and when to use one or the other for best outcomes.

In guide examining (as the name suggests), analyze situations are implemented personally (by a person, that is) without any support from resources or programs. But with computerized examining, analyze situations are implemented with the assistance of resources, programs, and software.

Software Testing is part of any effective software venture. The kind of examining (manual or automated) relies on various aspects, such as venture requirements, budget, schedule, expertise, and relevance. Three vital aspects of any venture are of course time, price, and top quality – the objective of any effective venture is to reduce the price and time required to complete it efficiently while keeping top quality outcome. When it comes to examining, one kind may accomplish this objective better than the other.

When Should I Use Manual vs. Automated testing?

In brief, guide assessments best suited to the following areas/scenarios:

Exploratory Testing: This kind of examining requires the tester’s knowledge, experience, analytical/logical abilities, creativeness, and instinct. Quality is recognized here by badly written requirements certification, and/or a brief time period for performance. We need a persons abilities to operate the examining procedure in this situation.

Functionality Testing: This is an area in which you need to measure how user-friendly, efficient, or convenient the application or product is for potential customers. Here, individual statement is the most essential aspect, so a guide strategy is more suitable.

Ad-hoc Testing: In this situation, there is no specific strategy. It is a totally unexpected method of examining where the understanding of the specialist is the only essential aspect.

Manual Application Testing

Manual Application Testing is the operation of going in and operating each individual system or sequence of projects and evaluating the outcomes to the objectives, to find the problems in this method. Basically, guide assessments using this method as the consumer would under all possible circumstances, and making sure all of the features act properly.

The procedure can be rather boring to choose every setting within a system. For instance, you might be examining international software for 300 nations, so you need to make sure each of the nations adjusts with the appropriate Forex. To personally analyze this, you would decide on a country and look to see that it has the appropriate Forex. But if a system might only have a few options, it would be much more controllable to personally run through the choices and the effects of each selection.

Usually, when you’re employed by your small business with few money, this is going to be your best option. A big advantage of guide assessments the ability to see actual customer issues. Compared with a software, when creating software, going through personally allows you to see insects that a genuine customer could face.

Automated Application Testing

Automated software examining uses computerized resources to run assessments based on methods to compare the creating program’s expected outcomes with the actual outcomes. If the effects are arranged, your system is operating properly and you are most likely bug free. If the two don’t arrange, you have to take another look at your code and modify it and continue to run assessments until the effects arrange.

According to David Overbought, a mature SDET lead at Microsoft, “It only seems sensible to use computerized examining resources when the costs of getting the tool and building and also the assessments is less than the performance obtained from the effort.”

Automated assessments best to use when you’re focusing on a large venture, and there are many system customers. The biggest advantages of computerized examining are its comparative explosiveness and performance. Once your initial analyze is set up, it’s easy to do it again assessments, consistently fill out the same information and everything is done for you instantly.

Software Testing Life Cycle Process

What is a Software Lifecycle?

Lifecycle in simple term signifies succession of changes from one type to other type. These changes can happen to any concrete or intangible things. Every enterprise has a lifecycle from its beginning to end/ death.

In a similar fashion, software is also a business. Just like creating software includes a series of actions, examining also has actions which should be implemented in a certain series.

This trend of performing the examining activities in a thorough and organized way is called examining life-cycle.

Software Test Life Cycle

Like SDLC, STLC has set stages which is described in structure below:

1. TEST PLANNING – Preparing the test strategy & planning
2. TEST DEVELOPMENT – Creating the testing environment
3. TEST EXECUTION – Writing the test cases/Creating & Executing the Test Script
4. RESULT ANALYSIS – Analysis result and Bug report
5. BUG TRACKING –Look for Bugs and software errors
6. REPORTING – Gathering reports from users
What is Software Testing Lifestyle Pattern (STLC)

Software Testing Lifestyle Pattern represents a examining procedure which has specific actions to be implemented in a certain series to make sure that the quality objectives have been met. In STLC procedure, each action is completed in a structured and methodical way. Each stage has different objectives and deliverable’s and test planning.

Below are the stages of STLC:

1. Specifications phase
2. Preparing Phase
3. Research phase
4. Style Phase
5. Execution Phase
6. Performance Phase
7. Summary Phase
8. Closing Phase

#1. Specification Phase:

During this stage of STLC, evaluate and study the needs. Have brain storming classes with other groups and try to find out whether the needs are testable or not. This stage helps to recognize the opportunity of the examining. If any feature is not testable, connect it during this stage so that the minimization strategy can be planned.

#2. Preparing Phase:

In practical circumstances, Analyze planning is the first step of the examining process. In this stage we recognize the activities and resources which would help to meet the examining goals. During planning we also try to recognize the analytics, the method of collecting and monitoring those analytics.

#3. Research Phase:

This STLC stage describes “WHAT” to be tested. We basically recognize quality circumstances through the needs papers, product threats and other test basis. The test situation should be traceable back to the importance.

#4. Style Phase:

This stage describes “HOW” to evaluate. This stage requires the following tasks:

Details quality situation. Break down quality circumstances into several sub circumstances to increase protection.
– Identify and get quality data
– Identify and set up quality environment.
– Make the importance traceability metrics
– Make quality protection analytics.

#5. Execution Phase:

The major task in this STLC stage is of development of the specific test situations. Focus on quality situations also recognize which test situation will become part of the regression package. Before completing quality situation, It is essential to carry out evaluation to ensure the correctness of quality situations. Also don’t ignore to take the sign off of quality situations before real execution starts. If your venture includes automated, recognize the applicant test situations for automated and continue for scripting quality situations. Don’t ignore to evaluate them!

#6. Performance Phase:

As the name indicates, this is the Software Testing Life Pattern stage where the particular execution occurs. But before you start your execution, make sure that your entry requirements is met. Perform quality situations, log problems in situation of any difference. At the same time fill your tractability analytic to track your progress.

#7. Summary Phase:

This STLC stage focuses on the quit requirements and confirming. Based on your venture and stakeholders choice, you can decide on confirming whether you want to deliver out a regular overview of every week evaluation etc. There are different types of reviews ( DSR – Daily Sales Report, WSR – Weekly Sales reports) which you can deliver, but the essential point is, the content of evaluation changes and depends upon whom you are delivering your reviews.

#8. Closing Phase:

Tasks for the closure activities are the following:

Examine for the finalization of quality. Whether all quality cases are implemented or reduced purposely. Examine there are no intensity 1 problems started out.
– Do training learned meeting and create training learned papers.( Consist of what went well, where are the opportunity of developments and what can be improved)

Software Development Life Cycle Overview

Software Development Life Cycle Overview

Software industries use SDLC process to design, develop and test high quality software. The aim of SDLC is to produce a high quality software that meets customer expectations, reaches completion within times and cost effective.

  • SDLC is the acronym of Software Development Life Cycle.
  • It is also called as Software development process.
  • The SDLC is a framework defining tasks performed at each step in the software development process.
  • ISO/IEC 12207 is an international standard for software life-cycle processes. It aims to define all the tasks necessary for developing and maintaining software.

SDLC consists of a detailed plan describing how to develop, maintain, replace and modify specific software. The life cycle defines a methodology for improving the quality of software and the overall development process.

Here is the graphical representation of the various stages of a SDLC

Stages of SDLC:

Stage 1: Requirement Gathering

Requirement analysis and gathering is the most important and fundamental stage in SDLC. It is performed based on inputs from the customer, the sales department, market surveys and domain experts in the industry. This forms the base for planning a project approach. This phase also includes planning for quality assurance necessities and finding of risks associated within the project.

Stage 2: Feasibility Study

After doing with the requirement analysis, the next step is to clearly define and document the raw plan of software process and get them approved from the customer. This is done through SRS , Software Requirement Specification document.

Stage 3: Software Design

The next step is to materialize whole knowledge of requirements and analysis and design the software product. Based on the requirements specified in SRS, usually more than one design mode of approach for the product is proposed and documented in a Design Document Specification(DDS). After reviewing the DDS, the best design approach is selected  the product.

Stage 4: Coding

This is called programming phase and the programming code is generated as per the DDS . If a detailed and organized design is performed , code generation can be accomplished without much hassle.

Developers follows the coding guidelines defined by their organization and use programming tools like compilers, interpreters, debuggers etc to generate the code. Different high level programming languages such as C, C++, Pascal, Java, and PHP are used for coding and these languages are chosen as per what the requirement is for the software being developed.

Stage 5: Testing

Software Testing is a sub set of all the stages as in the modern SDLC models. Initially peer testing is done and then a thorough testing is conducted by testing experts at various coding levels such as module testing, program testing, product testing, in-house testing and testing the product at user’s end. Early discovery of errors and their remedy is the key to reliable software.

Stage 6: Deployment and Maintenance

After the product is tested and ready to be deployed it is finally released in the appropriate market. Sometime the product deployment happens in stages as per the organizations. The product is first released in a limited segment and tested in the real business environment (I.e UAT).

Then based on the feedback, the product may be released as it is created or with suggestions for enhancements in the targeting market . After the product is released in the market, its has to be maintained for the existing customer base.

SDLC Models

Various software development life cycle models are designed which are followed during software development . The models are also referred as “Software Development Process Models”. And each process model follows a series of unique steps unique in order to ensure success.

Following are the most important and popular SDLC models followed in the industry:

  • Waterfall Model
  • Iterative Model
  • Spiral Model
  • V-Model
  • Big Bang Model

The other similar methodologies are Agile Model, RAD Model, Rapid Application Development and Prototyping Models.

WebDriver And It’s Comparison With Selenium RC

WebDriver And It’s Comparison With Selenium RC

Web Driver is an automation tool of Software Testing, that aims to execute tests against different browsers.

Web Driver enables the usage of a programming languages in creating test scripts; which is not possible in Selenium IDE. It enables conditional operations like if-then-else or switch-case and also looping like do-while.

software-testing

The programming languages supported by Web-Driver are:

  • Java
  • .Net
  • PHP
  • Python
  • Perl
  • Ruby

Web Driver Vs Selenium RC

Web Driver succeeded Selenium Remote Control. Features common in both Web Driver and Selenium RC are:

  • Both enables usage of programming language in designing test scripts.
  • Both allows to run tests against different browsers.

So what are the differences?

The architecture

Selenium Remote Control (RC) has a complicated architecture. It allows to write automated web application UI tests in any programming language against any HTTP website using mainstream JavaScript-enabled browser. RC Server fetches the next instruction from test scripts to repeat the whole cycle. Selenium RC is slower since it uses a JavaScript program called Selenium Core which is the one that directly controls the browser.

Web Driver’s architecture is simpler than Selenium RC’s. It controls the browser from the OS level And all needed are programming language’s IDE (which contains Selenium commands) and a browser. Web Driver is also faster than Selenium RC since it speaks directly to the browser.

Web Driver interacts with page elements in a more realistic way. For example, if there is a disabled text box on a page that is being tested, Web Driver cannot enter any value in it.

Selenium Core could access disabled elements.

API differences

Selenium RC’s API though mature,contains redundancies and often perplexing commands. For example, most of the time, testers are confused whether to use type or type Keys. What makes matter worse is that different browsers interpret each of these commands in different ways.

Web Driver’s API is simpler than Selenium RC’s. It has no redundancy and not perplexing.

The browser support

Web Driver can support the headless HTML Unit browser. It is termed “headless” because it is an invisible browser – it is GUI-less.

It is a very fast browser because no time is spent in waiting for page elements to load. This accelerates test execution cycles. Since it is invisible to the user, it can only be controlled through automated means.

Selenium RC cannot support the headless HTML Unit browser. It needs a real, visible browser to operate on.

Limitations of Web Driver

Web Driver Cannot support new browsers; since Web Driver operates on the OS level and different browsers communicate with the OS in different ways. If a new browser comes out, it may have a different process of communicating with the OS as compared to other browsers. So, the Web Driver team requires some time to figure that new process before they can implement it on the next Web Driver release.
Selenium RC Has Built-In Test Result Generator.

Selenium RC automatically generates an HTML file of test results whose format was Pre-Set by RC itself.

Web Driver has no built-in command that automatically generates a Test Results File. One has to rely on IDE’s output window, or design the report oneself using the capabilities of programming language and store it as text, HTML, etc.

Summary:

Selenium-Web Driver makes direct calls to the browser using each browser’s native support for automation.

Selenium-RC worked the same way for each supported browser. It ‘injected’ JavaScript functions into the browser when the browser was loaded and then used its JavaScript to drive the AUT within the browser.

Web Driver does not use this technique. Again, it drives the browser directly using the browser’s built in support for automation.

There are some reasons though to use the Selenium-Server with Selenium-Web Driver.

  • If you are using Selenium-Grid to distribute your tests over multiple machines or virtual machines (VMs).

  • If you want to connect to a remote machine that has a particular browser version that is not on your current machine.

  • If you are not using the Java bindings and would like to use HTML Unit Driver.

    What are the different types of Testing?

What are the different types of Testing?

This section explains the different types of examining that may be used to analyze a program package during SDLC.

Manual Testing

Manual Testing examining contains examining a program package personally, i.e., without using any computerized device or any program. In this type, the specialist takes over the role of an end-user and assessments the program to recognize any surprising behavior or bug. There are different stages for guide examining such as unit examining, incorporation examining, system examining, and customer approval examining.

Testers use analyze plans, analyze cases, or analyze circumstances to analyze a program package to ensure the completeness of examining. Manual examining comes with exploratory examining, as evaluators discover the program to recognize mistakes in it.

Automation Testing

Automation Testing examining, which is also known as Test Automated, is when the specialist creates programs and uses another program to analyze the product. This technique involves automation of a guide procedure. Automated Tests used to re-run quality circumstances that were performed personally, quickly, and continuously.

Apart from regression examining, automation examining is also used to analyze the program from fill, efficiency, and stress perspective. It improves quality coverage, improves precision, and helps you to save money in comparison to guide examining.

What is Automate?

It is not possible to improve everything in a program package. Other places at which a customer can make dealings such as the sign in form or signing up forms, any area where huge amount of customers can access the program at once should be computerized.

Furthermore, all GUI items, relationships with data source, field validations, etc. can be efficiently tested by automating the guide procedure.

When to Automate?

Test Automated should be used by considering the following aspects of a software:

Large and critical projects

Tasks that require examining the same places frequently

Requirements not changing frequently

Obtaining the program for fill as well as with many virtual users

Constant program with respect to guide Testing

Accessibility to time

How to Automate?

Automation is done by using a helpful computer language like VB scripting and a computerized program. There are many resources available that can be used to write automation programs. Before referring to the resources, let us get the procedure that can be used to improve the examining process:

  1. Determining places within a program package for automation

  2. Selection of appropriate device for analyze automation

  3. Writing analyze scripts

  4. Development of analyze suits

  5. Performance of scripts

  6. Create result reports

  7. Identify any potential bug or efficiency issues

Software Testing Tools

The following resources can be used for automation testing:

HP Quick Test Professional

Selenium

IBM Logical Efficient Tester

SilkTest

TestComplete

Testing Anywhere

WinRunner

LoadRunner

Visual Studio room Test Professional

WATIR

What is Software Testing?

What is Software Testing?

Testing is the procedure of analyzing a program or its component(s) with the purpose to find whether it satisfies the specified requirements or not. In simple words, tests performing a program in order to recognize any holes, mistakes, or losing requirements in contrary to the actual requirements.

According to ANSI/IEEE 1059 standard, testing can be described as – A procedure for examining a application package product to recognize the variations between current and required conditions (that is defects/errors/bugs) and to look at the features of the application product.
