Software Testing: How To Generate Test Data

Test data forms an important aspect of software testing. It can be called as the heart or the soul of software testing. This is because the testing process consumes and produces test data at almost each stage. A software testing course mostly has a module dedicated to test data. In this article, we would like to introduce you to test data, and how is it generated.

Data utilized as a part of testing depicts the underlying conditions for a test and speaks to the medium through which the tester impacts the product. It is a critical part of functional testing.

What do we mean by test data? It’s Importance:

Test data is in fact the input fed to a software program. It is nothing but data that effects or is influenced by the execution of a particular module. A few data might be utilized for positive testing, usually to confirm that a given set of input to a given function creates an expected outcome. Other data might be utilized for negative testing to test the capacity of the program to deal with irregular, extraordinary, remarkable, or unexpected input. Ineffectively designed testing data may not test all conceivable test situations which will hamper the nature of the software.

Test data generation and the need to keep it ready prior to test execution:

Ideally, test data ought to be created before you start test execution since it is hard to perform test data management. Since in many testing conditions, generation of test data requires numerous pre-strides or test environment arrangements which is extremely tedious. Likewise if test data generation is done while you are in test execution stage, you may surpass your testing deadline.

Contingent upon your testing environment, you may need to generate Test Data (Most of the circumstances) or at-least distinguish a reasonable test data for your test cases (is the test information is as of now made).

Commonly, test data is generated in-association with the test case it is expected to be utilized for.

Test Data can be Generated –

-Manually.

-Mass duplicate of data from generation to testing environment.

– Mass duplicate of test data from legacy client frameworks.

– Automated Test Data Generation Tools.

Test data generation using automation:

Keeping in mind the end goal to produce different sets of data, one can utilize an extent of automated test data producing tools. The following are a few cases of such tools:

Test Data Generator from GSApps can be utilized for producing clever data in any database or text file. It empowers users to:

  • Finish application testing by expanding a database with significant data.

  • Generating industry-particular data that can be utilized for a demo.

  • Ensure data privacy protection by making a clone of the current data and veiling confidential values.

  • Quicken the development cycle by disentangling testing and prototyping

Test Data generator by DTM, is a completely adaptable utility that creates data, tables (views, techniques and so forth) for database testing (QA testing, performance testing, load testing or usability testing) purposes.

Datatect is a SQL data generator from Banner Software, creates an assortment of realistic test data in ASCII level documents or specifically produces test information for RDBMS including Oracle, Sybase, SQL Server, and Informi.

All in all, all properly composed testing data permits you to recognize and rectify genuine flaws in functionality. Decision of test data chose must be reexamined in each phase of a multi-stage product development cycle. Along these lines, dependably watch out for it.

If you are interested for a career in the field of software testing, a software institute in Pune, would be an ideal place to get trained for the same.

Testing Tools and Their Classification

Today, we will learn about the various software testing tools available, and their classification. Software testing classes in Pune conducted by software testing institute in Pune can help you learn these tools in greater detail.

It is not required to have a one on one relationship between a kind of tool portrayed here and a tool offered by a business tool vendor or an open-source tool. A few tools play out a particular and constrained function (some of the time called a ‘point solution’), however a large number of the business tools offer help for a wide range of functions. For instance a ‘test mangement’ tool may offer help for overseeing testing (progress tracking), configuration administration of testware, incident administration, and requirements analysis and traceability. Correspondingly, another tool may give both coverage estimation and test design support.

There are couple of things that individuals are great at in contrast with the PCs. For instance, when you see your companion in a startling spot, similar to a shopping center, you can instantly perceive their face. This is on account that individuals are great at pattern identification, yet it is difficult to develop a software that can perceive a face. Then again there are things that computers can carry out more rapidly and effectively than individuals can do. For instance, addition of 20 three-digit numbers instantly. This is difficult for the vast majority to do, there are chances that you commit a few errors regardless of the possibility that the numbers are jotted down. A computer does this precisely and rapidly. Consider another case, if individuals are made a request to do the very same work again and again, it will be repetitive and they soon get exhausted and after that begin committing errors.

In this way, the thought is to utilize computers to do things that they are better at. Tool support is extremely helpful for repetitive tasks – the computer doesn’t get exhausted and will have the capacity to precisely repeat what was done before and that too with no slip-ups. Since the tools will be quick, this can make those tasks substantially more productive and more relying.

Taking after are the classifications of various sorts of testing tools as per the test procedure exercises. The “(D)” denoted after the sorts of tools demonstrates that these tools are for the most part utilized by the developers. The different sorts of test tools as indicated by the test process exercises are:

1.Test management tool support:

– Test management tools

– Requirements management tools

-Incident management tools

– Configuration management tools

2. Static testing tool support:

– Review process support tools

– Static analysis tools (D)

– Modelling tools (D)

3. Test specification tool support:

– Test design tools

– Test data preparation tools

4. Test execution and logging tool support:

– Test execution tools

– Test harness/ Unit test framework tools (D)

– Test comparators

– Coverage measurement tools (D)

– Security tools

5. Performance and monitoring tool support:

– Dynamic analysis tools (D)

– Performance testing, Load testing and stress-testing tools

– Monitoring tools

An tool that measures some part of software may have couple of sudden side effects additionally on that software. Like, for instance, a tool that records timings for performance testing requirements to communicate closely with that application keeping in mind the end goal to gauge it. A performance tool will set a start time and a stop time for a given exchange with a specific end goal to quantify the reaction time. However, by taking that measurement, that is putting away the time at those two focuses, could really make the entire task take marginally longer than it would do if the tool was not measuring the reaction time. Obviously, the additional time is little, however it is still there. This impact is known as the ‘probe effect’.

Benefits And Risks Involved In Using Testing Tools

A software testing institute in Pune , is the best place to learn testing related tools. A number of tools are taught in a software testing course in Pune. In this article, we are going to focus on the benefits and risk factors related to the testing tools.

One might think that the use of testing tools has only advantages. In spite of the fact that there are many benefits that can be accomplished by making use of tools to bolster testing related tasks, yet there are likewise many risks that are connected with it, when tools are pressed into service for testing.

Let’s see the benefits and risks involved, one after the other.

Benefits or advantages of testing tools:

1. Helpful in case of repetitive tasks :

Repetitive work becomes exceptionally exhausting in the event that it is done manually. Individuals tend to commit mistakes while doing tasks again and again. Cases of this kind of monotonous work incorporate regression testing, inputing similar test data over and over again (is possible by a test execution tool), checking with respect to coding standards (which should be possible by a static analysis tool) or creation of a particular test database (which should be possible by a test data preparation tool).

2. Consistency and repeatability factors :

Individuals have propensity to do a similar task in a somewhat different manner notwithstanding when they think they are repeating it precisely. A tool will precisely recreate what it did some time in the past, so every time it is run the outcome is reliable and consistent.

3. Easy access to information on testing or the tests :

Data introduced visually is much less demanding for the human mind to comprehend and decipher. For instance, a chart or a graph is a superior approach to portray data than a long rundown of numbers – this is the reason why graphs and charts in spreadsheets are so helpful. Specially designed tools give these features directly for the data they process.

Now, speaking about the risks involved, these include of the following:

4.Over expectations from the tool :

Unreasonable expectations might be one of the most likely risks, concerned with tools. The tools are nothing but a software and we as a whole realize that there are numerous issues connected with any sort of software. It is essential to have clear and practical goals for what the tools can do on a realistic basis.

5. Tendency to ignore factors like budget, time and efforts before the introduction of a tool:

Implementing something new into an organization is not a smooth sail. When you buy a tool, you need to have various individuals having the capacity to utilize the tool in a way that will be helpful. There will be some specialized issues to overcome, however there will likewise be resistance from other individuals – both should be taken care of in a manner that the tool will be a huge success.

6. Over dependence on the tool :

Since there are many advantages that can be picked up by utilizing tools to bolster testing like bringing down of the redundant tasks, more noteworthy consistency and repeatability, and so on, individuals began to rely on the tools a considerable measure. Yet, the tools are only a software they can do just what they have been intended to do (a decent quality tool can), however they can’t do everything. A tool can help, yet it can’t replace the knowledge required to know how best to utilize it, and how to assess present and future deployments of the tool. For instance, a test execution tool does not trade the requirement for a good test design and ought not be utilized for each test – a few tests are still better executed manually. A test that needs a long duration to automate and won’t be run regularly, is better done in a manual manner.

Software testing classes in Pune, can help you learn manual and automation testing, that includes various tools.

Why Is Usability Testing A Critical Part of Software Testing ?

Usability testing is aimed at taking into consideration the end user’s perspective. Usability testing is covered as a part of a software testing course conducted by a software institute in Pune.

Usability testing is a wide area in software testing and it requires genuinely high level of knowledge of this field alongside a creative thinking ability. Individuals taking part in the usability testing are required to have aptitudes like persistence, capacity to listen to the advices, openness to welcome different ideas, and the most critical of them all is that they ought to have great perception abilities to spot and resolve the issues or problems.

In case of usability testing, fundamentally the testers tests the simplicity with which the UIs can be utilized. It tests that whether the application or the software developed is easy to use or not.

Usability testing has the following benefits with respect to the customer or the end user :

  • Ensuring that the software is easy to use.

  • Ensuring the delivery of a quality software.

  • Easy acceptance of the software on the part of the users.

  • The learning curve is reduced in case of the new users.

Usability testing is a black box testing technique. Usability testing likewise uncovers whether users feel great with your application or website as per diverse parameters – the flow, navigation and design, content and speed – particularly in contrast with earlier or comparative applications.

Usability testing tests the accompanying elements of the software product.

— How simple it is to utilize the software.

— How simple it is to learn the software.

— How helpful is the software to the end users.

Usability testing advantages :

  • Usability testing can help in finding potential bugs and potholes in the framework which for the most part are not obvious to developers and even escape the other types of testing.

  • On the off chance that legitimate resources (experienced and innovative testers) are utilized, usability testing can help in settling every one of the issues that the user may confront even before the software is at long last released to the user. This may bring about better execution and a standard software.

  • Usability testing can be exceptionally economical if planned well, yet very viable and helpful.

  • Usability testing can be changed to cover numerous different types of testing, e.g. functional testing, system integration testing, unit testing, smoke testing and so on.

The five components of usability testing are as follows :

  1. Ability to learn: How simple is it for the users to achieve essential tasks the first time when they see the design?

  2. Efficiency: How quick can experienced users complete the tasks?

  3. Memorability: When users come back to the design after a time of not utilizing it, does the user recall enough to utilize it viably whenever, or does the user need to begin once again learning everything?

  1. Errors: What number of errors do users commit, how serious are these blunders and how effectively would they be able to recuperate from the blunders?

  2. Satisfaction: How much does the end user like utilizing the system?

Setting up of a usability testing framework includes precisely generating a scenario, or realistic circumstance, wherein the individual performs a rundown of tasks utilizing the product being tried while onlookers watch and take notes. A few other test instruments, e.g. scripted directions, paper models, and pre-test and post-test questions are likewise used to assemble a feedback on the software being tested. For instance, to test the attachment functionality of an email software, a situation would depict a circumstance where a man needs to send an email attachment, and request that him or her attempt this task. The point is to watch how individuals work in a reasonable way, with the goal that developers can see the problematic zones, and what individuals like. Techniques prevalently used to assemble data amid an usability test incorporate think aloud protocol, co-revelation learning and eye tracking.

For more on usability testing, enroll for a software course.

We hope that after reading this, you would have understood the concept and importance of Usability testing.

What Is Relation Between Software Testing and Quality ?

In this article, we are going to see whether there is any relationship between software testing and quality. We have heard both these terms n number of times. But have we thought about the connection between these two terms? Has any one told you about this?

In all probability, even a software testing class in Pune, would not enlighten you on this topic.

Well, by the time we reach till the end of this article, the association would become clear to us.

Let’s first try to understand as to what is software quality, before proceeding towards the testing part.

Software Quality :

Quality software is one which is to a large extent bug or defect free, on time delivered and inside the budget of the client or the customer and meets requirements and desires, and is maintenance friendly.

“the totality of features and characteristics of a product or service that bears its ability to satisfy stated or implied needs.” This is how ISO 8402-1986 standard defines quality to be.

Key factors that underline quality from a customer’s perspective, include :

  • Value for money

  • Durability

  • Best possible design

  • Proper functionality

  • Good post deployment service

  • Consistency

  • Reliability

This is how a customer perceives the quality of a product.

Who would accept a product which has no quality? Would you? The answer is a big “No”.

Now that we have come to know about quality and its importance, the question which would come to our mind is how to attain quality?

For that, we will now move our attention towards software testing.

What role does software testing play in the quality of a product?

Software Testing is vital on the grounds that we all commit errors/mistakes. Some of those mistakes are immaterial, however some of them are costly or perilous. We have to check everything and anything we create in light of the fact that things can simply turn out badly people commit errors constantly.

As seen in the quality part, there is no room for errors or defects. Quality does not have any room for them.

Since we accept that our work may have errors, that is the reason we as a whole need to check our own work. However a few oversights originate from awful assumptions and blind sides, so we may commit similar errors when we check our own particular work as we made when we did it. So we may not see the defects in what we have done.

The ideal way is, we ought to get another person to check our work in light of the fact that someone else will probably detect the flaws in our work.

This is where software testing comes into play. Software testing is focused towards finding bugs or defects in a product. The aim of which is to deliver a quality product. Now do you get the connection between the two?

There are quite a few reasons which obviously explains to us as to why Software Testing is vital and what are the real things that we ought to consider while testing of any application or a product.

Software testing is critical as a result of the following reasons :

  1. Software testing is truly required to bring up the defects and errors that were made amid the developmental phases.

  2. It’s fundamental since it ensures the Customer’s reliability and their satisfaction towards the application.

  3. It is imperative to guarantee the Quality of the product. Quality product provided to the customers ensures their trust and confidence in the vendor.

  4. Testing is fundamental with a specific end goal to give the assurance to the customers like the delivery of a quality product or an application having lower support cost and consequently comes about into more exact, consistent and dependable outcomes.

  5. Testing is required for a compelling performance of the software under consideration.

  6.  It’s imperative to guarantee that the application ought not come about into any failures since it can be exceptionally costly later on or in the later phases of the SDLC.

  7.  It’s required to sustain in the industry.

Hope that the relationship between quality and software testing would be clear to you by now.

For a career in software testing, where you would be assuring quality, go for a software testing institute in Pune that conducts a software testing course in Pune and learn the desired skills.

Software Testing Tutorial: Security Testing

Before going in for a software testing course in Pune, you can go through our testing related articles. This would help you to know the basics of software testing. That in turn will help you to better understand the topics taught in the software testing classes in Pune.

In today’s article we are going to see the concept called security testing. It is an important concept and every tester should be acquainted with it.

What do you mean by security testing?

Security Testing is a part of Software Testing which guarantees, that the various systems and applications in a company, are free from any loose ends that may bring about a major penetration. Security testing of any system is about discovering every single loophole proviso and shortcomings of the system which may result into lost data because of the employees or outsiders of the organization.

The major objective of security testing is to extract the threats in the system and measure its likely vulnerabilities. It additionally helps in recognizing all conceivable security breaches in the system and help the development team in settling these issues through coding.

Illustrative checkpoints for Security Testing:

Here are a few illustrative scenarios to give you a fair bit of idea about the security test cases.

  • Verify session and cookies time for application.

  • For finance related sites, Browser back button ought not work.

  • Password ought to be encrypted.

  • System or application ought not permit invalid users.

Security Testing types :

Security testing is divided into seven major types. They happen to be as follows:

– Vulnerability scanning

– Security scanning

– Penetration testing

– Risk Assessment

– Security Auditing

– Posture Assessment and

– Ethical hacking

  • Vulnerability Scanning: This is carried out through automation to filter a software against existing vulnerability signatures.

  • Security Scanning: It includes finding of system and network related vulnerabilities, and later give solutions for decreasing these risks. This checking can be performed for both Manual and Automated testing.

  • Penetration testing: This type of testing reenacts an attack from a malevolent hacker. This testing includes investigation of a specific system to check for potential vulnerabilities to an outer hacking endeavor.

  • Risk Assessment:This type of testing includes investigation of security risks seen in the organization. Risks are assigned as Low, Medium and High based on its priority. This testing prescribes controls and measures to lessen the risk.

  • Security Auditing: This is an internal review of Applications and Operating systems for security blemishes. Review or an audit should likewise be possible by means of line by line examination of the code.

  • Ethical hacking: It’s hacking an Organization Software systems. Not at all like malicious hackers,who penetrate a system for their own gains , the plan is to uncover security imperfections in the system.

  • Posture Assessment: This consolidates Security scanning, Ethical Hacking and Risk Assessments to demonstrate a general security stance of an organization.

Security testing methodologies :

In security testing, diverse methodologies are in practice, and they are as below:

Tiger Box: This hacking is typically done on a laptop which has an accumulation of OSs and hacking tools. This testing assists penetration testers and security testers to perform vulnerabilities assessment and attacks.

Black Box:  Tester is approved to do testing on everything related to the network topology and the innovation.

Grey Box:  Partial data is given to the tester about the system, and it is a blend of white and black box models.

To conclude :

Security testing is most imperative testing for an application and checks whether confidential information remains private. In this type of testing, tester assumes a part of the hacker and plays around the system to discover security related loopholes. Thus, security testing is vital in IT industry to ensure data protection in all possible ways.

A software testing institute in Pune , is the best place to learn more about Security Testing.

Software Testing: Difference Between Equivalence Partitioning and BVA

In this article about software testing, we are going to see the concepts of equivalence partitioning and boundary value analysis (BVA). These two are the very basic concepts in software testing, and are taught in various software testing class in Pune, conducted by various software testing institutions in Pune.

Let’s introduce this concept to you, so that it would be easier to understand while pursuing a course in software testing.

To begin with, boundary value analysis and equivalence partitioning are test case design techniques that come under black box testing.

Test cases related to input box accepting numbers in the range of 1 and 1000 with the help of BVA.

  1. BVA or Boundary Value Analysis:

It’s generally perceived that input values at the upper ands lower limit of input domain lead to more bugs in the system. More application blunders happen at the limits of input domain. ‘BVA’ Testing strategy is utilized to extract errors at limits, instead of finding those that exist at the centre of the input domain.

BVA is a next piece of Equivalence partitioning for creating test cases where test cases are chosen at the edges of the equivalence classes.

        Here is an illustration of the same:

  1. Test cases with test data precisely as the input limits of input domain i.e. values 1 and 1000 for our situation.

  1. Test data with values just beneath the extraordinary edges of input areas i.e. values 0 and 999.

  1. Test data with values simply over the limit edges of input space i.e. values 2 and 1001.

Boundary value analysis is frequently called as a piece of stress and negative testing.

Note: There is no firm rule to test just a single value from every equivalence class you made for the various input domains. You can choose different valid and invalid values from every equivalence class as indicated by your necessities and past judgments.

E.g. on the off chance that you separated 1 to 1000 input values in valid data equivalence class, then you can choose test case inputs like: 1, 11, 100, 950 and so forth. Same case for other test cases having invalid classes of data.

This ought to be an extremely essential and straightforward case to comprehend the Boundary value analysis and the concept of equivalence partitioning.

         2. Equivalence Partitioning:

In this technique the input domain data is isolated into various equivalence data classes. This technique is normally used to lessen the aggregate number of test cases to a limited set of testable test cases, as yet covering maximum requirements.

In short it is the way towards taking all conceivable test cases and setting them into classes. One test value is chosen from every class while testing.

E.g.: If you are testing for an input box accepting numbers from 1 to 1000 then there is no utilization in writing 1000 test cases for every one of the 1000 legitimate input numbers in addition to other test cases for invalid information.

Making use of the equivalence partitioning strategy, above test cases can be partitioned into three arrangements of input data called as classes. Every test case is a representive of individual class.

So in above case we can isolate our test cases into 3 equivalence classes of some legitimate and invalid inputs.

Test cases for input box taking numbers somewhere around 1 and 1000 utilizing Equivalence Partitioning:

1) One input data class with all valid inputs. Pick a solitary value from range 1 to 1000 as a valid test case. In the event that you select different values somewhere around 1 and 1000 then outcome will be same. Therefore, one test case for valid data ought to be adequate.

2) Input data class with all values beneath lower limit. I.e. any number below 1, as an invalid input data test case.

3) Input data with any value more than 1000 to depict third invalid input class.

So utilizing equivalence partitioning you have classified all conceivable test cases into three classes. Test cases with different qualities from any class ought to give you a similar outcome.

We have chosen one representative from each input class to create the test cases. Test case values are chosen in a manner that biggest number of attributes of equivalence class can be worked out.

Equivalence partitioning utilizes least test cases to cover majority requirements.

For a successful career in software testing, undergoing a software testing course in Pune, is the initial step.
