Characteristics of Reliability testing

Today, we will have a look at Reliabilty testing. We will try to understand the concept covering the various aspects related to it. Testing classes in Pune train students in the software testing domain. To get more details about the same, you can search for software testing courses in Pune.

Let us go ahead with reliability testing.

Reliability Testing is all about execution of an application with the goal that bugs are found and resolved before the system is deployed. The aim of reliability testing is to decide the product reliability, and to check if the software meets the customer’s reliability demands.

Characteristics of Reliability testing:

  • Reliability alludes to the consistency of a measure. A test is viewed as reliable in the event that we get a similar outcome more than once. Software Reliability is the likelihood of failure free software functioning for a predefined time-frame in a predetermined environment. Software Reliability is additionally a critical element influencing system reliability.

  • Reliability testing can be carried out at different levels. Complicated systems can be tested at component, unit, subsystem, system, circuit board and assembly levels.

  • As indicated by ANSI, Software Reliability is defined as: the likelihood of failure free software operation for a predefined time-frame in a predetermined environment. Software Reliability is not an immediate function of time. Electronic and mechanical parts may turn out to be towards becoming “old” and destroy with time and use, however software won’t rust or destroy amid its life cycle. Software won’t change after some time unless purposefully changed or updated.

  • Reliability testing will have a tendency to reveal prior those failures that are in all likelihood in real-time operations, in this manner coordinating endeavors at settling the most imperative shortcomings.

Software testing course in Pune with placement is the place where you can get job assistance in addition to training.

Software reliability plays an important role in software quality. Software reliability can be divided into three parts as below:

  1. Modeling

  2. Measurement

  3. Improvement

  1. Modeling:

Software reliability modeling has developed to the point that significant outcomes can be gotten by applying appropriate models to the issue. There are a number of models that exist, yet no single model can catch an essential measure of the software characteristics. Assumptions and abstractions must be made to simplify the issue. There is no single model that is all inclusive to every one of the circumstances.

  1. Measurement:

Software reliability estimation is naive as of now. Measurement is a long way from commonplace in software, similar to other engineering related fields. “How great is the software product, quantitatively?” As straightforward as the question may be, there is still no clever response. Software reliability cannot be measured directly, so other related aspects are measured to gauge software reliability and compare it with other products. Development process, shortcomings and failures found are all elements identified with software reliability.

  1. Improvement:

Software reliability improvement is difficult. The trouble of the issue originates from deficient comprehension of software reliability and on the whole, the attributes of software. Up to this point there is no great approach to vanquish the complexity problem of the software. Complete testing of a modestly complex software module is infeasible. Free of defects software product can not be guaranteed. Real-time constraints of time and spending plan severely restrains the efforts put into software reliability improvements.

For an organization to perform reliability testing is generally costlier than the typical functional testing as it requires more change and swings to distinguish the application breakpoint and loads of technical abilities and experience on the testing resource side.

If you are interested in doing a software testing course, look for software training institutes in Pune and then choose the best one.

The Role of Volume Testing In Software Testing

As a part of our software testing article series, today we will be seeing what is volume testing, and the various aspects related to it.

With proper professional training, you can tap the various opportunities for software testing jobs in Pune. As far as training in software testing is concerned, a software testing course in Pune can be of great help. It would train you in various software testing related modules.

Now, let’s focus our attention on understanding Volume testing.

It comes under the category of non-functional testing. Volume testing is nothing but testing a software application or product with a specific amount of data. E.g. in the event that we need to volume test our application with a particular database size, we have to extend our database to that size and afterwards test the application’s performance based on it.

  • Volume testing” is a term stated and elaborated in The Art of Software Testing, 1979, by Glenford Myer. As per his definition, Volume testing is “Subjecting the program to heavy volumes of data. The purpose of volume testing is to show that the program cannot handle the volume of data specified in its objectives” – p. 113.

  • The role of volume testing is to decide system performance with expanding volumes of data in the database.

  • Test cases are extracted from design documents

  • Data to be tested is normally generated with the help of a test data generator.

  • A small amount of data is tested during the developmental phase.

  • The test data used is just to assess the system performance. Test data is not required to be logically correct.

  • Post the completion of testing, results are logged and tracked to bring it to closure.

  • Software performance deteriorates with time since there is huge amount of data overtime.

Checklist for Volume testing:

  • Checking the response time of the system.

  • Check for any data loss.

  • Check if data is being overwritten sans any notification.

  • Check whether data is being stored in an incorrect manner.

Testing courses in Pune usually help in terms of providing job assistance as well.

Examples of Volume Testing:

In the event that you are planning for a software to be utilized on 1,000 PCs, you ought to reproduce the utilization of the system on a similar number of PCs. That is what you call as volume testing. All the actual exercises that will be performed by the users ought to be reproduced and performed. This will incorporate opening of files, creating documents, and processing data or any utilization the end user will probably utilize the system for.

In the event that you need to test the application with a database of a particular size, the database of the system ought to be extended by adding more data to the system database until it meets the desired objective.

Volume testing vs load testing:

Volume testing makes sure if the software under question functions as per expectations for certain volume of data. Volume can be built by increasing size of the document. As far as load testing is concerned, load tests checks the system performance when the load is increased. Load testing here will be increasing the number of files. Volume testing can be utilized to quantify the throughput while load testing can be utilized for measuring the performance.

Volume-testing services incorporate test management, development of test labs, test strategy designing and planning and test plan development, development of automation testing systems, assistance in making test script, developing test scenarios, test case execution and provide quantifiable test reports.

Hope that you found this article on Volume testing, to be informative. We will come up with more topics related to software testing.

Meanwhile, for learning software testing, you can search for software testing classes in Pune.

Aspects Related To Endurance Testing

Today we are going to study the concept of Endurance testing in software testing. Let’s try to understand what it is and its purpose. Testing courses in Pune cover this topic along with other software testing related concepts. For undergoing a testing course, select a software testing institute in Pune and take admission.

Endurance testing falls under the category of non functional type of software testing. It is also termed as Soak testing.

Some aspects related to Endurance testing:

  • It basically comes under non-functional testing.

  • It is intended to check the memory leaks.

  • The objective is to find out how the system acts under continuous use. That is, to guarantee that the throughput or/and reaction times after some long stretch of continuous activity are as good or superior than at the start of the test.

  • Endurance testing consists of testing a system with a critical load reached out over a noteworthy time-frame, to find how the system functions under sustained load. For instance, in software testing, a system might continue to function on exactly as expected when tested for 1 hour, yet, when the same system is tested for 3 hours, issues, e.g. memory leaks lead the system to break down or act in a random manner.

Time frame necessary for Endurance Testing:

Endurance testing requires a lot of time since the basic intention is to verify performance of the system over delayed use. The time span for a test is finalized on the premise of variables like client involvement, actual production, utilization of system and so on. One test for such type of testing may take well more than 12 hours to be finished. A few organizations even carry out this type of testing for a period of one year.

If you are looking for a job in the field of software testing, then you have the option of joining a software testing course in Pune with placement.

Endurance Testing Lifecycle:

  • Analysis of requirements:

In this stage, the prerequisites are analyzed and understood. This phase is in charge of recognizing which type of testing tramadol should be performed. E.g. if it’s a brand new software then, this testing will probably be pin scope. In any case, in the event that it is only an addendum to an established software, then, endurance testing can be ruled out.

  • Test plan:

Amid this phase, resources, time frames and cost estimation is carried out for the test cases. The extent of automation and manual testing too is chosen amid this stage. Endurance testing is done utilizing automation tools like LoadStorm. As examined before, this testing is a tedious procedure. The schedule is chosen in light of the variables like budget, client requirement and so on.

  • Test case development:

Test Cases are designed amid this phase. The workload and duration for testing is chosen amid this stage. An endurance test case may keep running from 12 to 72 hours in view of the requirements. In any case, once in a while, client can give clear specifications and duration can be decreased up to 3 or 4 hours, according to client need.

  • Testing environment:

Test Environment is created amid this stage. The environment for such type of testing ought to be disengaged from other test conditions. It ought to be like genuine production environment with the goal that outcomes produced are exact and consistent. Likewise, original environment ought to never be utilized for testing as a system crash amid testing may affect the environment and cause loss of data.

  • Test case execution:

Problems like memory leaks, moderate reaction time, database connection issues are distinguished and resolved.

  • Closure:

In view of exit criteria set amid test planning test cycle ought to be shut. Exit criteria could be defined based on the timeline or the defects found.

Thus, we saw the various aspects related to Endurance testing. Testing classes in Pune teach software testing in a professional manner. You can join them for a successful career in this field.

Overview On Documentation Testing

This article is dedicated towards documentation testing. We will elaborate the concept and see what it is all about. Software testing training in Pune, can turn out to be useful for those who want to become a software testing professional. It would also help them to land a software testing job in Pune.

Getting back to documentation testing, it comes under the category of non-functional type of software testing.

  • It is a type of non-functional testing.

  • Documentation testing can begin at the absolute starting point of the software process and subsequently spares a lot of money, since the prior a defect is discovered, the less it will cost to be resolved.

  • Any pictorial or written information portraying, characterizing, determining, revealing, or ensuring activities, requirements, methods, or results’. Documentation happens to be as essential to a product’s prosperity as the product itself. On the off chance that the documentation is poor, non-existent, or improper, it affects the quality of the product and the seller.

  • This is a standout amongst the most practical and effective ways to deal with testing. In the event that the documentation is wrong: there will be major and expensive issues. The documentation can be tested in various distinctive approaches to a wide range of degrees of complexity. These range from running the docs through a spelling and grammar checking tool, to physically inspecting the documentation to evacuate any equivocalness or irregularity.

  • According to the IEEE Documentation portraying plans for, or consequences of, the testing of a system or module, Types incorporate test case specification, test incident report, test log, test procedure, test plan, test report. Subsequently the testing of all the previously mentioned documents is termed as documentation testing.

Testing classes in Pune usually teach documentation testing as well.

Why documentation testing is not given importance?

Why documentation testing is not given as much importance as different other types of testing might be we are ignorant some place in defining the Documentation testing. Documentation testing is in fact the most vital amongst all the testing types as it verifies the grammar, uncertainty, and irregularity in the capacities to be actualized and performed. Product documentation is as much critical as the product itself. Hence if documentation will be poor, non-existent, or totally wrong it won’t just influence the nature of the product but additionally the company. Unlike the past where you simply need to run a grammar check to guarantee the quality of a document; presently, software documentation comprises of a noteworthy piece of the product improvement that is 70% to gauge. Guaranteeing that documentation is right is a piece of a software tester.

How can it be performed?

Documentation Testing can be performed utilizing two techniques one of them is testing the document by verifying spellings and gramar utilizing the accessible instruments and the second one expresses the need of manual investigating of documents to find blunders, equivocalness, and irregularities.

Four key zones for documentation testing incorporates Examples, instructions, messages and samples. Instructions will be expected to be well ordered execute the test scenarios for looking blunders or their exclusion. Further examples can be given to expand the GUI modules, commands, syntax and interfaces to demonstrate executed yields or pin focuses. Inconsistencies additionally should have been dealt with errors as they can confound the users and these ambiguities will bring about much damage if the user of the system will be a new user. So irregularities are vital to fix. Examples will be required if there should arise an occurrence of any issue that jumps out at the user. Amateur Users will check the documentation for any disarray as they shouldn’t be such a great amount of proficient about the system any dependably go to the documentation for any perplexity and we ought to have the capacity to address the issue.

These were a few things about documentation testing.

You can check out the prospects of software testing in Pune, and then decide about making a career in it.

Security Testing: A Critical Part of Software Testing

Security testing is an important part of software testing and is included in the curriculum of most of the software testing courses in Pune. Look out for a software testing course in Pune with placement. This would help you in getting a job in this field.


Let’s get into the various aspects related to security testing.

Security testing fundamentally refers to a type of software testing that is done to check whether the application or the software is secured or not. It verifies whether the application is powerless against attacks, in the event that anybody hacks the framework or login to the application with no prior approval or authority.

It basically is a type of non-functional testing.

Security testing characteristics:

  • The six basic parameters that need to be covered under security testing are as follows:

– Integrity- The application and related data is authentic.

– Authentication- Data is genuine or not and the application origin.

– Availability- As the name suggests, this tests the accessibility of the software application i.e. it is dependably up and running, data and administrations are accessible at whatever point required. Likewise, this incorporates the bckup records which are promptly accessible of any disappointment happens.

– Confidentiality- Data or information is protected from theft.

– Authorization- Certain users should have access to authorized functions only.

– Non-repudiation- Assurance that the receiver and sender of information can’t deny the fact of having sent or received the data.

  • It is a process to discover that a information framework protects information and keeps up functionality as proposed.

  • Software security is about making software carry on in the sight of a malicious attack.

  • The security testing is carried out to check whether there is any data spillage in the sense by encrypting the application or utilizing extensive variety of softwares and hardwares and firewall and so forth.

For a software testing job in Pune, search on the various job portals.

Security testing is a huge subject. Each technology that you utilize, regardless of whether it’s a programming language like .NET or PHP or an element like input validation or authentication, presents another arrangement of security vulnerabilities. Today, we are occupied with giving you a fundamental idea of what security testing is and how it is performed.

Security testing must begin at an early stage to limit defects and cost of quality. It is a decent practice to begin security testing at the time of prerequisite assembling, this guarantees quality of the finished product will be high.

There is no standard approach to test the security of an application, it absolutely relies upon the reason it serves and what are the security hazards present in it. Each time begin security testing by testing the UIs, this is the primary spot of entry for hackers and unlawful users. At that point think what a hacker would likely do in the event that he gets the access or entry into the system, regardless of whether he will steal the credit card data or get access to some personal files and so forth begin some destructive testing i.e. to test what application or system can’t do and after that focus on the error messages you get. When you are finished with every one of these sorts of testing, attempt and burrow further and see what could be the escape clauses with regards to security at the coding level. With some experience, you will have the capacity to perform security testing in a better manner.

Security testing happens to be an important part of software testing and cannot be ignored at any cost. Testing classes in Pune can give you a detailed insight into security testing.

Getting To Know Baseline Testing In Software

In this article, we are going to discuss about the concept of baseline testing in the software arena. It is a lesser known concept and might not be a part of the software testing courses in Pune. Best software testing institute in Pune, is the place you can go for getting trained and placed in this domain.

Baseline Testing happens to be one of the sorts of non-functional testing. It alludes to the approval of documents and specifications on which test cases would be outlined. The requirement specification validation is termed as baseline testing.

  • Baseline testing additionally helps an incredible deal in taking care of the vast majority of the issues that are found. A lion’s share of the issues are explained through baseline testing.

  • For the most part a baseline is characterized as a line that structures the base for any development or for estimation, comparisons or calculations.

From the technical perspective,

Baseline is an official document which goes about as a base record for future work. Talking in layman dialect, for constructing a building, you require a foundation. Same thing applies to testing. We have to create a Baseline, from which additionally testing can be carried out. On an initial level, it is vital to realize that it is non-functional testing which implies it has nothing to do with testing of functions of application. Or maybe testing of document is done which establishes strong base of the work to be done in future. So one might say that it goes about as a base for development in times to come, whatever it is. It might be execution, test case development etc.

There are many software courses in Pune that provide both training and placement in the testing field.

Once the Baseline Testing is performed and the SRS document is freezed, we are prepared to advance and begin the development and testing process. For testing, we can begin planning test case in light of requirement document. Principle advantage of Baseline Testing is that we can expel errors in necessity in early phase of Software Development Life Cycle and evacuate such a large number of issues and efforts at later stage and help us conveying the venture with least rework and less exertion.

Assume that Baseline Testing is not done appropriately and Business Requirement Document is not legitimately settled, then SRS created on the premise of Business Requirement Document won’t be legitimate and Design Document will likewise not be right and hence every one of the exercises of development and testing won’t be according to client’s wish as there might be slight mix-up while taking the prerequisite or the necessity was not baselined legitimately. From this we can see how much essential is Baseline testing.


Along these lines we see that Baseline testing is of how much significance and unless and until requirements document is not legitimately approved or as such if Baseline testing is not carried out, there will be lots of issues in later stage and efforts put in will be a great deal more in tackling the issues which will be only wastage of energy and time and new prerequisites will be taken and need to undergo all stages of Software Development Life Cycle, keeping in mind the end goal to resolve the issues totally. Along these lines, we can state that Baseline Testing understands many issues at prior stage, cost reduction, energy and time to the organization at the later phase of Software Development Life Cycle.

Thus we can now see the importance of Baseline testing in the software industry.

Understanding the Difference Between Severity and Priority

As a part of our software testing series, we focus on one concept each time. Today, we will try to understand the difference between severity and priority. It often becomes confusing as far as these two terms are concerned. We will try to simplify them for you. For studying this subject in depth, one can take the help of software courses in Pune. Many software institutes in Pune conduct such courses.


Regarding the question, what is the difference between severity and priority?

  1. Priority:

Priority characterizes the request in which we ought to determine a defect. Would it be a good idea for to fix it right now, or can we wait for sometime? This priority status is told by the tester to the developer specifying the time period to resolve the defect. On the off chance that a high priority is set, then the developer needs to fix it as early as possible. The priority status is set in light of the customer prerequisites. For instance: If the organization name is incorrectly spelled on the landing page of the site, then the priority is high while severity is low to fix it.

Types of priorities:

  • High:

The defect must be settled at the earliest opportunity in light of the fact that the defect is risking the application or the product on an extreme level. The system can’t be utilized until the repair work has been carried out.

  • Medium:

The defect ought to be resolved in the typical course of development exercises. It can hold up until a new build or version is developed.

  • Low:

The defect is an aggravation which ought to be repaired, however repair can be conceded until after more genuine defect has been fixed.

Learn the other concepts related to software testing by joining software testing classes in Pune. Let’s get on with severity now.

2. Severity:

It is the degree to which the defect can influence the software. At the end of the day it characterizes the effect that a given defect has on the deliverables. For instance: If an application or site page crashes when a remote link is clicked on, for this situation clicking the remote link by an user is rare yet the effect of application crashing is extreme. So the severity is high yet priority is low.

Types of severity:

  • Critical:

The defect that leads to the termination of the total system or at least one segment of the system and causes broad corruption of the data. The fizzled function is unusable and there is no worthy option strategy to accomplish the required outcomes then the severity will be said to be critical.

  • Major:

The defect that leads to the shut down of the total system or at least one part of the system and causes extreme corruption of the data. The fizzled function is unusable yet there exists an adequate option strategy to accomplish the required outcomes then the severity will be assigned as major.

  • Moderate:

The defect that does not bring about the closure, but rather makes the system create erroneous, fragmented or conflicting outcomes then the severity will be expressed as moderate.

  • Minor:

The defect that does not bring about the closure and does not harm the ease of use of the system and the coveted results can be effectively gotten by working around the defects then the severity is said to be as a minor one.

  • Cosmetic:

The defect that is identified with the upgrade of the system where the progressions are identified with the look and field of the application then the severity is expressed as a cosmetic one.

Thus we saw the points of differences between severity and priority. For more details on this, a software testing institute in Pune would be of great help.

Software Quality Management and It’s Associated Phases

In this article, we will study about Software Quality Management and its associated processes. In order to study this and other topics related to software testing in greater detail, opt for a software testing course.

According to ISO 8204 definition of quality,

Totality of characteristics of an entity that bears on its ability to satisfy stated and implied needs.

This means that any software product under consideration, complies with the stated requirements.

Different phases involved in Software Quality Management (SQM):

Software Quality Management (SQM) portrays the processes that guarantee that the Software Project would achieve its objectives i.e. meet the customer’s desires.

Any particular phase of SDLC has its own particular stages of planning, execution, maintenance, control and report generation. In like manner, Software Quality Management has the accompanying three classes or key stages:

  • Quality Planning

  • Quality Assurance and

  • Quality Control

Let’s take a look at them one by one.

  • Quality Planning:

Quality Planning is a standout amongst the most vital parts of Software Quality Management. It is the initiating phase of SQM. Through legitimate planning, we can guarantee that the processes that make a product are inspected effectively to meet the general venture objective. The supervision of Quality Planning procedure is taken after diversely by various organizations. It has been depicted in various Quality Policy and Documentation crosswise over different organizations.

Other industry benchmarks identified with the Software Project can be alluded to Planning stages when required. These go about as Standard contributions for some particular ventures.

Different tools and methods are utilized to design the quality plan. Few of such tools and systems are described in short in this article. Here are some outlines:-

Benchmark: Deciding on the current product standards by contrasting with the exhibitions of comparable tools which is as of now exist in the market.

Cost of Quality: The aggregate cost of value is a summation of counteractive action, examination and costs of failure.

Design of Experiments: Statistical information can be utilized to decide the components affecting the Quality of the product.

Other tools: There are different tools utilized as a part of the Planning procedure, for example, Cost Benefit Analysis, Cause and Effect Diagrams, System Flow Characteristics.

The greater part of the above key focuses helps in the arrangement of a Quality Management Plan for a specific venture.

  • Quality Assurance:

Quality Plan which is made amid planning is the input to Quality Assurance Process. The Assurance stage is having the accompanying data sources:

1. Quality Audits

2. Different Techniques used to assess performance of the venture

Quality Assurance Process helps us to guarantee that the Project is taking after the Quality Management Plan. The tools and the procedures which are utilized as a part of Planning Process, for example, System Flow Characteristics, Design of Experiments, Cause and Effect Diagrams can be executed here as well, according to necessities.

  • Quality Control:

The following stride to Quality Assurance Process is Quality Control. This particular stage consists of the following inputs:

1. Quality Management Plan.

2. Quality Standards for the Project.

3. Real Observations and Measurements of the work done or work in Progress.

The Quality Control Processes utilizes different tools to Observe and Measure if the work is carried out or not. On the off chance that the Work is done and it is found that the output is not palatable then it can be sent back to the development team for fixing.

In the event that the work done meets the prerequisites as characterized then it is acknowledged and released to the customers or clients.


Documentation is known to be the implicit part of SQM. In Software Quality Management Processes, documentation part is of most extreme significance. Client Requirements of any Software Project should be adequately documented. Else, software ventures fail to screen different phases of the life cycle. A situation where the Requirements of any Software Project are not adequately documented, it is very conceivable that there can be a circumstance where client’s requirements are not known to the testing team. Thus, testing team won’t have the capacity to test the developed software venture as per the client’s necessities or desires.

The lacking data may bring about deficient “Software Quality”, which is not at all acceptable.

For a certificate course in software testing, join a software course at a software institute in Pune.

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’.

For more on these testing tools and to learn them, join a software testing course in Pune.
