A Brief Overview Of Software Regression Testing

Your team will need to decide the regression testing schedule that best meets your needs, but most organizations find it useful to perform regression testing on a strict schedule. This may be at the end of every work day, weekly, bi-weekly, or even after every single repository commit is pushed. Regression testing is successful as part of a comprehensive testing methodology within the Software Development Lifecycle. It must be cost and resource efficient while incorporating a well-designed strategy. Nowadays, regression testing is gaining momentum as an essential aspect of a dynamic, iterative development and deployment software process, and all testers should take advantage of it. The typical changes that may require a regression test include bug fixes, requirement changes, performance fixes, software enhancements, configuration changes, new features, component substitutions, etc.

regression testing meaning

Selenium offers a set of features used to automate web applications. It remains among the top tools for browser-based and cross-platform regression testing. Selenium supports automated test scripts that cycle through data sets and data-driven tests.

Ongoing Auditing And Testing

Read the details about overcoming automated regression testing challenges in Agile here. Manual regression testing was performed at the end of each iteration. Regression testing fully relied on test cases written during the development phase. The testing team ran the so-called sanity testing, an extensive test suite comprising about 200 test cases. The testing team regularly revised the test suite to delete obsolete or inefficient test cases.

There is a difference between re-testing and regression testing. Usually the regression testing is done by automation tools because in order to fix the defect the same test is carried out again and again and it will be very tedious and time consuming to do it manually. When any modification or changes are done to the application or even when any small change is done to the code then it can bring unexpected issues.

Regression Testing Example

If the regression testing at the end of every sprint was supposed to be done manually, it would eat up a lot of time and resources. Thus, automation of the regression test cases will play a very important part in saving the time and keeping the quality of a product consistent every sprint. Regression testing is performed to ensure updated code has not caused any existing functionality to break.

What is test life cycle?

STLC is a sequence of different activities performed by the testing team to ensure the quality of the software or the product. STLC is an integral part of Software Development Life Cycle (SDLC). As soon as the development phase is over, the testers are ready with test cases and start with execution.

Whenever a test elicits a previously undiscovered defect, a tester should write a test case that similarly induces the bug. Take a look at the full list of services offered by Performance Lab. If you regression testing meaning want to work with a team of experienced testers, be sure to contact us. We use a large number of tools to run test cases – the list includes TestLink, JIRA, HP ALM, Microsoft TFS, and many more.

Regression Testing: Strategy,

The regression testing and its test cases need to be updated whenever there is a new defect found. If the existing test cases are not covering the defects and changes that are done, so the new test case needs to be updated for covering those functionalities. In this type of testing, test cases have selected that need to be executed for testing. All the test cases won’t run for this method, only selected test cases used to run.

  • Typically, this is handled by the developer as defects are fixed.
  • Of course, data should be tested at the initiation of an application; however, testing should not stop there.
  • However, defects found at this stage are the most costly to fix.
  • This helps in maintaining the quality of the product along with the new changes in the application.
  • In the long run, automated testing can save an organization money spent on human resources, but only if they are fully prepared for the investment.
  • We have a team of ISTQB-certified testers experienced in creating coverage for regression testing, prioritizing and executing test cases, and giving a comprehensive report regarding the ways to improve the build.
  • It’s a real challenge for testers to decide when and where regression tests should be included, so it is important to design and maintain feasible regression tests.

Hence, to make sure our end users get the same experience with the product as they were getting even before the new changes were pushed, regression testing needs to be executed. The regression test cases are choosen from already created functional test cases. One of the preferred way of tracking the creation and execution of these test cases is via a requirement traceability matrix.

What Is Regression Testing? A Definition

In most cases, the software undergoes frequent changes and we spent a lot of time to execute these regression test cases and which leads to high-cost and time consuming. There are some challenges in performing regression testing, even REST API Testing though it plays a crucial role in the QA process. Retesting is a testing types to test the functionality or bug again to ensure that the defects which were found and posted in the earlier build were fixed or not in the latest build.

The overall purpose of regression testing is to easily and effectively uncover all possible software regressions, whether they were newly created (local / remote) or previously undiscovered . For more on how to speed up your regression testing, check out our post on how to speed up regression testing. Now that we have discussed the nuances of regression testing, let us look at some best practices that one create cool apps must follow. When a project grows, not only does the number of tests increase but the complexity too. In the shopping cart example above, the testing of the cart is logically done only after creating a new user and browsing to a search page. With an increasing number of tests, the sequential aspect may lead to a branching out of tests that might become difficult to handle without additional testers.

What Is Regression Testing? Definition, Tools & How To Get Started

After identification of the bugs in the source code, appropriate modifications are made. Then appropriate test cases are selected from the already existing test suite which covers all the modified and affected parts of the source code. In the end regression testing is performed using the selected test cases. An IT team can use a tool or platform to execute and optimize regression tests. A test management tool helps testers apply script automation, as well as trigger smoke and regression tests. In most cases, a regression testing tool leaves some level of manual test work for QA.

It is advisable for regression tests to be executed as often as possible throughout the software development life cycle. Perfecto can help you leverage automated regression testing — and test more, faster. Explore for 240 free minutes, test real user conditions, and get detailed analytics. The test cases in the regression test suite can be easily automated Hybrid App Development as these are stable and the process of automating them is called regression testing automation. During the SDLC, features are added to a product incrementally. When software development is done following agile methodology, new changes are pushed to the product every sprint and the expected output for a sprint is supposed to be a working deliverable.

If you want to get rid of regressions—and you should want to, believe me—then a suite of regression tests is the solution you seek. For starters, you waste money by having well-paid professional performing tasks that could be automated. The people regression testing meaning who are performing the tests could be doing more valuable tasks. Such tasks could have the potential to generate way more value. Finally, since the manual process is error-prone, then people are bound to make mistakes, which will result in losses.

regression testing meaning

After each new change to the codebase, just re-run all of the relevant tests on the suite to ensure they’re not failing. denotes an inclusive testing methodology that helps to reveal regression in software. More specifically, the procedure regression testing helps QA experts identify and rectify any glitches that may arise after bug fixes, performance improvements, or feature upgrades in software prior to its release.

Regression Test

Functional and regression testing should be performed to ensure that the changes do not impact the existing functionality of the software. If it is done manually then it will take a lot of time and effort, the testing can be done manually till there is less functionality or a small application. The application functionality goes on increasing as time goes on and it increases the regression scope. To save effort and time, the automation tool is mainly used to test the regression and application existing code.

But, more often than not, customers would still be using the existing functionalities much more than the new ones. As you and your team perform regression testing, there are some best practices to bear in mind. Turn to ScienceSoft for full-cycle software testing multi messenger facebook services and enjoy a high-quality application released on time. In the course of the project, one of the most frequently changed features was photo gallery management. And regression testing revealed that related functionality suffered with each new adjustment.
