Why do you do regression testing?

What is Regression Testing?

Regression testing is a kind of testing that is done to confirm that changes in the code is not going to impact the existing effective functionality of the product. This is to confirm the product works fine with new functionality, bug fixes or any change in the existing aspect. Previously implemented test cases are re-executed in order to confirm the impact of change.

Regression test should be a part of the release cycle and must be considered in the test estimation.

When To Perform This Test?

Regression testing is normally executed after confirmation of changes or new functionality. But this is not the case ever. For the release that is taking months to completed, regression tests must be incorporate in the daily test cycle. For weekly releases, regression tests can be executed when the functional testing is over for the changes.

Regression testing is based on retest (which is simply to repeat a test). When retesting, the reason can be anything. Say, you were testing a specific aspect & it was the end of the day- you could not finish testing and had to stop the procedure without deciding if the test passed/failed. The next day when you come back, you execute the test once more – that means you are repeating a test you executed before. The simple act of repeating a test is a retest.

Regression test at its core is a retest of sorts. It is only for the special occasion that something in the application/code has changed. It might be code, design or anything at all that dictates the overall framework of the system.

A retest that is conducted in this situation to make sure that the said change has not made an impact on anything that was already working before is called Regression Test. The most common reasons why this might be conducted are because new versions of the code have been created (increase in scope/requirement) or bugs have been fixed.

Automated Regression Testing Tools

Automated Regression Test is the testing area where we can automate most of the testing efforts. We run all the previously executed test cases on a new build.

This means that we have a test case set available and running these test cases manually is time-consuming. We know the expected results, so automating these test cases is time-saving and is an efficient regression test method. The extent of automation depends upon the number of test cases that are going to remain applicable over time.

Suggested tool:

1. Ranorex Studio
2. Selenium
3. AdventNet QEngine
4. Regression Tester
5. vTest
6. Watir
7. actiWate
8. Rational Functional Tester
9. SilkTest
10. TimeShiftX

The Biggest Software Testing Challenges Faced By The Software Testing Company

Image
Surprising as it may seem, most of the problems that testing teams have to deal with every day are non-technical. Tests constitute an important part of software development but unfortunately are often undervalued by other stakeholders. The software  testing process aims at finding bugs before a potential client does, so good testers inevitably bring bad news most of the time. This is probably the reason why they aren’t very welcome guests in the developers’ sections: more defects equals more work for the development team. At this point, it’s important to remember that creating a software product involves many people with different roles, but with the same goal: the best quality assurance. The good first step towards overall success is understanding each other’s work and become aware of the problems that could be encountered on the way. In this article, we will present you how we grouped the common challenges of testers which can be solved more easily than you think.

Some Of The Key Advantages Of Software Testing

Image
Software testing is an essential part of assuring the quality of software. It is a plan which is carried out to discover the errors and mistakes when the whole process is completed. It is done to display the quality of a product which is already been tested. Its goal is to ensure whether the program is giving wanted output or not. It is a process which investigates the technical aspects of the program. It is used when the software is not able to function accurately. Software testing checks the security, perfection, quality, and totality of the program or software developed. There is much software available in market irrespective of their complexity and size. The software organization normally has targets to meet the specification of clients. For instance- the audience for banking software is totally different from video game software. Some of the key advantages: Saves a lot of Time: Manual testing on another hand can be time taking and at times might com
