Regression Testing

Regression Testing

Introduction:

Testing is an essential component of the software life cycle, to develop efficient software which doesn’t misbehave at any point of time, you must have gone through different types of testing. To ensure the performance and behavior of software there are some important testing namely Smoke Testing, Sanity Testing, and Regression Testing, and so on. Though there are many types of testing these are some important testing done by Testers for ensuring the smoothness of developed Software.

Regression Testing

As the name suggests regression which means to come back again and again, so Regression Testing is testing which is done to ensure that the recent changes done in the software don’t affect the whole functionality of the software. The change may happen because of many reasons like fixing the bug, adding some new functionality in the software, deleting some unwanted feature of the software, updating the software for the new platform, In doing all these our source code may get disturbed or rewritten and thus impacting the whole software, so for ensuring that these changes do not affect our current software, we perform regression testing.

Live Scenario: 

Suppose that a client wants software that allows chatting through Bluetooth on all android platforms, and the company accepts that demand and the design, as well as the test cases, are prepared.

Soon the developer started working on it after making the software the Q/A team start testing it with the help of test cases prepared and found that the end-user is not able to connect with another user through Bluetooth and reported the bug to the developer, then the developer starts to make certain changes in the source code to fix the code, now the tester will again test (Regression Testing) it from the starting to ensure the overall functionality is fine after fixing the bug. When the complete software is tested then it is ready to go live and available for the end-user.

After a certain point of time after getting some feedback the client wants that software can also be connected through WIFI and available for iOS also, the developer now rewrites the code to ensure the client requirement is fulfilled and deliver it to Q/A for testing. The Tester will perform “Regression Testing” with newly developed Test cases and also the old one for ensuring bug-free and efficient software that meets the client’s requirement and after testing regressively it will go live.

So, the above example makes it clear for you what regression testing is and why it is performed.

Regression Testing Tools:

1) Ranorex Studio: It is the best tool for automation of desktop, web, and mobile apps having Selenium WebDriver.

2) Selenium: Used for automating web applications having an open-source tool. Used in browser-based regression testing.

3) Quick Test Professional (QTP): To automate functional and regression test cases we use HP Quick Test Professional. HP Quick Test Professional uses VBScript language for automation. It is a Keyword-based tool having Data-driven.

Conclusion:

Every software in the present scenario needs to be updated time to time as to survive the competition in the market, and thus updating a software requires a small or major change in the source code which may affect the overall functionality, so to ensure that the overall software works fine even after updating it we perform regression testing.
