Regression Testing

[Level8]

Hello, I am student of Computer science. I am having knowledge about the programming. We are not having any knowledge about the Software testing, but as I have to submit the case study about the Regression Testing I need to know it. So, if you are having knowledge about it then please provide me that. It will be helpful for me to know more about it.

Regression testing is done to the software application for getting to know that whether the problem in the software when fixed existing working of the sotware is not harmed. It will provide you the working of the software is as per the earlier or not. It may possible that while modifying the software some of the unwanted changes have been done and you unaware about it. So, this Regression Testing provide you whether the software meets the goals or not.

Regression Testing is having following characteristics:

• It will make use of the existing test suites and test phase.
• Regression Testing is performed on software many times for checking the software working.
• It is a costly activity.
• It is the long running and complex process.
• This testing is performed in the Maintenance phase.

Regression Testing is having following four types of techniques:

1. Corrective Regression Testing
2. Progressive Regression Testing
3. The Retest-All Strategy
4. The Selective Strategy

Whenever you modify any content in your program then you must need to test that whether your contents have made changes to your existing program or not. That means it can affect your requirement and then you can't get your requirement. So, you need to perform the Regression testing. You can do so by rerunning existing tests against the modified code. While doing this you can make use of the strategies below:

• Test fixed bugs promptly
• Check the other changes
• Write a regression test for solving every problem
• Focus on functional issues
• Try it by making changes
• You need to also find out the overall change in the program

Regression testing is the testing method where you check that while fixing problems in the program your existing program is working properly or not. So that you can able know whether your system is working as per your requirement or not. This is normal part. If you are working in the big company then you will come to know that this is done by the Test Specialist. It will help you to know that the existing code is working properly or not.
