One of the important phases in the software development cycle of software is the process of software testing.
This testing is conducted starting from the start of development of the software until the software is ready to be shipped to the market for sale. One type of software testing is functional testing and regression testing is one type of functional testing. One saying is that change is the only constant thing in the world. This is true for software. The existing software requires changes due to fixing defects, enhancements etc. Regression testing is done to ensure that enhancement, defect fixes or any other changes made to the software have not broken any existing functionality. Regression testing services is very important wherever there is iterative development of software. In iterative development, the developer adds another module with some functionality to the existing running module and one should make sure that addition of this module does not break the existing functionality. Regression testing is performed with the goal of discovering regression bugs. Whenever there are any changes in the software regression testing is performed. This ensures that the changes have not introduced any new bugs or affecting the previous functionality of the software without the new module. By doing this test one makes sure that functions that were performing satisfactorily continues to perform well with the addition of the new module. Many a times software change cause malfunctioning of the existing software. Regression testing helps in locating and eliminating the problem.

In certain cases, the addition of source code to a program will initiate new errors. This type of regression testing is a type of quality control to ensure that that new changed code is still in compliance with the original requirements and also that the unchanged code is not affected by any corrections made to the software. A very common way of regression testing is to just rerun tests that were previously run to check for new or reemerging problems. Regression testing is the method of verification. It verifies whether the bugs are fixed and the newly added features have not created any problem in previous working version of software. Regression means retesting the unchanged parts of the application. Test cases are re-executed in order to check whether previous functionality of application is working fine and new changes have not introduced any new bugs. When an additional program module is added to the existing running program it might cause new errors. The regression testing tracks it and the bug can be fixed. In any software development, you will come across errors and bugs reemerging after certain codes in the application are rewritten for fixing any bugs. There could be many reasons for this. Most of them are due to human errors. Some of the reasons for such errors are wrong coding, incorrect logic or not understanding the customer’s requirements. Some of the types of regression testing are as follows. local – this occurs when the changes made to the software bring in new bugs Unmasked – this happens when a change in the software brings previous bugs remote – occurs when a change to one part of software causes malfunctioning to another part of the same software Regression testing is not only useful in correcting a problem in the program, but also to track the output.
