Outsource QA: Regression Testing As One of the Main Types of Functional Testing
Regression testing is meant to check whether an updated program performs its functions in accordance with the requirements specification and interacts with other systems in a proper way. The program must behave correctly after it was changed or upgraded, i.e. new code is to be compliant with old code. This type of testing should be initiated each time when a programmer repairs a defect or adds new code for the new functionality. If you outsource qa, and regression testing, in particular, you will manage to improve quality of your software while reducing development costs by 50%.
Load testing is especially important if permanent corrections or enhancements are added in a software application to make sure that they have not affected the existing functionality. These changes can be as follows: defect fixes, code integration, migration of software to another operating system or database, new build, new functions, and other alterations.
If a number of concurrent users accessing the program has increased in comparison with the trial period then it should be subjected to regression testing.
The main objective of regression testing is to verify whether the software works as intended with new functionality. Since the testing requires execution of the same test cases repeatedly it is recommended to use automated regression tests and, as a result, to save time and effort. A set of previously executed test cases can be used on a new build.
Performance testing companies are available to repeatedly use existing test cases in order to verify your app’s functionality & performance under a heavy load. This kind of verification will help you identify and eliminate usability problems.
Once a single bug is fixed, it is time to retest the program to confirm that new bugs have not been introduced it in. Regression testing should be considered during release cycle and test estimation. When releases take long to be completed it is especially important to incorporate regression tests in everyday test cycle. Scope of regression testing depends on the scope of a new feature added to the app.
