Software Testing Services: All the Truth About Regression Testing
Regression testing as a service helps to make sure that the system is bugless after performed modifications. Regression testing is aimed at the software’s major functions.
Testing process is carried out by a tester in order to identify defects. Debugging is done by a developer who determines why the bug (defect) appeared in code and applies necessary corrections to eliminate it. Debugging is required after software update to make sure that the problems have been eliminated. This procedure is named as confirmation testing or retesting.
After every software update, all the previous testing efforts become invalidated and the impact of the alteration is unknown.
Regression testing does not focus on entire functionality. Instead of this, it is done to check important / high-risk functionality while paying no attention to the more complicated functionality. For instance, when testing such app as MS Word the testers consider the functions like an opening, writing and saving documents. This functionality is critical because MS Word cannot perform without it. Functional testing services are provided to ensure that your software is free from bugs and can be released.
Implementation of the right testing strategy is of paramount importance. Testing strategy that does not include regression testing may considerably reduce the chances of finding hidden bugs. You are welcome to learn about the ways of dealing with the system update, namely with and without regression testing. Independent software testing companies perform complicated technical tasks to improve quality, performance and reliability of your software production.
No Regression Testing – Missed Bugs
There is a scenario with 3 test cycles and 3 test cases. In this case only certain fixes are to be tested, i.e. each test case is not performed during each test cycle.
In test cycle # 1 test cases A and C are successful but B is failed. After completion of test cycle 1, the developer is attempting to repair the defect that was detected by case B. In attempting to repair the bug in test case B, the specialist introduces a new functional defect covered by test case C. Then, test cycle 2 starts.
Regression testing – No Missed Bugs
This scenario also involves 3 test cycles and 3 test cases. Here, on the contrary, all the test cases are performed in each test cycle. In the test cycle # 1, test case B is failed, but test case A and C are successful. Test cycle # 2: we carry out regression testing, so test case A and B are retested. Due to regression testing we manage to find both bugs in test cycle #2.
Software testing services providers execute each test case in each test cycle to ensure that there are no new problems left unnoticed.
