Test Cases, Challenges And Objectives Of Regression Testing
A growing number of software development teams today favour agile software development over other development strategies. There’s no requirement to introduce Agile, but let’s return to it anyway! We know that the agile development methodology is adaptive in nature. It concentrates on creating a product based on empirical feedback associated with frequent testing by breaking down the product development means into shorter development cycles or sprints. Supports All Programming Languages Similar to influential operating systems and web browsers, Selenium also helps a large number of programming languages like Java, C#, Python, and Ruby. The feature makes the tool effective in testing all kinds of web application despite the programming language used by code writers.
Test Cases For Regression Testing It was observed from industry data that the good number of the bugs reported by clients were due to last minute glitch fixes to build side effects and therefore selecting the Test Case for regression testing is an art and not that easy.
Effective Regression Tests Can Be Performed By Selecting Following Test Cases – • • • • • •
Sample of Failure test cases. Sample of Successful test cases. Boundary value test cases. All Complex Test Cases. All Integration Test Cases. Test cases of Functionalities which has undergone more and recent changes. • Test cases which verify core features of the product. • Functionalities which are more visible to the users. • Test cases which have frequent defects.
An Incomplete Regression Test Plan: One of the significant things to know about Regression Testing services is that it works best when running early and frequently during each sprint. This is because running them later in the development cycle might yield unfavourable test results. Perform automated metrics against test scripts based on changes to the application.
• Version control test scripts and software attributes. • Maintain test scripts and document software attributes. • Document of the application development workflow. • Transform the workflow into test scripts. For the benefit of reduced deadlines, automated incremental regression testing exposed various more errors than were initially anticipated. Regression test automation also discovers new defects that may have arisen from new fixes.
Challenges of Regression Testing Communicating Business Value: Regression testing services make sure current product features are still in working properly. Communicating the importance of regression testing to non-technical managers within your business can be a difficult job. Complex: One more thing to analyse here is that as products get updated, they can grow quite complex making the lists of tests in your regression pack to grow to a huge amount.
Time Consuming: Regression testing is quite a time-consuming. Regression testing often includes running existing software tests again so testers might not be overly enthused at having to re-run tests.
Objectives Of Regression Testing: Pitfalls Of Results Of Regression Testing According to many organizations, the important functionality of the applications are checked once, and an assumption is drawn that it would continue to work well until changed intentionally. But, the fact remains that even minor modifications in code as a matter of routine are liable to have serious unanticipated side effects, which can probably break the functionality verified earlier. We should not become happy & get satisfied just because the system has responded as expected because there can be every possibility of the presence of introduced bugs, which may have escaped the detection.
Regression Testing Can Adopt The Following Approaches: Delayed Sprint Approach: In this approach, the regression cycle is normal and regression test cases that were applied for the second sprint include the functionality stories that were a part of the first sprint. Delayed Week Approach: In this approach, the sprint level regression test is not restricted to a timeline and can spill over into the next week. For example, if the sprint level regression test that is assumed to be performed in Week 2 is not completed, then it can scatter over to Week 3. The Traditional Testing Approach: In this approach, each and every sprint cycle is followed by sprint level regression test. Post a few successful sprint cycles, the application goes through one round of end-to-end regression testing.
