Regression Testing

by adminDecember 10, 2017

Regression testing is a type of software testing which is used to verify that any modification or additions to the codebase have not introduced any bugs in the previous working version of the software. One of the reasons to perform regression testing is to find out whether a change or addition in one part of the application affects the other parts of the application. Sanity and Smoke testing are commonly considered as subtypes of regression testing.


When to perform Regression Testing?


Regression Testing is an essential aspect in assuring the quality of the software application, when a critical bug or a bunch of comparatively small bugs have been fixed freshly and when a new facet or new version of the software application is being released. For getting the highest benefit of regression testing, regression suite must be updated according to previous bug log and newly added or modified features. Not only maintaining the regression suite would help, you should also make a practice to execute it frequently so as to catch bug as early as possible. For the organizations practicing Agile, Continuous Integration or Continuous Development and other similar development methodologies, Regression testing is of utmost importance since each deployment comes with a risk of introducing new bugs.


Execution of Regression Suite


Hours of time spent for debugging the issue can be prevented by efficient regression testing strategies. Automating regression suite is now in trend. Many organizations start automating regression suite for the optimization of speed, efficiency, quality and the decrease of costs. The execution of regression suite should be frequent enough to remove any bottleneck timely. Through Rainforest QA, intelligent crowdtesting solution, regression testing process can swift along with the efficient maintenance of automated test suites.

Regression test suite can be run as unit tests to check discrete change in the codebase. It can also be run as functional test wherein gross usability of the end product can be verified. As mentioned before, to save time and manpower, regression suite can be automated. For CI and Agile projects, automating unit tests are much beneficial as they can provide immediate feedback for each deployment. Automating of unit test should also be executed at interface level so as to ensure overall quality of the application. Writing and managing automated test suites could be expensive and time-consuming. To verify the usability of the application, regression test suite must be executed by manually so as to best emulate the users’ behavior. However, manual execution can also be time-consuming and it can also create bottleneck to deployment.



Stepping of AI-based Rainforest QA in regression testing

Provision of wide coverage of browsers and concurrent execution of tests make it best suitable for carrying out swift regression tests. Rainforest can check for regression bugs quickly with its network of 50,000 qualified testers. The resource investment by Rainforest is minimal as compared to manual regression testing. The usability of the application can be verified easily by Rainforest as the automated regression test suites are run be human testers. Thus, Rainforest tests are more flexible than automated ones. It is a comprehensive regression testing tool facilitating developers to spend less time in ensuring the regression issues that are incorporated in the application during code updates. Hence, speeding up the regression testing during development and eliminate major bottleneck from developer-owned testing processes.
