Regression Testing Guide

Regression testing is one of the more important parts of software testing. It must be part of your software development cycle if you regularly make changes in the software to add some new features; to improve the functionality of existing features; making changes in the database; fixing existing bugs; etc. Regression testing is a systematic process of testing the software for its quality to assure that the changes in the code have not adversely affected other features of the software. The best regression testing services test the already tested modules after any change is made in the code to assure high quality and no existence of bugs.

Regression testing is different than retesting and that’s the reason it needs expertise and experience which a software testing expert holds. If you are an aspiring software testing engineer or a curious entrepreneur, this article shares a step-wise guide to perform effective regression testing:

Step 1: Define test cases and components

Regression testing is different than retesting. You can’t afford to retest everything from scratch, so you need to define the test cases that you want to run again. You can also write new test cases, as and when needed. You should also define the components that need to be tested again. The choice of content varies from software to software. General candidates for regression testing are the components that are fixed for bugs or previously had bugs because the bugs could have reoccurred or not fixed as per the expectations.

Step 2: Setting up priority

The organization needs to make a collaborative decision to define the final test cases to run for regression testing. This process involves stakeholders, developers and testing experts. This can be a one-time process when you are going to run the regression test for the first time. This assures everyone is informed about the process and investment.

Step 3: Define entry criteria for regression testing

Regression testing can be expensive if not used wisely. One of the wise decision necessary is defining the entry criteria for it. Here, the entry criterion means minimum eligibility and set of conditions that have to be true before the QA expert starts the testing.

Step 4: Define the exit criteria for regression testing

Similar to the entry criteria to start the regression testing, the exit criteria should be defined in advance. Here, the exit criterion means the eligibility or minimum conditions to be met before closing the test phase.

Step 5: Create and stick with the testing schedule

Whether you are going to use automation testing or manual testing to perform the regression testing, you need to define a schedule for the same. The schedule will define when and how the test cases will be executed and till when. Furthermore, this testing schedule has to be followed strictly to get effective results.

Concluding Note:

The regression testing is one of the software testing processes that are vital to assure the best performance and quality of the software all the time. It has to be performed in a step-wise manner with the best practices explained in this article.
