Regression Testing Examples: Manual and Automated
During software development, code changes are very common, but these frequent changes can unknowingly affect the other part/feature/functionality of the software. To ensure high-quality software, regression testing is needed. There are two ways (manual and automated) in which regression testing can be done. Let’s now understand these two ways of regression testing with the help of examples.
What is a regression test?
Regression testing is an important software testing method that involves re-running functional and non-functional tests to ensure that any new code change in the software does not affect the existing feature/functionality of the software.
Manual regression test
Manual regression testing is a process where testers manually draft the test cases and execute the test.
Example of manual regression testing: Consider a scenario, where the login feature is not working on a login page and a tester reports a bug stating that the login functionality is not working. Once the developers fix the bug, the tester tests it to make sure the login feature is working as expected. Simultaneously, the tester tests other functionality that is related to the login feature.
Automated regression test
Automated regression testing is a process where automated tools/frameworks are used to conduct tests automatically. This approach saves time and effort for testers as they do not have to do repetitive tasks manually.
Example of automated regression test: Suppose there is an application that has a functionality to ‘Add’, ‘Save’, and ‘Delete’. These functions allow app users to add, save and delete data. Now, developers are developing a new feature i.e., ‘Update’. This feature will allow users to edit and update the data. An automated regression test can be done here.
An automated regression test will help to ensure that with the introduction of a new feature (i.e. Update) existing features (such as ‘Add’, ‘Save’, and ‘Delete’ functions) or not affected. Regression testing is an important software testing technique as it helps in improving the quality and reliability of software.
There is a lot of effort required from the testers end to conduct a manual regression test as it involves a lot of repetitive work, therefore mostly automated regression test is preferred. Leverage regression test from a next-gen QA and software testing services provider to achieve quality software that delivers an unmatched experience to customers.
