How Do You Identify a Regression Test Case?

 

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.

 Regression testing is one of the functional testing method performed when there is a change made to the application functionality or code. This testing method is having a great role played in software testing as it helps in ensuring that the recent change made in the system or functionality has not affected the already existing features of functionalities of the system.

This testing practice in the software testing process is having an eminent role, but how to ensure if this performed at the right time on the right test case? Well, to be aware, find this space to find the tips that help in identifying the right regression test cases.

6 Tips for identifying Regression Test Cases

1. Test cases with Frequent Bugs: It is essential to include test cases that are usually error-prone and fail when there are small changes made to the code.
2. Test Cases with Recent Changes: Always plan for maintaining a record for the functionality changes being made. This way of maintaining a documentation record will help in including the test cases with changes made in the regression testing suite.
3. Test cases related to Core Functionalities of the application: Before planning for test case designing, teams have to find the test cases that determine the core functionalities. While identifying them make use of the traceability matrix for identifying all the test cases.
4. Test Cases with Complexities: For certain system functionalities, there can be a need for following a sequence of GUI events. Due to several sequential actions, there may be an occurrence of problems. Thus, the teams need to include such complex test cases in the regression test suite.
5. Include Integration Test Cases: Integration testing is not part of regression testing, but including integration test cases in the regression testing suite will help in fixing the bugs related to interfaces, messages, etc.
6. Include the test cases based on risks: Before planning to perform regression testing, teams have to prioritize the test cases at the beginning according to risks exposure.

Integration testing is a crucial testing method to validate the functionality of the individually tested modules after integration. With this testing practice, teams can ensure that the application being delivered works successfully without any bugs or errors. Leverage integration testing services from next-gen QA testing services provider for developing the best regression testing suite.
