A Guide to Applying Regression Testing in an Agile Environment
The continuity in business functions is ensured by performing regression testing in agile, without making any rapid changes in the software. There are various regression testing methods that can be used for performing testing in agile. The key factors that need to be considered are the priority of an application to be tested, availability of testing resources and test coverage.
In this article, you will get to know about the steps required to implement regression testing in agile environment.
Following are the six key steps that should be applied in order to implement regression testing in an agile environment:
1. Selection of test cases: The testing team must make the right decision in selecting only those test cases that are well-suited for performing regression testing in an agile scenario
2. An understanding of system integration testing: The testing team should be clear about the objective of system integration testing needs. All the software module dependencies should be validated by the team to know whether they are functionally correct and also make sure the maintenance of data integrity between separate modules for the entire solution. The communication between modules is focused by system integration testing.
3. An automated regression test suite should be established: Establishing an automated regression test suite should have a definite process in order to achieve a successful regression testing cycle. For example, end-to-end flow scenarios should be automated first, so that for all scenarios, basic regression testing can start soon.
4. Specify the changes: In certain scenarios, there might be changes made in the code needed in the test cases and for this purpose, the team needs to ascertain the specific changes that need to be made.
5. Assess the automation activity: The team needs to make sure the specific parts of the functionality can be automated. Analyze the automation process, so that the test cases can be ready for execution
6. The regression test results should be analyzed: Once the regression testing in agile is successfully completed, the regression test results need to be analyzed to ascertain the failure or success of a feature.
The significance of regression testing in an agile environment:
Regression testing plays a key role in the modern agile process. Agile represents a repetitive and incremental development methodology. With the software evolving through frequent changes and client demands, the inclusion of regression testing becomes a key factor in the software test life cycle process. In an agile scenario, the developed software undergoes continuous development and testing.
Along with new features being incorporated into the software, the software’s existing functionality should not be altered. The advanced software should be used by users without any issues. In order to maintain the credibility of the software, regression testing in agile is performed. A clear vision of the delivered software is provided by regression testing in agile to all the business stakeholders, post implementing the code changes.
Regression testing in agile makes sure that the changes made in the code do not introduce any bugs in the software. The risk in the software is mitigated through the regression testing method. It provides an assurance that the final product that is being delivered is as per the customer’s expectations. The new product can be developed by development teams, while stability can be maintained with every new product increment.
Developing complex software applications in an agile scenario requires both quality and efficiency in testing in order to make sure that any code changes do not impact the existing features. Regression testing makes sure that the application goes through continuous improvement throughout the software testing cycle.
Conclusion: If you are looking forward to implementing regression testing for your specific organization, then do get connected with a top-notch software testing services company that will provide you with a tactical testing roadmap that is in line with your project specific requirements.
