What do you understand by Regression Testing?
Regression testing is an essential part of the testing lifecycle, whether you’re testing intricate, business-critical procedures or basic online applications. It protects your processes and apps from bugs as they develop over time.
Testing is necessary after every software upgrade to make sure nothing breaks. There are two distinct manual testing sides that you can identify:
Trying out new features
- Testing the functionality that is currently in place.
- The latter is the main focus of regression testing.
The possibility of fresh code affecting old code never goes away. Many of the most important functions are found in the existing components, and you run the risk of those operations not being tested. To help you improve your testing strategy, we’ve compiled a list of nine best practices for effective regression manual testing.
Best Practices and Tips to Conduct Regression Testing Effectively
1 Choosing appropriate test cases
The first stage in the regression testing process is choosing the test cases that address the most important and pertinent software system aspects. The system’s requirements, specifications, and user feedback, together with the risk and impact analysis of any upgrades or changes, should all be the basis for these test cases. Prioritizing the test cases based on their significance and frequency of execution is also recommended. Regression test cases are best organized, tracked, and stored using a test case repository or management tool.
2 Automating the execution of the test
Automating as much of the test execution process as possible is the second step in regression testing. In addition to improving uniformity and quality of test results, automation can save time, money, and effort. Additionally, automation can facilitate continuous software system supply and integration and quicker feedback loops. Automation is not a panacea; test scripts and frameworks must be carefully planned, designed, and maintained. Using a framework or test automation tool compatible with the software system’s technology, platform, and architecture is a good practice.
3 Taking care of the test data
Effectively managing the test data is the third phase in the regression testing process. The input and output data used to run the test cases and confirm the anticipated results is known as test data. Test data should be trustworthy, realistic, and pertinent to the tested goals and scenarios. It is imperative to isolate, regulate, and safeguard test data to prevent potential interference or contamination from other sources or tests. Utilizing a method or instrument for managing test data that permits the production, modification, and removal of test data is a good idea.
4 Summarizing and evaluating the test findings
Reporting and analyzing the test results is the fourth phase in the regression testing process. The outcomes and observations of the test execution, such as pass, fail, mistake, or defect, are called test results. Test results should be promptly and properly recorded, shared, and documented with all pertinent parties, including developers, testers, managers, and clients. Analyzing and assessing test results is also necessary to determine the underlying causes, effects, and fixes for any problems or flaws. A recommended practice is using a dashboard or test reporting tool that offers a thorough and graphical summary of the test results.
5. Enhancing the testing procedure
Continuous process improvement is the fifth step in the regression testing process. The set of procedures, guidelines, and practices used in the test process comprise the regression testing procedure. To guarantee the test process’s efficacy, efficiency, and quality, it should be routinely evaluated, optimized, and reviewed. The software development process, the software system’s business objectives, and the test procedure should all be in sync. Using a framework or test improvement model to direct the improvement of the test process is a good practice.
6. Taking note of the finest practices
Regression testing’s sixth stage is to study other testers’, companies’, or sectors’ best practices. The methods that have been tried, tested, and approved by others are known as best practices. Regression testing can be improved using best practices, which offer ideas, direction, and insights. Regression testing can present several frequent errors, traps, and difficulties that best practices can help to avoid. Using a test community or platform that makes sharing and learning about best practices easier is an intelligent idea.
7. Promote interdepartmental cooperation
Individual perspectives vary. Developers, functional testers, and business domain experts will view regression testing differently. Including multiple points of view is beneficial to prevent bias and blind spots—not to have too many cooks in the kitchen, mind you.
8. Establish and adhere to criteria
Setting up shared standards is crucial to streamlining test automation efforts. Determine universal test components and agree on naming conventions and documentation with your testing team. This method maximizes reusability by avoiding redundant components in your regression test suite. Keep a record of these guidelines, and revise them if your group finds better test methods. This dynamic document acts as a manual for testing procedures now and in the future. Implement an error-handling procedure that also logs and reports problems. This method makes it possible to identify and fix issues, quickly improving user experience. To increase the effectiveness of your debugging efforts, employ tools that come with visual debugging features to determine the precise time and reason behind test failures.
Wrapping Up
Manual testing done well is crucial to keeping software programs stable and reliable as they develop. Development teams can ensure that their applications stay reliable and efficient by following best practices, including thorough planning, ranking test cases, using automation, and incorporating testing into the CI/CD pipeline.
Regression testing efforts will be even more efficient and effective if they are continuously improved through training, feedback, and cutting-edge testing approaches. By implementing these methods, organizations may provide high-quality software that satisfies user expectations and advances corporate goals.
