Regression testing services we provide

Functional regression testing

This regression testing service is the most common form of regression testing, which checks whether newly introduced modifications won't interfere with the application's existing functionality.

Automation regression testing

Want test cases stable, worth maintaining, and repeat-friendly? Try automated regression testing services. We achieve more with our approach by leveraging trending automated regression testing tools.

Unit regression testing

Want test cases to be stable, maintainable, and repeat-friendly? Try automated regression testing services. We achieve more with our approach by leveraging trending automated regression testing tools.

Progressive regression testing

All regression testing services provide qualified professional testers. We always check software applications to ensure that none of the features have been revised in an updated or new version.

Corrective regression testing

This regression testing service can easily reuse an existing test case to perform the required test. Our expert testers perform high-quality remedial testing to ensure software improvements.

Selective regression testing

Choose this regression testing service to check how the added new code affects the existing code. Our internal testers perform this testing to ensure that code updates won't lead to system failures.

What are regression testing services?

Regression testing in software development is quality testing used to verify that new changes to the code base have not affected the application's existing functionality.

Depending on the client's needs, we provide different regression testing services, including:

  • Functional regression testing
  • Automation of regression testing
  • Single regression testing
  • Progressive regression testing
  • Corrective regression testing
  • Selective regression testing
Why are regression testing services critical?

With every new change, bug fix, system update, or a new feature, the likelihood of software problems increases. If you don't do regression testing, bugs can go unnoticed. Regression testing helps maintain the quality of each release. It's part of agile testing, necessary for experienced agile teams to deliver quality software consistently.

Because regression testing service requires multiple retesting of existing features, it's an excellent case for automation. Regression testing services will help you get:

  • Regression test automation strategy
  • Methodology of continuous testing
  • 70-90% coverage of manual tests
  • Parallel execution of the test
  • Risk-based regression
  • Test case maintenance
What are the challenges with regression testing services?

Regression testing services are essential because they can help detect defects very early when the cost of fixing them is still meager. However, there are five critical problems with it:

  • It's perceived as low-value because QA engineers have to produce it repeatedly
  • The cost of testing is often difficult to justify
  • Regression testing services take time to complete

Regression testing and its value aren't sufficiently visible to test teams, developers, and management.

What are the stages of regression testing services?

We at Relevant follow a straightforward and clearly defined regression testing workflow. First, we describe a well-defined tracing matrix: requirements and test cases. Then we follow dependency evaluation, release the regression testing package, and vulnerability analysis.

Below, we summarize how the regression testing process works at the regression testing company.

  1. Review project schedule
  2. Define the test plan
  3. Development of test cases
  4. Conduct testing
  5. Log defects
  6. Report the results
  7. Test the system again
What is the best time to take regression testing service?

We offer you to provide regression testing service after testing changes or new features. But this isn't always the case.

Regression testing is retesting (which means repeating the test). When retesting, the reason can be any. It depends on what you need to test and at what stage of development. Below are some of the most common regression testing scenarios:

  • Carrying out test cases with frequent defects
  • Testing of user functionality
  • Checking the key characteristics of the product
  • Testing integration tests
