Reviews on

Regression testing implies extensive software testing. It is a good practice to rerun regression tests before each release, especially after significant code modifications. This way you can safeguard software quality, reduce bugs in production, and enhance customer satisfaction by maintaining a stable user experience. Since 2010, DeviQA has served companies across diverse domains such as Healthcare, FinTech, Real Estate, Cybersecurity, Retail, AdTech, and others. Our extensive expertise enables us to develop highly effective test automation solutions, speeding up your development cycles and ensuring the superior quality of your software products.

Our solutions for your regression testing challenges

We understand that regression testing can be a daunting process, often presenting unique challenges that hinder your software development lifecycle. Our team of experts is here to address these challenges, ensuring your software remains robust and bug-free.

Time-intensive regression testing

Challenge

The conventional approach to regression testing is time-consuming, which creates bottlenecks in your development timeline. Manual execution of numerous test cases covering diverse scenarios consumes valuable resources and slows down the release cycle.

Solution

Reveal the efficiency of automated regression testing. Using state-of-the-art tools and frameworks, we automate regression tests, significantly reducing testing time without compromising accuracy.

Managing test environments

Challenge

The intricacies of maintaining multiple test environments, each with specific configurations, often lead to logistical challenges. Version control issues and discrepancies between environments can result in inaccurate test results.

Solution

We simplify test environment management by implementing robust version control and configuration management systems. Our experts ensure that your test environments precisely mirror your production setup, mitigating discrepancies and providing reliable regression testing results.

Identifying regression test suites

Challenge

As your software evolves, pinpointing the right test cases for regression testing becomes a challenge. Striking the balance between comprehensive test coverage and not overwhelming your testing resources is a constant struggle.

Solution

We use intelligent test suite optimization algorithms that dynamically select and prioritize test cases based on code changes, ensuring an efficient regression testing suite. This approach lets us cover critical areas of your application while minimizing redundancy and optimizing resource consumption.

Regression testing types we perform

Corrective regression testing

Corrective regression testing is used when the software specifications remain constant, and existing tests are reused to ensure that the corrections made have not adversely affected the system.

Progressive regression testing

Progressive regression testing guarantees that elements from the previous software version remain intact in the latest version, ensuring a step-by-step validation of software changes.

Complete regression testing

Although time-consuming, complete regression testing is valuable in scenarios where numerous updates to the existing code significantly impact overall software. It comprehensively validates all aspects of the software.

Retest-all regression testing

Retest-all regression testing meticulously examines all software specifications and changes since development, aiming to pinpoint the root cause of failures in regression tests.

Selective regression testing

In the course of selective regression testing only a specific subset of existing regression tests is executed, focusing only on functionalities more likely to be affected by recent code modifications.

Partial regression testing

As a variant of selective testing, partial regression testing executes only high-priority and critical tests from the regression suite, providing a focused validation of essential functionalities.

Regression testing vs. retesting

Pay attention to the difference between these two types of software testing.

Re-testing
  • Validates that a specific issue reported in the previous test cycle has been successfully fixed.
  • Focuses on a specific test case or a small set of test cases related to the reported defect.
  • Performed as needed, mainly after a defect is fixed to confirm the resolution.
  • Uses the same or similar test data that exposed the original defect.
  • Is not automated.
Regression testing
  • Identifies new defects, regressions, or unintended side effects caused by recent code changes.
  • Checks a broad range of functionalities across the application.
  • Usually performed in every test cycle or as part of the continuous integration process.
  • Utilizes a variety of test data to ensure that code changes have not introduced unexpected issues.
  • May be automated to ensure efficient and fast test execution.

    Frequently asked questions

    faq

    FAQ

    Regression testing is comprehensive software testing, in the course of which all ins and outs of your app are thoroughly checked. As a rule regression tests are frequently rerun to ensure that recent code changes have not adversely affected previously created and well-worked features. Its purpose is to detect any new errors and verify that the previously tested functionalities still work as intended.

      Regression testing is crucial to ensure that new code changes have not introduced defects to the existing functionality. It helps maintain the stability and reliability of the application by identifying and fixing issues early in the development cycle.

        Regression testing should be executed before every release to guarantee the overall system stability.

          Regression Testing Services are beneficial for absolutely all types of applications. Whether you develop web applications, mobile apps, desktop software, or enterprise-level systems, do not hesitate to apply for our services. Any software that undergoes frequent updates or changes can benefit from regression testing.

          The duration of regression testing depends on the size and complexity of the software, as well as the extent of code changes. The timeline varies from project to project.

          Yes, regression testing can be automated to expedite the testing process and ensure quick feedback on code changes. Automation helps run repetitive test cases, allowing manual testers to focus on more complex scenarios.

          While functional testing verifies that each function of the software operates according to the requirement specification, regression testing focuses on ensuring that new code changes do not adversely impact existing functionalities.

          While the primary goal of regression testing is to ensure the stability of existing functionalities, it may also reveal performance issues related to recent code changes. However, performance testing is a special type of testing that focuses specifically on system performance.
