The Essentials of Regression Testing in Software Testing

We offer expert software regression testing services, so you can launch new features confidently, knowing your core product is protected. Our team’s track record includes over 300 well-tested projects. QAwerk’s testing approach combines automated regression testing with the skill of seasoned manual testers to elevate your software quality.

When To Perform Regression Testing?

Regression testing must be carried out regularly, particularly before major software releases and after:

  • Bug fixes
  • Code changes
  • Addition or removal of features or modules
  • Patch fixes
  • Requirement changes
  • Configuration alterations

Our regression testing service helps you ensure that recent changes have not affected the functionality of your software or brought in any new bugs.

Our Regression Testing Process

Our QA team follows a step-by-step regression testing workflow:

  • Identifying functionalities impacted by the recent changes
  • Generating new test cases that should be added to cover the recently changed areas
  • Prioritizing test cases according to the risks posed by these changes
  • Selecting test cases for automation
  • Selecting test cases for manual regression testing
  • Executing test cases

Our regression testing services cover your entire app, including previously tested components. Because this is deep-level testing, it can take up to two weeks, depending on the platform size and test case complexity.

Our Regression Testing Services

Functional Regression Testing

We check that your core features continue to work as expected after code changes. This includes testing individual functional units as well as complex end-to-end user workflows, preventing frustrating bugs from reaching your users.

Non-Functional Regression Testing

We verify that recent changes have not degraded your application’s performance and security characteristics. QA regression testing ensures your app remains fast, scalable, and secure with every update.

Visual Regression Testing

With our visual regression testing, you’ll easily catch unintended UI changes, from misaligned buttons to font changes to broken layouts. We ensure your app looks perfect on every device, protecting your brand’s visual identity.

Integration and API Regression Testing

As your dedicated regression testing company, we validate the connections between your software modules and third-party APIs. This ensures that updates in one area don’t cause failures in another, protecting the integrity of your data flows.

Types of Regression Testing We Perform

Corrective Regression Testing

This type is used when the software’s functionality remains unchanged, but the code underneath has been refactored. In corrective regression testing, our QA team uses the existing test cases to ensure that these non-functional changes have not inadvertently introduced any bugs.

Retest-All Regression Testing

With the retest-all approach, we ensure comprehensive coverage and improved defect identification by re-running all existing tests. It’s used when there have been major changes to the codebase, significant architectural modifications, or before a major product release.

Selective Regression Testing

We use selective regression testing when a precise selection of test cases is needed, considering factors like code changes, risk assessment, or critical business functionalities. It’s perfect for time-sensitive scenarios, allowing us to focus on key changes and streamline testing efforts.

Progressive Regression Testing

QAwerk testers conduct progressive regression testing when new features are added to your app. We create new test cases to validate the new functionality and run regression tests on the existing functionality that could be impacted by the new additions.

QAwerk delivered super work. I’m happy with that. They did the regression testing really well. They helped improve our product, discovering problems during the whole development process.

As we started seeing fewer bugs, as we started seeing smoother processes, we could really start having fun conversations with our university partners. And we also saw a good, healthy, organic traffic on our sites. And that definitely made all our cross-functional team members super happy as well.
star star star star star
I would recommend QAwerk for many reasons but I think two stand out - the quick seamless onboarding experience, this is absolutely key for a team that is outsourcing something so critical as QA. But also the smart use of different communication channels - they were used effectively, with respect, with a really thoughtful mindset.

FAQ

What is the purpose of regression testing?

The primary purpose of regression testing is to guarantee product stability and quality with every release. It acts as a safety net, ensuring that new code changes don’t negatively impact existing features. Our automated regression testing services are designed to fulfill this purpose with maximum speed and reliability, protecting your user experience and enabling the fast-paced release cycles common in Agile and DevOps.

What is your approach to regression testing?

We provide software regression testing services using a strategic framework that focuses on efficiency and reducing risk. Our approach includes skilled testers with domain knowledge, a defined hierarchy, a combination of manual and automated regression testing, and a focus on selecting high-priority test cases.

At what stages in the software development cycle do you perform regression testing?

We perform software regression testing as a continuous process across the entire development lifecycle, not just as a final check. It is strategically executed after code changes, server patches, and database upgrades to identify post-deployment performance issues.

What criteria do you use to select test cases for regression testing in your software?

As a specialized regression testing services company, we base our criteria for test case selection on strategic and risk-based considerations. We focus on business requirements, priority modules, and essential features. Meticulous test case selection verifies integration points and changes, with continuous monitoring to remove outdated tests.

How is regression testing documented and reported in your software development lifecycle?

Our documentation and reporting process is powered by advanced regression testing software. This allows us to submit detailed reports that include testing specifics and recommended corrective measures. Our bug reports include videos and screenshots, focusing on essential metrics.
