What Happens When Regression Testing Is Missing From Your Release Cycle

Regression testing is a significant type of software testing that tests whether the existing & old functionality of a software or application is responding properly or not. The main purpose of regression is to find bugs, which were introduced accidentally while performing new modifications & changes in the system. The following are the profound effects it brings to the table.

With up to an astonishing 80% decrease in reported bugs, regression testing protects your software from bugs that occur after new releases and hampers user experience.

Regression Testing Services Tailored to Your Stack, Sprint Cycle, and Industry

At Thinksys, we employ an iterative method to test various aspects of the updated or modified software application. Our team’s skills allow us to functionally determine when to terminate testing after detecting all adhesive risks. We also have a fundamental way to stimulate the releases of systems under test (SUT). Our methods of testing are executed early in the development process, which assists us in tackling discrepancies that might occur in the software. Therefore, the various Customised regression services offered by us are:

Corrective Regression Testing

Ensures previously fixed issues remain vanquished, preventing their return and safeguarding your software from several bugs. Here, tests are conducted on the current test cases that do not have code changes.

Our Regression Testing Process

From day one to every release after, here's exactly how we work.
Regression Audit
Know what you have before you build what you need.We review your existing test suite, codebase, and release history. Every critical user path gets mapped. Every coverage gap gets prioritized. You get a clear picture of where regressions are most likely to happen before the next release exposes them.

Automated Regression Testing Services Built for Agile and CI/CD Teams

Manual regression testing doesn't scale with modern sprint cycles. Thinksys builds and maintains automated regression testing services using Selenium, Cypress, Playwright, and TestComplete integrated directly into your Jenkins, GitHub Actions, or Azure DevOps pipeline. Every PR triggers regression checks. Every release goes out with confidence. Regression testing in agile isn't a phase, it's a continuous process embedded in every sprint.

Frequently Asked Questions

Regression testing ensures that new code changes don't break existing functionality. Every release new features, bug fixes, or refactoring risks introducing defects in previously working areas. Without regression testing, teams discover these issues in production, where they cost 10–100x more to fix and directly impact users.
Regression testing services provide expert QA engineers who build, maintain, and execute regression test suites on your behalf. This includes manual and automated regression testing across functional, integration, and end-to-end layers, integrated into your CI/CD pipeline so every release is validated before it reaches production.
Regression testing reduces post-release defects, increases release confidence, and removes the fear of shipping. Engineering teams move faster when they know every new feature has been checked against the full system. Thinksys clients typically see a 70–80% reduction in production incidents within the first 90 days of engagement.
Look for CI/CD integration capability, automation framework expertise (Selenium, Cypress, Playwright), experience in your industry vertical, US timezone coverage for fast turnaround, and transparent coverage reporting. Avoid vendors who only deliver test execution reports without maintaining or improving the regression suite over time.
Regression testing services are based on specific software requirements and use a strategic approach to identify underlying issues by creating and executing test cases targeted specifically to the newly modified areas. The results are analyzed once test cases are executed, and bug tracking takes place to maintain software stability throughout the development process.
Options range from in-house QA teams using open-source frameworks (Selenium, Cypress, Playwright) to managed regression testing services like Thinksys where a dedicated qa team builds and runs your regression suite. Managed services are preferred by US engineering teams that want coverage without hiring and retaining QA headcount.
Regression testing solutions are proven to improve the testing process in the following ways:
  • Execution of test cases.
  • Faster and more frequent test cycles.
  • Comprehensive test coverage.
  • Automating repetitive tasks.
  • Improve accuracy by reducing human error.
Yes. The main challenges are test suite maintenance as the codebase grows, flaky tests that erode confidence in automation, and time pressure from fast release cycles. Thinksys addresses these with dedicated suite maintenance, flaky test triaging, and parallelized test execution that keeps regression runs under 15 minutes regardless of suite size.
Neglecting regression testing can lead to various risks and consequences for the software, such as degradation of software performance, recurrence of fixed bugs, poor user experience, and compatibility issues. The outcome of these risks can lead to loss of user trust, increase in bug fixing cost, negative impact on brand image, and rise in consumer complaints.
