Regression testing services
Regression testing for reliable software updates and releases.
DeviQA provides manual and automated pencils regression testing for web, mobile, and desktop applications and APIs. Since 2010, our engineers have built, maintained, and integrated regression suites into CI/CD pipelines. Client results include reducing regression testing from 2.5 weeks to 2 hours for Abbott’s FreeStyle Libre and from 2 weeks to approximately 6 hours for ChargeAfter.

Regression testing challenges addressed by DeviQA
DeviQA turns code changes, product dependencies, and critical user journeys into targeted regression checks that help teams catch unintended effects before release.
Regression testing services provided by DeviQA
DeviQA selects the regression testing scope based on change impact, product risk, application architecture, and release size.
Corrective regression testing
We reuse existing regression test cases after code changes that do not alter the original product requirements.
Retest-all regression testing
We rerun the complete existing regression suite when a change is extensive, high-risk, or difficult to isolate.
Selective regression testing
We select regression tests based on the modified code, affected dependencies, business risk, and critical user workflows.
Progressive regression testing
We create or update regression test cases when new features or requirements change the expected behavior of the product.
Partial regression testing
We test the modified component and its connected functionality while excluding areas that are not affected by the change.
Unit-level regression testing
We rerun tests for modified functions, classes, or components in isolation before they are integrated into the wider system.
Complete system regression testing
We perform end-to-end regression across the complete system after major releases, architecture changes, platform migrations, or multiple connected updates.

DeviQA’s regression testing process
DeviQA follows a six-step regression testing process covering change-impact analysis, test planning, environment preparation, execution, defect reporting, and final validation.
Analyze changes and regression risks
We review product changes, affected dependencies, critical workflows, integrations, and previous defects to determine the required regression scope.
Define the regression test plan
We select the test cases, coverage areas, test data, environments, priorities, execution schedule, and entry and exit criteria.
Prepare the test environment
We configure the required application build, integrations, dependencies, devices, browsers, and test data in an environment aligned with production conditions.
Execute the regression scope
We execute the selected manual and automated regression tests to identify unintended effects on existing functionality and applicable non-functional behavior.
Report and prioritize regression defects
Each defect report documents the affected functionality, severity, reproduction steps, environment, expected and actual results, and supporting evidence.
Retest fixes and validate the release
We retest resolved defects and run targeted regression checks across connected functionality. The final report summarizes completed tests, open defects, coverage, and remaining release risks.
