Regression Testing

Stop Shipping API Regressions to Production

Run your full API test suite on every deployment. Self-healing tests adapt to non-breaking changes so you fix real regressions, not flaky tests.

How API regressions slip through

No regression suite

You don't have a comprehensive regression test suite for your APIs. Testing is ad-hoc or focused only on new features.

Tests are too fragile

Existing regression tests break on every minor API change. Teams spend more time fixing tests than catching bugs.

False positives everywhere

Non-breaking changes (new optional fields, updated descriptions) trigger test failures. Real regressions get lost in the noise.

Regressions found late

API regressions are caught in integration testing, staging, or production — not at the API level where they originate.

No trend visibility

You can't see if regression failures are increasing or decreasing across releases. History is lost.

Manual regression cycles

Before every release, QA runs manual regression checks. It takes days and still misses edge cases.

Why traditional regression testing breaks for APIs

API regression testing needs to be automated, comprehensive, and resilient to non-breaking changes.

!
Manual regression: Doesn't scale. Takes days before each release. Inconsistent coverage. Impossible to run on every commit.
!
Brittle scripts: Hand-written regression scripts break on cosmetic API changes. Maintaining them costs more than the bugs they catch.
!
UI-level regression: End-to-end UI tests are slow, flaky, and test too many layers at once. API-level regression is faster and more precise.
!
No regression testing: Some teams rely on production monitoring to detect regressions after they ship. By then, users are affected.

How self-healing regression testing works

1

Generate a comprehensive regression suite

AI creates tests for every endpoint from your OpenAPI spec: happy paths, error cases, edge cases, and security checks.

2

Run on every deployment

Execute the full regression suite in your CI/CD pipeline. Every push, every PR, every deployment is covered.

3

Self-healing adapts to changes

When the API spec changes, tests automatically adapt to non-breaking changes. Only real regressions trigger failures.

4

Track regression trends

See regression failure rates over time, most-affected endpoints, and test stability across releases.

Frequently asked questions

  • What are self-healing tests?
    Self-healing tests automatically adapt when your API spec changes in non-breaking ways — like new optional fields, updated descriptions, or reordered properties. You only see failures for actual regressions: removed fields, type changes, broken behavior.
  • How is this different from just re-running functional tests?
    Regression testing specifically focuses on detecting unintended changes in previously-working behavior. Self-healing ensures that intentional, non-breaking changes don't create noise. The result: every failure is a real regression worth investigating.
  • Can I run regression tests on every commit?
    Yes. The test suite runs in your CI/CD pipeline on every push, PR, or scheduled interval. Typical suites of 50-200 tests complete in 1-5 minutes.
  • What happens when a real regression is detected?
    The pipeline fails (if quality gates are configured). The platform shows which endpoints regressed, what changed, and the expected vs. actual response — giving you everything needed to diagnose and fix the issue.
  • Do I need to update tests when the API changes?
    For non-breaking changes: no, tests self-heal. For breaking changes (removed endpoints, type changes), the platform flags affected tests and suggests updates.
  • Can I see regression trends over time?
    Yes. The analytics dashboard shows regression failure rates, most-affected endpoints, and test stability trends across builds and releases.
