Regression intelligence

Turn API diffs into focused test plans.

APIDiff AI translates breaking changes into regression priorities, so QA and engineering can validate the right scenarios before launch.

Risk scoring Test focus lists Release readiness

High risk /checkout, /billing/invoices
Medium risk /refunds, /subscriptions
Low risk /health, /status
Coverage gap Missing tests for currency

Risk scoring matrix

Understand severity across endpoints, SDKs, and downstream integrations.

Contract break Schema or type change affecting clients
Behavior change Different status values or default behavior
Dependency shift New downstream requirements or auth scopes
Migration effort Estimated time and owners needed

Test plan builder

Automatically generate QA checklists that align with release risk.

Critical flows

  • Payment success callback
  • Invoice list pagination
  • Status mapping for settled

SDK validation

  • Billing.fetchInvoices() response
  • Checkout payload includes currency
  • Retry behavior on 409

Edge cases

  • Legacy status mapping
  • Currency default fallback
  • Partial payment reconciliation

Coverage signals

Regression recommendations are tied to real usage patterns and risk levels.

Traffic weighting

Prioritize tests for endpoints with the highest call volume.

Dependency mapping

Detect indirect impact on services that consume the API.

Release gating

Block rollout until high risk scenarios are validated.
