Ship with confidence: one system of record for manual, automated, and CI tests
Manual test cases, automated test runs, and CI pipeline results consolidate into one dashboard so there are no blind spots about coverage or pass rates.
Paste a manual test case, choose a framework, and Qase generates an automation script for Playwright, Cypress, or Selenium, shrinking the manual backlog instead of growing it.
Bidirectional links connect every requirement to its test cases and results, so when something breaks you can trace exactly what was verified.
Pass rates, coverage gaps, blockers, and flaky-test history come together in shareable readiness views for confident go/no-go decisions.
AI-powered API versioning that keeps every release number accurate and consistent.
Let the platform propose the right next version number for your API and each endpoint, reducing human error in release numbering.
Apply standard semantic (major.minor.patch) and calendar-based versioning, or define a convention that fits your organization.
Keep a traceable record of how a version evolved, who changed it and why, so audits and rollbacks are simpler.
Standardize version numbering across teams and services so API consumers always know what a given release means.
