CI/CD Testing: Complete Guide To Continuous Testing (2026)

CI/CD testing is the practice of running automated tests throughout a Continuous Integration and Continuous Delivery (CI/CD) pipeline to validate every code change before deployment. By automating unit, integration, API, and end-to-end tests, teams can catch bugs early, improve code quality, and release software faster with confidence.

@keploy Stop Mocking APIs Manually | Use Digital Twin Sandboxes and Find Regressions in CI Quickly

Your developers — and your AI agents — need a safe way to test against production-like behavior. Keploy records real API traffic and replays it as a digital twin sandbox, so you can catch regressions before they ship. No manual mocks. No production access. No complex test environment setup. Record → generate tests and mocks → replay in CI.

Bug Life Cycle In Software Testing: Every Stage Explained (2026)

That journey is the bug life cycle, and teams that manage it well ship faster than teams that treat bug tracking as an afterthought.
