What is regression testing, and how do you automate it with AI?

End-to-End Testing

End-to-end testing verifies a complete user journey works from start to finish, the way a real user experiences it. With AI you describe the journey as a goal and an agent carries it out – logging in, navigating, filling forms, verifying the outcome – across your whole app. QA.tech runs these in parallel and re-navigates when the UI changes, so long flows don't collapse on a renamed button.

Exploratory Testing

Exploratory testing means investigating an application to discover how it behaves and where it breaks, rather than following a fixed script. AI can do this: an agent clicks through a new or changed feature, finds the flows and edge cases, and proposes test cases for what it sees. With QA.tech this runs automatically when a feature lands.

Feature Flag & A/B Test Testing

Different users see different versions of your app, so a flow that passes for the control can fail for a variant. With AI you run the same test plan against environments configured with different flag states, verifying critical flows work regardless of which variant is active.
