We natively handle API and DB calls.

This is a bit tricky. We run the same test multiple times, and ignore the changing fields.

We anonymise *any* private data before storing it for replay.

We capture auth headers, and mock auth server responses.

Currently yes. APIs can be easily tested. Tests for function calls will require user configuration.

Thanks, they are great answers. I think as always you can’t expect to magically throw a test tool at the application. You need some effort to make it testable. Moving out auth and anything else stateful to another service that can be mocked helps.
