Today I spent maybe more than an hour tracing a bug that a screen I created turned inaccessible after a merge, tests died suddenly.

It turned out to be multiple cases, one was that a colleague changed a default export to a named one which excluded my screen. Another was an in an unrelated test which missed a React context wrapper so I needed to refactor her tests.

I don't know what kind of magic debugging tool would help with these kinds of things.
