💡 Flag methods as unused if they are only imported by their respective test files #1459
Description
Suggest an idea for Knip
We have plenty of code in our codebase that is only imported in a test file, never in production code.
Imagine isUrl.ts and then isUrl.test.ts as only occurrence where it gets imported. This correctly is not flagged by knip, but it would be helpful for us to get rid of legacy code that is "unused".
This shouldn't be default but could be supported by a flag to opt-in.
