Passing in test files to CLI should be matched against relative path

[brandon-leapyear]

🚀 Feature Proposal

When running jest foo, foo should be matched against the path relative to package.json instead of its absolute path.

Motivation

We have a test file user.spec.ts, and accidentally running jest user runs all tests, because the full path of all the test files starts with /Users/my-username/.... It's also odd to run jest foo and not see the string "foo" anywhere in the output

$ jest test /Users

RUNS src/index.spec.ts
RUNS src/author.spec.ts
RUNS src/book.spec.ts

Example

Pitch

This oddity is confusing behavior that should at least be documented. The current documentation says

When you run jest with an argument, that argument is treated as a regular expression to match against files in your project.

which is confusing if the regular expression can also match directories outside of my project. I can't think of a good reason to keep this behavior (why would you want a regex matching all of the test files in your project?)

To be fair, Jest at least consistently does this (resolving to absolute paths) pretty much anywhere we use paths.
I regularly use it to match only a test.js I've created in the root by including the project directory name (jest my-project/test.js) however this could also be achieved in relative path matching.
I would say #7185 is the place to do such a change if we want if that ever happens - if we switch all paths to glob matching by default, those globs can also be relative to the cwd in CLI arguments, or root dir in config files.

I still think this would be good to fix

I'd honestly consider this a bug. We need to work if you pass an absolute path, but we should probably special case absolute paths instead. Matching on patterns outside of rootDir is just weird.

Is this something you'd be willing to work on?
