Feat: load referenced json config file from package.json 'jest' when it has a valid path

Summary

Currently Jest requires json config files to be in root folder of projects. Allowing to load from another path brings way to keep projects organized. That way files can be moved to another folder includind these who are only for tests

Test plan

yarn jest packages/jest-config/src/tests/resolveConfigPath.test.ts

You can use --config CLI flag to point Jest to a config file. It does work from command line or as a script in package.json: "yarn jest --config path/to/jest.config.json".

Do you have a use case there that isn’t enough?

if the path provided isn't a file, we should throw an error

Contributor Author

rafaelrabelos Aug 16, 2023

In that case, when jest key could not be resolved as a valid file path, the package.Json is assumed. That because jest key can be a path or a config object, so i need to allow that function to return for a second flow option.
I did a new test case to avoid future issues for those who changes that code. It makes sense?

That because jest key can be a path or a config object

My point is that if you in your config define "jest": "./some-path" (i.e. it is a string), and the path it resolves to is not a file, then Jest should error. Not ignore the entry.

Contributor Author

rafaelrabelos Aug 21, 2023

Nice, guess i understood the point: if path is not a config object and it is an string there is no option to it to not be a file, be a file or throw an error. Working on it for the next push commit
