Generating coverage for files passed in `--findRelatedTests`, `--onlyChanged` and `--watch` scenarios #5601

stipsan · 2018-02-18T03:16:38Z

I used #4246 as base. But being a bit unhappy with introducing another cli flag I ventured into testing if it's possible to instead use --coverage in combination with the flags we already have, like --findRelatedTests.

There's attached test cases for --findRelatedTests foo.js --coverage and --onlyChanged --coverage. I will add more but I thought it's a good time to get your feedback before I do that, since I'm very unhappy with some parts of how I solved it and would love to get some pointers (for instance on how to deal with _replaceRootDirInPath).

Btw this changes the behavior seen in #2256 to this:

@stipsan in theory it should pass in windows now. At least it does on a virtual machine.

No way to use slash instead of this regex?

It only worked for one of them:

Looking at slash source, it's because the text contains non-ascii chars https://github.com/sindresorhus/slash/blob/master/index.js#L10

The test above uses expect(stderr).toMatch(/PASS __tests__(\/|\\)file2.test.js/); insead of snapshot, might be a better idea

Agreed, it's enough to see what's going on.

I agree the snapshots is not necessary here.

IMO all we need to know is these two assertions:

({stdout} = runJest(DIR)); expect(stdout).toMatch('b.js'); ({stdout} = runJest(DIR, ['-o'])); expect(stdout).not.toMatch('b.js');

Do you agree? That should work just as well on windows as *nix 😄

I'm down with that

This should be renamed to replaceRootDirInPath, as underscore implies "private" method, which it's not now :D

You're right 😄

We're going polymorphic here, let's just set collectCoverageFrom to undefined by default

Or empty array, whatever is easier

Yeah sure 👍

SimenB · 2018-02-19T07:27:10Z

Could you add some unit tests to the new code introduced? Might be difficult with run_jest, but at least the new code in jest-config should be possible.

You can use your new fancy flag to check the coverage without running the full suite! 😀 See post above from codecov with diff against master

stipsan · 2018-02-20T12:15:56Z

Yes sure, I have free time later today 😄

Haha yeah, very meta 😂 Using the new flag to help test the… new flag 🧠

stipsan · 2018-02-22T22:26:21Z

not sure why codecov marks those lines as untested, locally they're tested.

I looked into run_jest and without much prior art to go on I have to try again over the weekend.

Also, I noticed the coverage scoping doesn't work with the filematch and testname matching modes in the watcher. I'll update those as well over the weekend and I think that should cover our bases 😄

stipsan · 2018-03-14T00:21:18Z

Ok I'm back from the dead (manflu is no joke), I'll dig head first into how I can test run_jest properly and beat the final boss 🐲
