Could not find test files. Create one and try again

[crutchcorn]

When trying to run tests, I get the following error:

FAIL  src/__type_tests__/pick-deep.test-d.ts
  ● Test suite failed to run

    Could not find test files. Create one and try again

It seems like there isn't anything being found from mlh-tsd in findCustomTestFiles. If, after globby, I output:

    console.log({testFilesPattern, testFiles, cwd})

I get this:

{
  testFilesPattern: [
    'C:\\Users\\crutchcorn\\git\\UnicornUtter\\ts-util-helpers\\src\\__type_tests__\\pick-deep.test-d.ts'
  ],
  testFiles: [],
  cwd: 'C:\\Users\\crutchcorn\\git\\UnicornUtter\\ts-util-helpers'
}

My jest file is this:

module.exports = {
    runner: 'jest-runner-tsd',
    testMatch: ['**/*.test-d.ts'],
};

And my test is indeed in the pick-deep.test-d.ts path

I'm running Windows 11 if that helps

Thanks for report.

Most probably all got fixed in #19. I was wrestling with this error on CI. Here is the problematic line (testFiles must be globs, so slashes had to be normalised):

jest-runner-tsd/src/run.js

Line 44 in 82e6f91

testFiles: [normalizeSlashes(testFile)],

Updated code is not yet released.

You can patch the library inside node_modules to see if that helps. Or we could ask @SimenB for a release (;

That was fast! Thanks y'all!

Don't wanna open a new issue in case this is my fault for not noticing first. Is passing a project to tsd supported in the runner?

Something like this:

tsdjs/tsd#32 (comment)

[mrazauskas]

Not sure I fully understand your question. Do you try to find out if the workaround will work? It should work. The runner is just a tiny wrapper around tsd.

If something does not work, better open new issue (;

[crutchcorn]

Well, I'm admittedly not sure where to pass the second argument for said workaround 😅 to tsd (the project name) in the test runner

[mrazauskas]

Ah.. That’s more simple with the runner. There is no need to create a dummy project. Just point to an empty .d.ts file using a docblock at the top of your test file.

See docs and example (that’s not empty .d.ts, but it should work with empty one too).

Does this help?

[crutchcorn]

Oh! I read that in the docs but didn't make the connection that the two were the same. Apologies!

[mrazauskas]

@crutchcorn Version 2.0.0 is just release. It does not require any work arounds (no more docblock, etc). Just go through the readme carefully. Many details changed.

Give it a try (;
