testPathDirs 0 matches on windows

[dskgry]

I just upgraded from jest 14.1.0 to jest 15.0.2 and now no tests are found anymore - the testPathDir never matches anything (I tried different variations). Output is:

No tests found
41 files checked.
testPathDirs: C:\Users\dskgry\app\src - 0 matches
testRegex: tests/.*Test.js - 9 matches
testPathIgnorePatterns: \node_modules\ - 41 matches

Debug file attached.

Thanks in advance

Same, it seems to only find my real module files, not the files in my __tests__ directory.

Same, only works in v14.1.0

Can someone provide a repository that I can install on windows to test this? Seems like 15 works on windows but you have a configuration that isn't quite compatible.

Here's the repro: https://github.com/ManuelDeLeon/jest-issue-1551

It only has 2 files:

package.json

{
  "name": "jest-issue-1551",
  "version": "1.0.0",
  "scripts": {
    "test": "jest"
  },
  "devDependencies": {
    "jest-cli": "^15.0.0"
  },
  "jest": {
    "testRegex": "\\.test\\.js$",
    "testPathDirs": [
      "src"
    ]
  }
}

src\some.test.js

describe('Test', () => {
  it('works', () => {
    expect(true).toBe(true);
  });
});

With v14:

C:\MyFiles\React\repros\jest-issue-1551>npm test

> jest-issue-1551@1.0.0 test C:\MyFiles\React\repros\jest-issue-1551
> jest

Using Jest CLI v14.1.0, jasmine2, babel-jest
 PASS  src\some.test.js (0.73s)
1 test passed (1 total in 1 test suite, run time 1.706s)

With v15:

C:\MyFiles\React\repros\jest-issue-1551>npm test

> jest-issue-1551@1.0.0 test C:\MyFiles\React\repros\jest-issue-1551
> jest

No tests found
  1 file checked.
  testPathDirs: C:\MyFiles\React\repros\jest-issue-1551\src - 0 matches
  testRegex: \.test\.js$ - 1 match
  testPathIgnorePatterns: \\node_modules\\ - 1 match

The dash in testPathDirs is the issue here.

From my ticket...

Bug

Version

Jest 15.1.0
Node v4.4.7
NPM 3.10.6
Windows 10

Current behavior

Since the update to Jest 15, no more tests are found.

Steps to reproduce

• Reproducible on any project with Jest.

• Add a dash in your path, e.g. C:\idea\myproject replaced to C:\idea\my-project

• Then execute npm test.

  No tests found
  ...
  testPathDirs: C:\idea\my-project - 0 matches
  

Expected behavior

The tests are found.

Debug mode

Here is the relevant info...

  "testPathDirs": [
    "C:\\idea\\my-project"
  ]

The dash is not escaped.

Note

Probably related to this pull request...

Is it resolved? I'm facing the same problem...

Thanks for the repros. @Daniel15 is our resident windows expert. We are hoping to have a fix for this sometime tomorrow. Please be patient, it's a bit hard sometimes to keep up.

[Daniel15]

I'll try to take a look at this tonight. All the known issues should have been resolved by #1463, I'll need to investigate further and determine what broke.

Unfortunately we don't have automated builds on Windows yet. Currently, several of Jest's unit tests are broken on Windows. We're aiming to fix all those issues and enable an AppVeyor build (#1465) to more easily catch Windows-specific regressions in the future.

[Daniel15]

I think @cpojer is right that #1574 should fix this. So far I've only been able to replicate the issue for folder names containing hyphens.

Published 15.1.1 with a fix. Sorry for the wait!
