title: VueCLI / Node inspect finds no test on windows host while container can
body: <p>I am trying to enable step by step debugging of a JEST unit test. I have two approaches - on the windows host and in a ubuntu docker container.
  Ubuntu container</p>
  <pre><code>node ./node_modules/@vue/cli-service/bin/vue-cli-service.js test:unit -- ./path/to/file.spec.ts
  </code></pre>
  <p>runs the test successfully.</p>
  <p>On windows host:</p>
  <pre><code>node ./node_modules/@vue/cli-service/bin/vue-cli-service.js test:unit -- .\path\to\file.spec.ts                             
  No tests found, exiting with code 1
  Run with `--passWithNoTests` to exit with code 0
  In C:\Users\HrabeT\Work\Plates\frontend
    266 files checked.
    testMatch: **/tests/unit/**/*.spec.[jt]s?(x), **/__tests__/*.[jt]s?(x) - 4 matches
    testPathIgnorePatterns: \\node_modules\\ - 266 matches
    testRegex:  - 0 matches
  Pattern: .\path\to\file.spec.ts - 0 matches
  </code></pre>
  <p>Same node version in container and on host. My aim is to debug the test step by step with <code>node inspect</code> but I can not get the host chrome to connect to the container session so I am trying to run it on the host. Yet it fails with understanding the file?</p>
  <p>My tests are in <code>./tests/unit/path/to/file</code> and here is the jest config</p>
  <pre><code>  2 module.exports = {
    3   preset: &quot;@vue/cli-plugin-unit-jest/presets/typescript-and-babel&quot;,
    4   moduleNameMapper: {
    5     &quot;^@/(.*)$&quot;: &quot;&lt;rootDir&gt;/src/$1&quot;,
    6   },
    7   transformIgnorePatterns: [&quot;/node_modules/&quot;],
    8   // setupFiles: [
    9   //   &quot;./tests/unit/setup.ts&quot;,
   10   // ],
   11 };
  </code></pre>
  <p>Dont mind the paths too much, I adjusted them for reading simplicity...</p>
