Default test not found if project path contains hyphens

[insin]

Seeing this running npm test in a new project created with create-react-app@0.3.0:

Any pointers as to which Jest module I should poke around in to debug this?

If I log the value of this._testPathDirPattern in jest-cli/build/SearchSource.js, I'm seeing hyphens being prefixed with a literal \:

/C:\\Users\\Jonny\\repos\\tmp\\cra\\-030\\-app/

If I remove the hypen from escapeStrForRegex in jest-util/build/index.js, the test is found:

  const escapeStrForRegex =
- string => string.replace(/[-[\]{}()*+?.,\\^$|#\s]/g, '\\$&');
+ string => string.replace(/[[\]{}()*+?.,\\^$|#\s]/g, '\\$&');
