Grunt-Mocha `PhantomJS timed out`

I keep getting this message while runnign my mocha tests from grunt.

Warning: PhantomJS timed out, possibly due to a missing Mocha run() call. Use --force to continue.

The tests ran fine in the browser, however they fail to start from grunt. I've been using this Grunt plugin for running my brower tests , and my this is the relevant parts of my Gruntfile.js.

// I've checked if it does server while my tests are running & it does
connect: {
  test: {
    // public is where all my files are, of course
    base: 'public', 
    port: 8080
  }
},

mocha: {
  client: {
    urls: ['http://0.0.0.0:8080/test.html'],
    log: true,
  }
},

Here's the test.html file

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Mocha Tests</title>
    <link rel="stylesheet" href="css/mocha.css" />
  </head>
  <body>
    <div id="mocha"></div>
    <script src="js/test.js"></script>
    <script>mocha.run();</script>
  </body>
</html>

Here's the public directory

/public
- index.html
- test.html
 /css
  - main.css
  - mocha.css
 /js
  - main.js
  - test.js \\ contains main.js + mocha.js + my tests

Here's the output from grunt following up to the fail.

Running "uglify:dev" (uglify) task
File public/js/main.js created.
File public/js/test.js created.

Running "connect:test" (connect) task
Started connect web server on http://0.0.0.0:8080

Running "mocha:client" (mocha) task
Testing: http://0.0.0.0:8080/test.html

Warning: PhantomJS timed out, possibly due to a missing Mocha run() call. Use --force to continue.

Aborted due to warnings.

All the src I need for the tests is put in a single file it includes my source (and it's dependencies), mocha, and the tests.

Don't know if it is still relevant to you, but just in case anyone else faces this issue: In my case, the tests worked perfectly fine if I directly called them from command line, like: mocha-phantomjs .\test\src\tests.html. It was only that grunt-mocha was unable to run them, throwing this error. Shifting to grunt-mocha-phantomjs fixed it for me, no code change required. Gruntfile looks like this:

mocha_phantomjs: {
    all : ["./test/**/*.html"]
}

(You may have to escape that property name if you have set camelcase to true in your jshint settings though.)

mocha.run() only works when running tests in the browser.

To run tests in the browser and grunt do this:

Replace mocha.run() with:

if (window.mochaPhantomJS) {
    mochaPhantomJS.run();
}
else {
    mocha.run();
}
