title: Mocha only running one test file
body: <p>My Mocha tests were working fine, but when I added a new module (and test), mocha stopped running all of my test files and now only runs the single new test.</p>
  
  <p>My test script:</p>
  
  <pre><code>env NODE_PATH=$NODE_PATH:$PWD/src mocha --recursive --compilers js:babel-core/register src/**/*.test.js --require babel-polyfill
  </code></pre>
  
  <p>My project is structured like this:</p>
  
  <pre><code>/src
    /components
      /component-name
        index.js
        component.js
        component-name.test.js
        style.scss
    /util
      /module-name
        index.js
        module-name.test.js
    /some-other-module
      index.js
      some-other-module.test.js
  </code></pre>
  
  <p>I had several tests in <code>/components</code> and <code>/util</code> and everything worked fine, but when I place a module into <code>/src</code> (like <code>/some-other-module</code>) with a <code>.test.js</code> file in it, Mocha only runs that test file and none of the others.</p>
