title: mocha init timeout with mocha-phantomjs
body: <p>I have the following <code>testrunner.html</code>:</p>
  
  <pre><code>&lt;html&gt;
    &lt;head&gt;
      &lt;title&gt;Specs&lt;/title&gt;
      &lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8"&gt;
      &lt;link rel="stylesheet" href="/content/css/mocha.css" /&gt;
      &lt;script&gt;
          function assert(expr, msg) {
              if (!expr) throw new Error(msg || 'failed');
          }
      &lt;/script&gt;
  
      &lt;script src="/client/lib/require.js" type="text/javascript" data-main="/client/specs/_runner.js"&gt;&lt;/script&gt;
  
    &lt;/head&gt;
    &lt;body&gt;
      &lt;div id="mocha"&gt;&lt;/div&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>The <code>_runner.js</code> looks like this:</p>
  
  <pre><code>// Configure RequireJS
  require.config({
      baseUrl: '/client',
      urlArgs: "v=" + (new Date()).getTime()
  });
  
  // Require libraries
  require(['require', 'lib/chai', 'lib/mocha'], function (require, chai) {
  
      // Chai
      assert = chai.assert;
      should = chai.should();
      expect = chai.expect;
  
      // Mocha
      mocha.setup('bdd');
  
  
      // Require base tests before starting
      require(['specs/stringcalculator.specs'], function (person) {
          mocha.setup({ globals: ['hasCert'] });
          // Start runner
          if (window.mochaPhantomJS) {
              mochaPhantomJS.run();
          }
          else { mocha.run(); }
      });
  
  });
  </code></pre>
  
  <p>The <code>StringCalculator.specs.js</code> is this:</p>
  
  <pre><code>define(['app/model/StringCalculator'], function () {
  
      describe("StringCalculator", function () {
  
          describe("when an empty string is passed in", function () {
              it("returns 0", function () {
                  var result = StringCalculator.add("");
                  assert(result === 0);
              });
          });
  
          describe("when a number is passed in", function () {
              it("returns the number", function () {
                  var result = StringCalculator.add("2");
                  assert(result === 2);
              });
          });
  
          describe("when string is passed in", function () {
              it("returns NaN", function () {
                  var result = StringCalculator.add("a");
                  assert(isNaN(result));
              });
          });
  
          describe("when '1,2' is passed in", function () {
              it("returns 3", function () {
                  var result = StringCalculator.add("1,2");
                  assert(result === 3);
              });
          });
      });
  });
  </code></pre>
  
  <p>And this is the <code>StringCalculator.js</code> itself (from the mocha samples):</p>
  
  <pre><code>define([], function() {
      window.StringCalculator = StringCalculator = {
          add: function(inputString) {
              if (inputString === '') {
                  return 0;
              }
  
              var result = 0;
              var inputStrings = inputString.split(',');
  
              for (var i = 0; i &lt; inputStrings.length; i++) {
                  result += parseInt(inputStrings[i]);
              }
  
              return result;
          }
      }
  });
  </code></pre>
  
  <p>When running the specs in a browser calling <code>testrunner.html</code>, everything works as expected.
  When running <code>mocha-phantomjs client/specs/testrunner.html</code> on OS X, I get the following error:</p>
  
  <p><code>Failed to start mocha: Init timeout</code></p>
  
  <p>What may I'm missing here?</p>
  
  <p>I also tried <code>mocha-phantomjs http://httpjs.herokuapp.com</code> which fails with the same error.</p>
  
  <p>Update:
  If I'm calling <code>mocha-phantomjs http://localhost:81/client/specs/testrunner.html</code> I also get the following error on the console:</p>
  
  <pre><code>RangeError: Maximum call stack size exceeded.
  
  http://localhost:81/client/lib/chai.js?v=123423553533535:2601
  Failed to start mocha: Init timeout
