  // Tests the calculation of the repeat duration which is one of the steps
  // towards determining the active duration.
  //
  // The repeat duration is determined by the following three attributes:
  //
  // dur:         may be definite (e.g. '2s') or 'indefinite' (the default)
  // repeatCount: may be definite (e.g. '2.5'), 'indefinite', or not set
  // repeatDur:   may be definite (e.g. '5s'), 'indefinite', or not set
  //
  // That leaves 18 combinations to test.
  var testCases =
    [
      // 1. repeatDur: definite, repeatCount: definite, dur: definite
      // (Two test cases here to ensure we get the minimum)
      { repeatDur: 15, repeatCount: 2, dur: 10, result: 15 },
      { repeatDur: 25, repeatCount: 2, dur: 10, result: 20 },
      // 2. repeatDur: indefinite, repeatCount: definite, dur: definite
      { repeatDur: 'indefinite', repeatCount: 2, dur: 10, result: 20 },
      // 3. repeatDur: not set, repeatCount: definite, dur: definite
      { repeatCount: 2, dur: 10, result: 20 },
      // 4. repeatDur: definite, repeatCount: indefinite, dur: definite
      { repeatDur: 15, repeatCount: 'indefinite', dur: 10, result: 15 },
      // 5. repeatDur: indefinite, repeatCount: indefinite, dur: definite
      { repeatDur: 'indefinite', repeatCount: 'indefinite', dur: 10,
        result: 'indefinite' },
      // 6. repeatDur: not set, repeatCount: indefinite, dur: definite
      { repeatCount: 'indefinite', dur: 10, result: 'indefinite' },
      // 7. repeatDur: definite, repeatCount: not set, dur: definite
      { repeatDur: 15, dur: 10, result: 15 },
      // 8. repeatDur: indefinite, repeatCount: not set, dur: definite
      { repeatDur: 'indefinite', dur: 10, result: 'indefinite' },
      // 9. repeatDur: not set, repeatCount: not set, dur: definite
      { dur: 10, result: 10 },
      // 10. repeatDur: definite, repeatCount: definite, dur: indefinite
      { repeatDur: 15, repeatCount: 2, dur: 'indefinite', result: 15 },
      // 11. repeatDur: indefinite, repeatCount: definite, dur: indefinite
      { repeatDur: 'indefinite', repeatCount: 2, dur: 'indefinite',
        result: 'indefinite' },
      // 12. repeatDur: not set, repeatCount: definite, dur: indefinite
      { repeatCount: 2, dur: 'indefinite', result: 'indefinite' },
      // 13. repeatDur: definite, repeatCount: indefinite, dur: indefinite
      { repeatDur: 15, repeatCount: 'indefinite', dur: 'indefinite',
        result: 15 },
      // 14. repeatDur: indefinite, repeatCount: indefinite, dur: indefinite
      { repeatDur: 'indefinite', repeatCount: 'indefinite', dur: 'indefinite',
        result: 'indefinite' },
      // 15. repeatDur: not set, repeatCount: indefinite, dur: indefinite
      { repeatCount: 'indefinite', dur: 'indefinite', result: 'indefinite' },
      // 16. repeatDur: definite, repeatCount: not set, dur: indefinite
      { repeatDur: 15, dur: 'indefinite', result: 15 },
      // 17. repeatDur: indefinite, repeatCount: not set, dur: indefinite
      { repeatDur: 'indefinite', dur: 'indefinite', result: 'indefinite' },
      // 18. repeatDur: not set, repeatCount: not set, dur: indefinite
      { dur: 'indefinite', result: 'indefinite' }
    ];

  // We can test the repeat duration by setting these attributes on animation
  // 'a' and checking the start time of 'b' which is defined to start when 'a'
  // finishes.
  //
  // Since 'a' has no end/min/max attributes the end of its active interval
  // should coincide with the end of its repeat duration.
  //
  // Sometimes the repeat duration is defined to be 'indefinite'. In this case
  // calling getStartTime on b will throw an exception so we need to catch that
  // exception and translate it to 'indefinite' as follows:
  function getRepeatDuration() {
    try {
      return $('b').getStartTime();
    } catch(e) {
      if (e.name == "InvalidStateError" &&
          e.code == DOMException.INVALID_STATE_ERR) {
        return 'indefinite';
      } else {
        ok(false, "Unexpected exception: " + e);
        return null;
      }
    }
  }

  // Animation doesn't start until onload
  SimpleTest.waitForExplicitFinish();
  window.addEventListener("load", runTests);

  // Run through each of the test cases
  function runTests() {
    ok($('svg').animationsPaused(), "should be paused by );

    testCases.forEach(function(test) {
      var a = $('a');

      // Set the attributes
      var msgPieces = [];
      [ 'repeatDur', 'repeatCount', 'dur' ].forEach(function(attr) {
        if (typeof test[attr] != "undefined") {
          a.setAttribute(attr, test[attr].toString());
          msgPieces.push(attr + ': ' + test[attr].toString());
        } else {
          a.removeAttribute(attr);
          msgPieces.push(attr + ': ');
        }
      });
      var msg = msgPieces.join(', ');

      // Check the result
      is(getRepeatDuration(), test.result, msg);
    });

    SimpleTest.finish();
