Brian Birtles db3e8ca042 Bug 948245 part 1 - Rework and test repeat duration calculation; r=dholbert
In order to implement the min attribute properly we need to distinguish between
cases where the repeat duration is less than the active duration so we can apply
the fill mode in the 'gap'. Currently the repeat duration calculation is mostly
contained in GetRepeatDuration (but is hard to make sense of) and partly
contained in the call site CalcActiveEnd. Furthermore, it does not have thorough
tests (there were some unit tests but they were never converted to mochitests).

This patch reworks the repeat duration calculation so it is contained in one
place, easier to read, and thoroughly tested.

// 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

result: '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 $('b').getStartTime();
} catch(e) {
if (e.name == "InvalidStateError" &&
e.code == DOMException.INVALID_STATE_ERR) {
return 'indefinite';
} else {
ok(false, "Unexpected exception: " + e);
return null;
}
}
}
// Animation doesn't start until onload
SimpleTest.waitForExplicitFinish();
window.addEventListener("load", runTests, false);
// Run through each of the test cases
function runTests() {
ok($('svg').animationsPaused(), "should be paused by <svg> load handler");
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 + ': <not set>');
}
});
var msg = msgPieces.join(', ');
// Check the result
ise(getRepeatDuration(), test.result, msg);
});
SimpleTest.finish();
