| /* This is the helper function to run animation tests: |
| |
| Test page requirements: |
| - The body must contain an empty div with id "result" |
| - Call this function directly from the <script> inside the test page |
| |
| Function parameters: |
| expected [required]: an array of arrays defining a set of CSS properties that must have given values at specific times (see below) |
| callback [optional]: a function to be executed just before the test starts (none by default) |
| event [optional]: which DOM event to wait for before starting the test ("webkitAnimationStart" by default) |
| |
| Each sub-array must contain these items in this order: |
| - the name of the CSS animation (may be null) [1] |
| - the time in seconds at which to snapshot the CSS property |
| - the id of the element on which to get the CSS property value [2] |
| - the name of the CSS property to get [3] |
| - the expected value for the CSS property |
| - the tolerance to use when comparing the effective CSS property value with its expected value |
| |
| [1] If null is passed, a regular setTimeout() will be used instead to snapshot the animated property in the future, |
| instead of fast forwarding using the pauseAnimationAtTimeOnElement() function. |
| |
| [2] If a single string is passed, it is the id of the element to test. If an array with 2 elements is passed they |
| are the ids of 2 elements, whose values are compared for equality. In this case the expected value is ignored |
| but the tolerance is used in the comparison. If the second element is prefixed with "static:", no animation on that |
| element is required, allowing comparison with an unanimated "expected value" element. |
| |
| If a string with a '.' is passed, this is an element in an iframe. The string before the dot is the iframe id |
| and the string after the dot is the element name in that iframe. |
| |
| [3] If the CSS property name is "webkitTransform", expected value must be an array of 1 or more numbers corresponding to the matrix elements, |
| or a string which will be compared directly (useful if the expected value is "none") |
| If the CSS property name is "webkitTransform.N", expected value must be a number corresponding to the Nth element of the matrix |
