/* Testcases for CSS Unprefixing service.
|
|
*
|
|
* Each testcase MUST have the following fields:
|
|
* - decl: A CSS declaration with prefixed style, to be tested via elem.style.
|
|
* - targetPropName: The name of the property whose value should be
|
|
* affected by |decl|.
|
|
*
|
|
* And will have EITHER:
|
|
* - isInvalid: If set to something truthy, this implies that |decl| is
|
|
* invalid and should have no effect on |targetPropName|'s
|
|
* computed or specified style.
|
|
*
|
|
* ...OR:
|
|
* - expectedDOMStyleVal: The value that we expect to find in the specified
|
|
* style -- in elem.style.[targetPropName].
|
|
* - expectedCompStyleVal: The value that we expect to find in the computed
|
|
* style -- in getComputedStyle(...)[targetPropName]
|
|
* If omitted, this is assumed to be the same as
|
|
* expectedDOMStyleVal. (Usually they'll be the same.)
