/** Test for parsing, storage, and serialization of CSS values **/

/*
|
|
* The idempotence tests here deserve a little bit of explanation. What
|
|
* we're testing here are the following operations:
|
|
* parse: string -> CSS rule
|
|
* serialize: CSS rule -> string (normalization 1)
|
|
* (this actually has two variants that go through partly different
|
|
* codepaths, which we exercise with getPropertyValue and cssText)
|
|
* compute: CSS rule -> computed style
|
|
* cserialize: computed style -> string (normalization 2)
|
|
*
|
|
* Both serialize and cserialize do some normalization, so we can't test
|
|
* for pure round-tripping, and we also can't compare their output since
|
|
* they could normalize differently. (We might at some point in the
|
|
* future want to guarantee that any output of cserialize is
|
|
* untouched by going through parse+serialize, though.)
|
|
*
|
|
* So we test idempotence of parse + serialize by running the whole
|
|
* operation twice. Likewise for parse + compute + cserialize.
|
|
*
|
|
* Slightly more interestingly, we test that serialize + parse is the
|
|
* identity transform by comparing the output of parse + compute +
|
|
* cserialize to the output of parse + serialize + parse + compute +
|
|
* cserialize.
