We should have some reftests for using variables in external style sheets, to support the new "CSS3 variables" feature.

Thanks for the tests.  r=me with the change below.

Can you put the var-a declaration in an external style sheet?  I think we should be testing that the tokens from the external style sheet get interpreted as a url() and resolved against the base URL of the style sheet where you use it (i.e., the local style sheet here that declares background-image).

Also that external style sheet should be in the supports/ directory, so that the base URL is different.

updated tests

Oh, I'm sorry.  I forgot the external variable was referenced from the mochitest rather than a reftest.  So I think it would be better to put it off a subdirectory of layout/style/test/.  You can call that directory "support" too.  r=me if you move it there, and then I don't need to see the patch again before it lands.

Backed out for bustage. Please make sure this at least compiles locally before requesting checkin. A green Try run would be even better.
Mihaela will you look into this?

I'm not sure what I'm supposed to do for this. I get no errors when building the mozilla-central source + my tests locally (with ./mach build).
I don't have access (yet) to build on Try.
What else should I try?

I don't think you need to do those changes.  Also, test_variables.html refers to external-variable-url.css, which should be supports/external-variable-url.css (it needs to be in a different directory for the test to make sense, as we're testing how URLs are resolved) and that file appears to be missing from the patch.

There were a few things that were causing the test to fail:

1. The background-image property needed to be set in the document itself, with the variable set in the external style sheet.

2. Some Makefile changes were needed to cause external-variable-url.css to be copied into the right place in the test environment.  (And using MOCHITEST_FILES won't do, since that only copies files into layout/style/test/; it won't keep things in subdirectories.)

3. The <link> element needed to be inserted into the document after the pref has been set, just like all the <style> elements are populated after the pref has been set.

r?gps for the change.

Ted is currently neck deep converting mochitests to use .ini manifests. I wouldn't be surprised if he's already bit rotted this patch.

Deferring to him for review.

Hint: He'll probably tell you to move things to support-files in an .ini file.

Nope. You just want to stick this in mochitest.ini nowadays:

support-files =

will do what you want.

This added a bunch of reftests without adding those tests to the reftest.list, which means they're not being run.  The tests should be added, right?

Good catch.
