tests: Add a test for the CSS parser Tests in the parser need 1 or 2 files: 1) test.css 2) test.ref.css (optional, defaults to test.css) The test instantiates a CSS provider, loads test.css, then dumps the loaded file to test.out.css and then checks that that file matches test.ref.css. If not, it dumps a diff between those two to the log and fails. You want to run the test with --verbose to get the output dumped to stdout.
