All tests originated from the CSS Working Group Test repository from the /approved directory. This directory contains all tests that have been reviewed and approved. Some tests have been modified to pass HTML5 parsing, or normalizing of CSS for suite testing; the essence of CSS has not been changed.
The suite of tests is normally used to validate CSS rendering in a browser. This library uses the tests to validate CSS parsing and CSS' representation in a AST to ensure valid CSS is accepted.
All enabled tests should be passing. Set current directory:
cd csslib-test-suiteTo run all suite tests:
# Make sure dependencies are installed
pub install
# Run command line tests
#export DART_SDK=path/to/dart/sdk
dart run_all.dartTo run an particular set of tests
dart suite/selectors3/selectors3_test.dartAll suite tests are run from the dart file test/suite/run_all.dart
Each CSS test is located in the src directory within the directory named for the set of tests to run. For example, the directory suite/css3-page will test the @page CSS directive. In the css3-page directory will be a src directory of the the raw files that contain HTML and/or CSS and a dart file that spins up the tests to run. In each dart file, is an _ExceptionMatches Map that maps test files to either be skipped (marked as SKIP_TEST) or matching text to validate the parsed CSS text (typically the normalizing of spaces, color values, etc.).
Disclaimer: Any test marked as SKIP_TEST has a TODO comment that will be fixed as we add more functionality (e.g., encoding, richer selector parsing and error recovery).
