This project contains base tests for every PostCSS CSS parser, including:
These tests are useful for any CSS parser, not just parsers within the PostCSS ecosystem.
You can iterate through all test cases using the cases.each
method:
cases = require('postcss-parser-tests');
s.each( (name, css, ideal) => {
it('parses ' + name, () => {
let root = parse(css, { from: name });
let json = cases.jsonify(root);
expect(json).to.eql(ideal);
});
This returns the case name, CSS string, and PostCSS AST JSON.
If you create a non-PostCSS parser, just compare if the input CSS is equal to the output CSS after parsing.
You can also get the path to some specific test cases using the cases.path(name)
method.
Integration tests are packed into a Gulp task:
.task('integration', function (done) {
var cases = require('postcss-parser-tests');
let parser = require('./');
cases.real(done, function (css) {
return parser(css).toResult({ map: { annotation: false } });
});
Your callback must parse CSS and stringify it back. The plugin will then compare the input and output CSS.
You can add extra sites using an optional second argument:
s.real(done, [['Browserhacks', 'http://browserhacks.com/']],
function (css) {
});
