/**
* Test Parsedown against cached expect-to-pass CommonMark spec examples
*
* This test suite runs tests the same way as `test/CommonMarkTestWeak.php`,
* but uses a cached set of CommonMark spec examples in `test/commonmark/`.
* It is executed along with Parsedown's default test suite and runs various
* CommonMark spec examples, which are expected to pass. If they don't pass,
* the Parsedown build fails. The intention of this test suite is to make sure,
* that previously passed CommonMark spec examples don't fail due to unwanted
* side-effects of code changes.
*
* You can re-create the `test/commonmark/` directory by executing the PHPUnit
* group `update`. The test suite will then run `test/CommonMarkTestWeak.php`
* and create files with the Markdown source and the resulting HTML markup of
* all passed tests. The command to execute looks like the following:
*
* $ phpunit --group update
*
* @link http://commonmark.org/ CommonMark
