/**
* PHPUnit tests to test the wide range of all typical use cases for formulae at Wikipedia.
* To generate the page https://www.mediawiki.org/wiki/Extension:Math/CoverageTest is used to
* generate the test data.
* The testData is generated by the maintenance script Math/maintenance/MathGenerateTests.php.
* To update the test data locally with vagrant the following procedure is recommended:
*
* 1. copy the source from https://www.mediawiki.org/wiki/Extension:Math/CoverageTest
* to a new page e.g.
* MathTest at your local vagrant instance
* 2. run <code>php MathGenerateTests.php MathTest</code>
* in the maitenance folder of the Math extension.
* 3. Test local e.g. via
* <code>sudo php /vagrant/mediawiki/tests/phpunit/phpunit.php
* /vagrant/mediawiki/extensions/Math/tests/MathCoverageTest.php</code>
* (If you don't use sudo you might have problems with the permissions set at vagrant.)
