thiemowmde cd4ce78d31 Make use of actual @dataProviders in tests
Instead of manually crafted $this->testCase properties.

Also make use of the dedicated PHPUnit feature to mark as test as
passed. While assertTrue( true ) is a very common hack it can be
confusing.

/**
* This test is checking the MathML generation from LaTeX by WikiTexVC.
* It creates a list of basic LaTeX statements from the supported functions
* of WikiTexVC from TexUtil.php.
*
*
* For Re-Generating the testfile in case of change of macros in texutil.json:
*
* 1. Create a new ExportedTexUtilKeys.json by running this test with the ExportKeys flag
* 2. Create a new TexUtil-Ref file from the new ExportedKeys.json file with maintenances scripts, by running such cmd:
* "php extensions/Math/maintenance/JsonToMathML.php
* /var/www/html/extensions/Math/tests/phpunit/unit/WikiTexVC/ExportedTexUtilKeys.json
* /var/www/html/extensions/Math/TexUtil-Ref.json -i 2"
* 3. If generated correctly shift the TexUtil-Ref file in its usual folder
* WIP: This currently just generates MathML with WikiTexVC, but does not do
* a comparison.
*
* @covers \MediaWiki\Extension\Math\WikiTexVC\TexVC
