Running the phpunit test suite from core as:
php test/phpunit/phpunit.php --testsuite extensions
Yields:
PHPUnit_Framework_Exception from line 144 of vendor/phpunit/phpunit/src/Framework/TestSuite.php:
Class "Structure" does not extend PHPUnit_Framework_TestCase.

#8 {main}The reason is tests/phpunit/suite.xml defines a structure testsuite and PHPUnit attempts to load a class named structure, if such a class exists, it then asserts it is actuall a testcase class.
The problem is that WikiLexicalData defines a Structure class:
OmegaWiki/Attribute.php:60:class Structure {And thus there is a clash. A good way to fix it would be to add namespace in WikiLexicalData.
