/**
 * PHPUnit tests for the Serbian language.
 * The language can be represented using two scripts:
 *  - Latin (SR_el)
 *  - Cyrillic (SR_ec)
 * Both representations seems to be bijective, hence MediaWiki can convert
 * from one script to the other.

 * @todo methods in test class should be tidied:
 *  - Should be split into separate test methods and data providers
 *  - Tests for LanguageConverter and Language should probably be separate..
