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

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