Test-case

A test-case is a single test that determines a specific aspect of what it is that is being tested. There are many reasons to spend time developing tests.

Testing for a developer

A proper test scenario will help a developer prevent regressions and determine if the functionality is still functioning properly in all its aspects.

Testing for users of MediaWiki

A proper test set will help a user of MediaWiki or a hosting company to determine if a particular extension but also version of an extension is safe to run on a production wiki. Tests may also be developed to determine if specific functionality exists.
