Test case automation for regression

[Nevakanezah]

The plugin has several core use cases that are arduous to test properly, and verifying regression only becomes more difficult as development advances. Automating unit & integration tests is not only valuable, it's all but necessary to test many of these cases in a respectable way.
A prospective list of test cases to automate includes:

• Foal attributes use new breeding formula, and fall within expected ranges (from Confirm child attributes are generated within configured range #5)
• CRUD cases for entries in HorseList (spawn, death, onUnload, etc)
• Setting parent names
• Horses.dat read/write integrity
• Inbreeding handling
• Secret horse handling
• Gender ratio
• Command output
• Input validation, in config file and otherwise
• Impact of config options

Create automated tests to validate the behaviour of key use cases like these.

An OSS utility exists for bukkit test automation that may make this process much easier - https://github.com/seeseemelk/MockBukkit, a Bukkit mocking framework that could measurably cut down on how much mock object invocation I'll require.
