  21. EarwigBot's Unit Tests
  22. This __init__ file provides some support code for unit tests.
  23. Test cases:
  24. -- CommandTestCase provides setUp() for creating a fake connection, plus
  25. some other helpful methods for testing IRC commands.
  26. Fake objects:
  27. -- FakeBot implements Bot, using the Fake* equivalents of all objects
  28. whenever possible.
  29. -- FakeBotConfig implements BotConfig with silent logging.
  30. -- FakeIRCConnection implements IRCConnection, using an internal string
  31. buffer for data instead of sending it over a socket.
