DifficultToTestCodeKata

A code kata which represents difficult-to-test real-world experiences

Design notes:

• All classes under unmodifiable are considered out-of-bounds for changes.

  • unmodifiable/objectFilter is intended to represent a database layer

    • query objects and methods which are difficult to mock
    • mix business logic into the database layer

  • unmodifiable/rooms is going to encapsulate state and make it difficult to mock the objects exposed.

    • how can instanceof make mocking difficult?
      • typecast to a different unrelated object?

• Add in a long convoluted method which mixes many concerns and dependencies

  • may be out of the scope of this kata
