Rework checks for unit tests

[drbscl]

• Checks for individual test methods, named as TestClass.testMethod.
• Can be automatically generated through test discovery, though again for individual tests, not entire classes as they are currently implemented.
• Weights for generated tests should be split according to the test class.
  • e.g. a test class with 4 tests will yield checks with weights of 0.25 for each individual test.
