Note there is no pass/fail criteria for comparison tests - this is purely for information. - **Comparison tests** will compare different methods of performing the same task. An example would be comparing 2 methods of clutter filtering. Metrics to be compared may include time and performance. Note there is no specific pass/fail criteria for comparison tests - this is purely for information. A comparison test will pass if executed successfully. Any comparison testing on input parameters for a single class will be handled in the unit test.
