Develop a plan for expand test coverage

[ion-oset]

Test coverage for data models is hampered by the fact that all properties declared at class level are always run. Coverage is shown at 100% but none of those properties have actually been tested. Devising full testing for all models by hand is a large amount of work that has to be done manually, with very little immediate benefit.

Possible solutions to consider:

• Generate the test code using a generator in the same way models are generated. This is also a fair amount of work but could pay off in the long run.
• Focus on developing the test data to cover real cases.
  • Include deliberately broken or pathological models.
• Generate the test data with randomized inputs via fuzz-testing or (ideally) property based testing.
  • ⭐ Make use of Hypothesis
