"""Build conformance tests.

Steps:
- Specific input shapes (or tests) are specified and produced by using the
  settings in the .json files.
- Tests are selected to produce a good coverage.
- Tests are run on the reference model to produce the correct output files.
- Tests are converted to JSON and/or copied and saved to desired output directory.
