Information on the format of the tests can be found in the [sanity test formats documentation](../../formats/sanity/README.md).
# To generate test sources
```bash
$ make
```
The necessary commands are in the `Makefile`, as the only target.
The generated files are committed to the repo so you should not need to do this.
# To run tests
Use the usual `pytest` mechanics used elsewhere in this repo.
# To generate spec tests (from the generated files)
Run the test generator in the usual way.
E.g. from the root of this repo, you can run:
```bash
$ make gen_random
```

This test format currently uses code generation to assemble the tests
as the current test infra does not have a facility to dynamically
generate tests that can be seen by ``pytest``.
This will likley change in future releases of the testing infra.
