"""L0 Tests Runner.

How to run this script?

1. Run all the tests: `python /path/to/apex/tests/L0/run_test.py` If you want an xml report,
    pass `--xml-report`, i.e. `python /path/to/apex/tests/L0/run_test.py --xml-report` and
    the file is created in `/path/to/apex/tests/L0`.
2. Run one of the tests (e.g. fused layer norm):
    `python /path/to/apex/tests/L0/run_test.py --include run_fused_layer_norm`
3. Run two or more of the tests (e.g. optimizers and fused layer norm):
    `python /path/to/apex/tests/L0/run_test.py --include run_optimizers run_fused_layer_norm`
