This is not a standard docstring.
We will explain the non-standard fixtures that pytest_generate_tests is
creating here.
silicon_arch_name and silicon_arch_<ARCH_NAME>
----------------------------------------------
This is how tests should be requesting accelerator architecture names.
Tests which aim to run on silicon should request a silicon_arch_name
fixture. Just that single fixture will parametrize the test to run on the
provided architecture name from the command line through the --tt-arch
option. The value of the fixture will be the string value of the
architecture name. For example,
@pytest.mark.post_commit
def test_model_silicon(silicon_arch_name):
# silicon_arch_name will be one of grayskull, wormhole_b0 etc.
run_model_on_silicon(silicon_arch_name)
...
If you want to restrict a test to only a specific architecture, you can
provide an additional fixture in the form of silicon_arch_<ARCH_NAME>. This
will limit the range of possible values for silicon_arch_name to only be
ARCH_NAME.
@pytest.mark.post_commit
def test_model_silicon_grayskull_only(
silicon_arch_name,
silicon_arch_grayskull,
):
# silicon_arch_name can only be grayskull or empty
run_model_on_silicon(silicon_arch_name)
...
If --tt-arch specifies an architecture that's not ARCH_NAME, the test will
be skipped. We ensure skipping by providing an empty list parametrization
for silicon_arch_name, and with the empty_parameter_set_mark config option
for pytest, will skip any tests with an empty list parametrization.
Note that you must provide silicon_arch_name as a fixture if you want to
use the silicon_arch_<ARCH_NAME> fixture.
Note that if tests want to use the ARCH value from the API, tests should
create their own separate fixture which will convert the string value
provided from silicon_arch_name into ARCH. We keep it as strings here
because these fixtures will be used in tests which do not have access to
any Python APIs.
