There's a lot of cases where we try to re-run the same code with
different parameters. We currently need to either use a generator
method or create a "main" case implementation which then gets called
by trivial case functions:
def _test(x, y, z):
...
def case_int():
_test(1, 2, 3)
def case_str():
_test('a', 'b', 'c')
Add support for variants, similar to kselftests_harness.h and
a lot of other frameworks. Variants can be added as decorator
to test functions:
@ksft_variants([(1, 2, 3), ('a', 'b', 'c')])
def case(x, y, z):
...
ksft_run() will auto-generate case names:
case.1_2_3
case.a_b_c
Because the names may not always be pretty (and to avoid forcing
classes to implement case-friendly __str__()) add a wrapper class
KsftNamedVariant which lets the user specify the name for the variant.
Note that ksft_run's args are still supported. ksft_run splices args
and variant params together.
