Hi!
Shuah please consider applying to the kselftest tree.
This set is an attempt to make running tests for different sets of data easier. The direct motivation is the tls test which we'd like to run for TLS 1.2 and TLS 1.3, but currently there is no easy way to invoke the same tests with different parameters.
Tested all users of kselftest_harness.h.
v2: - don't run tests by fixture - don't pass params as an explicit argument
v3: - go back to the orginal implementation with an extra parameter, and running by fixture (Kees); - add LIST_APPEND helper (Kees); - add a dot between fixture and param name (Kees); - rename the params to variants (Tim);
v4: - whitespace fixes.
v1: https://lore.kernel.org/netdev/20200313031752.2332565-1-kuba@kernel.org/ v2: https://lore.kernel.org/netdev/20200314005501.2446494-1-kuba@kernel.org/ v3: https://lore.kernel.org/netdev/20200316225647.3129354-1-kuba@kernel.org/
Jakub Kicinski (5): kselftest: factor out list manipulation to a helper kselftest: create fixture objects kselftest: run tests by fixture kselftest: add fixture variants selftests: tls: run all tests for TLS 1.2 and TLS 1.3

Kees suggest to factor out the list append code to a macro, since following commits need it, which leads to code duplication.

Grouping tests by fixture will allow us to parametrize test runs. Create full objects for fixtures.
Add a "global" fixture for tests without a fixture.

Now that all tests have a fixture object move from a global list of tests to a list of tests per fixture.
Order of tests may change as we will now group and run test fixture by fixture, rather than in declaration order.

Each fixture will be evaluated for each of its variants.
