[PATCH nft 2/2] tests/shell: add "--quick" option to skip slow tests (via NFT_TEST_SKIP_slow=y)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



It's important to run (a part) of the tests in a timely manner.
Add an option to skip long running tests.

Thereby, add a more general NFT_TEST_SKIP_* mechanism.

This is related and inverse from "NFT_TEST_HAVE_json", where a test
can require [ "$NFT_TEST_HAVE_json" != n ] to run, but is skipped when
[ "$NFT_TEST_SKIP_slow" = y ].

Currently only NFT_TEST_SKIP_slow is supported. The user can set such
environment variables (or use the -Q|--quick command line option). The
configuration is printed in the test info.

Tests should check for [ "$NFT_TEST_SKIP_slow" = y ] so that the
variable has to be explicitly set to opt-out. For convenience, tests can
also add a

    # NFT_TEST_SKIP(NFT_TEST_SKIP_slow)

tag, which is evaluated by test-wrapper.sh. Or they can run a quick, reduced
part of the test, but then should still indicate to be skipped.

Mark 8 tests are as slow, that take longer than 5 seconds on my machine.
With this, a parallel wall time for the non-slow tests is only 7 seconds
(on my machine).

The ultimate point is to integrate a call to "tests/shell/run-tests.sh"
in a `make check` target. For development, you can then export
NFT_TEST_SKIP_slow=y and have a fast `make check`.
