[RFC PATCH] app/test: add support for skipping tests

[Thomas Monjalon]

jeudi 17 août 2023, Bruce Richardson:
> When called from automated tools, like meson test, it is often useful to
> skip tests in a test suite, without having to alter the test build. To
> do so, we add support for DPDK_TEST_SKIP environment variable, where one
> can provide a comma-separated list of tests. When the test binary is
> called to run one of the tests on the list via either cmdline parameter
> or environment variable (as done with meson test), the test will not
> actually be run, but will be reported skipped.
