## 32.4. TAP Tests

Various tests, particularly the client program tests under `src/bin`, use the Perl TAP tools and are run using the Perl testing program `prove`. You can pass command-line options to `prove` by setting the `make` variable `PROVE_FLAGS`, for example:

    make -C src/bin check PROVE_FLAGS='--timer'

See the manual page of `prove` for more information.

The `make` variable `PROVE_TESTS` can be used to define a whitespace-separated list of paths relative to the `Makefile` invoking `prove` to run the specified subset of tests instead of the default `t/*.pl`. For example:

    make check PROVE_TESTS='t/001_test1.pl t/003_test3.pl'

The TAP tests require the Perl module `IPC::Run`. This module is available from CPAN or an operating system package.
