Most modules on CPAN come with tests (and those which don't should). When the module is installed by the user there are four steps which should always be run on the unpacked tarball. These are:

  1. Produce the makefile or the build script
  2. Make/build the distro from the source
  3. Run the tests
  4. Install into @INC

The tests in step 3 are the ones which we're talking about here and by convention live in the top-level t/ directory. For example, here's where they are in Text::CSV_XS. You can view the results of the tests being run on a wide variety of platforms at CPAN Testers.

You can use these tests as a basis for some you run against your own code to see how it handles the various edge cases, etc.
