Let's assume I have some module on CPAN and tests to this module. Some test are very slow. I want to skip this slow tests if someone installs my module via CPAN. I can add something like: 
SKIP: {
  skip "You should set RUN_SLOW_TESTS to run this" unless $ENV{RUN_SLO
+W_TESTS};
  # slow test goes here
  ...
}

This makes the job. But at the same time it will be good if this slow tests will run by CPAN Testers anyway. Because here process of running the test are automated and slow tests are not so annoying as for user of my module.
So, is it a way to know that test now runs in cpantesters environment? Maybe some environment variable to check?

In reply to Detect is my test run by cpantesters by OlegG
