Hello, ask Compete, Inc. for a test key that can be shared with the world under public automated testing. If you get one, simply include it in your tests.
Failing that, come to terms with the fact that CPAN testers will be of limited usefulness to you. Rework the interface to also accept a file to read the key from. Document this. If the file does not exist, skip all tests that depend on the key. (This similar to how I did it for Yahoo::Photos.) You will only get test results which thoroughly exercise your module's functionality from the users who set up the key file and made a report. In any case give hints in the README file and TAP diagnostics that a better result can be achieved when a tester takes the extra setup step.
