Large chunks of the test suite are open source, committed to the repo and easy to run with a `make test`.

Everytime a bug is reported in the forums, the open source tests are updated as part of the bug fix for everyone to see.

There's a separate test suite that offers 100% coverage, that is proprietary, and which was created for certification for use in safety critical environments.

HN loves to discuss business models for open source, but apparently has a problem with this one. Why?
