All major parts of CodernityDB has their own test suite. We also test CodernityDB single-thread, multiple-thread (thread-safe, and super-thread-safe) and the gevent one.
There are some patch mechanizm / locks so running the test suite in wrong combination might report wrong results.
Running default test suite on your hardware will cause a lot of IO operations and intense CPU work for several minutes (depends on your hardware). Really do not run tests suite on environments with less than 4 cpu cores without clock at least 2.5GHz, also if you run SSD for personal use, use ramcache instead. Test suite performs more than 24 000 000 system calls to write, read, lseek.
For more details visit or clone our https://bitbucket.org/codernity/codernitydb and check tox.ini and pytest.ini files.
Whole test suite contains a lot of different tests, that covers naturally all database functions, and probably most of use-cases of them.
