The folder tests contains over 50 subfolders with unit tests, and each folder verifies the behavior of the planning engine in a specific area.
The test suite is run by the runtest.py script:
runtest.py Run all tests. runtest.py --exclude not_this_test Run all tests, except the ones you choose to skip. runtest.py A B Run the tests A and B. runtest.py --debug A Run the test A, verbosely showing its output. runtest.py --help Print information on the script and its options. runtest.py --regression Run all tests, except the ones not suitable in a regression test. See the code of the script to see which tests are excluded.
You are encouraged to submit additional test cases to the test suite, wich is used to validate each new release.
