From the repository root, use python -m tests to run tests.

Options:

• --all runs all tests (default if no other options given)
• --unit run unit tests only, skip BASIC tests
• --fast skip slow tests
• --coverage track coverage
• --loud show standard output
• --reraise re-raise unexpected exceptions to see traceback

Utilities for BASIC tests:

• python -m tests.show <category>/<testname> show output differences in failed test
• python -m tests.make <category>/<testname> create a new BASIC test
• python -m tests.model <category>/<testname> use DOSBox to (re)create the output model for a test
