Tips and tricks

It’s usually a good idea to add a test in tests/files/<name>.mys and execute with make test -j 8 ARGS="-k <pattern>.

Add positive and negative tests.

Build and run all tests in parallel with make test-parallel -j 8.

Build and run all tests in parallel and all examples with make -j 8.

Open htmlcov/index.html for code coverage.

make help shows a list of all available make targets.
