Host tests are skipped by default #32
Description
Currently, host tests are skipped by default. For instance in Pyodide,
pytest packages/_tests/test_packages_common.py -k parse_package -v
all tests are skipped.
This is pretty dangerous and should not happen.
In particular, it even passing --rt=host produces another issue in the above command, since it looks like we did changes with this test skipped so it's now broken,
