NOTE: this tests are also meant to be run as PyPy "applevel" tests.
This means that global imports will NOT be visible inside the test
functions. In particular, you have to "import pytest" inside the test in order
to be able to use e.g. pytest.raises (which on PyPy will be implemented by a
"fake pytest module")
