what i usually do is to provide the to-be-unimportable module
but put e.g. "raise ImportError()" into it. Using the 'tmpdir'
and 'monkeypatch' funcargs makes it easy to do this, e.g.:
def test_unimportable(tmpdir, monkeypatch):
tmpdir.join("docutils.py").write("raise ImportError()")
monkeypatch.setattr(sys, 'path', [str(tmpdir)] + sys.path)
..call-and-assert..
