After refreshing my mind on the AST-rewriting code again -that's always
tricky- I think you have been looking into the wrong direction. I
believe something as simple as this might do:
def test_foo():
assert myfunc(42)
def myfunc(*args):
__tracebackhide__
if not args:
pytest.fail('Hello there\nLook, a multi-line message')
raise AssertionError('multi\nline') # alternative, never gets here
return True
Does this solve your usecase?
Cheers,
Floris
