New issue 486: `--help` should not fail with an exception on conftest.py errors
/ handle conftest imports more gracefully/meaningful
https://bitbucket.org/hpk42/pytest/issue/486/help-should-not-fail-with-an-exception-on
Daniel Hahler:
I have just installed `pytest` globally and wanted to look at the help options,
but it failed (probably because of me being in the project directory, but
without the virtualenv activated):
There is ../../../conftest.py, which contains an import, which does not work
outside of the virtualenv.
I think py.test should be more helpful, and display its help
options/information nonetheless. It would be nice to get a warning that the
conftest.py failed to get imported/parsed on top.
This warning would be useful in the generic case also: it's hard to tell from
the Traceback that there is some conftest.py issue involved.
Traceback (most recent call last):
