With the latest pytest release (3.3.0) when trying to run the tests I get the error:

Caused by pytest-metadata apparently.

Yup - see https://github.com/davehunt/pytest-metadata/issues/5

I have a similar error

@LaurianoElmiroDuarte wrong issue, you forgot a - before --pdb making it it the ``` -p db
