Error execute tests: AttributeError: __exit__

[megetron]

Working with python 2.7 shows me exception:

'''
tests/tasks/test_tasks.py:10: in
with description('Refactoring Goodies') as self:
E AttributeError: exit
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Interrupted: 1 errors during collection !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

'''

Nothing special on test. Just copy/paste examples here and got the error.

@megetron are you running your mamba tests with pytest? You should run your tests with the mamba CLI tool. Also, try to name your mamba tests *_spec.py. Files with patterns test_*.py or *_test.py are picked up by unittest or pytest frameworks.

See the mamba docs for more info: https://mamba-bdd.readthedocs.io/en/latest/getting-started.html#your-first-example
