@jreback Got it. Apologies for that! This was my first contribution - the last PR got a bit messy. Will be careful next time. Thanks! |
|
no prob. It just keeps a better chain to have a single PR. |
Coverage gives wrong percentage if imports are missing
|
@jreback the new method that I added has some googleapiclient imports which cause the test to not completely capture the lines of codes. Can someone please have a look and close or suggest further actions. Thanks, |

you need to follow the existing pattern, why is this a staticmethod? that's non-pythonic.
nested try/except is a no-no
just call your routine, if the default oauth imports raise you don't care, the user will get an import error.
only the addl imports (for getting default credientials) need to be caught (and return None).
you can

@jreback I will incorporate all the changes you suggested. Thank you for your time! p.s. things like nested try/catch; staticmethod; etc. I implemented these to trick codecov and nosetests to cover/pass test for the new method. I will revert these changes. |

@jreback incorporated the suggested changes. Thanks! :) |

Hi @jreback I was wondering - did you have a look at my last changes? Is the pull request eligible to be merged? Thanks! :) |

needs tests |
|
@jreback I have written this test "test_get_application_default_credentials_should_not_throw_error" which should call (cover) the new method I've added. The "test environment" is probably skipping (TestGBQConnectorIntegration.setUp) this test because "project_id" is not set. I am guessing - even if I add more tests they will be skipped. As you can see from the coverage report - not even the first line of the method is covered - If I am not understanding this correctly - could you please guide me how to solve this. Thank you for your time! |

so you need to do skipping based on resource availablity, see the other tests.

Hi @jreback, do you think the pull request is fine now. The second test (test_get_application_default_credentials_returns_credentials) will only be executed (not skipped) if a google account is authenticated (for gcloud) on the environment. |

Move this inside of try so tests pass with oauth2client==1.2
