Your sentence has just enough typos to lead me to doubt I understand you. What do you mean, add a test "to pandas Int the first case..." ? What's a NaT value? > def > test_day_not_in_month_coerce_true > () works If it works, why is it relevant to your question? > I am trying to duplicate them with coerce= > False which > will give a ValueError but I cant get the tests to work.

I don't see anything obviously wrong in your use of the assertRaises method, *assuming* that it is the assertRaises method from the standard library unittest module. If it is some custom method written by you, or part of pandas, then I have no idea if you are doing something wrong. But I expect that the real problem is that you are mistaken to believe that to_datetime('2015-02-29', coerce=False) raises ValueError. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
