I think you can just pass the np_array and assert_equal arguments, as this will mask wrong arguments

[dxe4]

@jorisvandenbossche ok will do, i thought this would be better because when 1 function changes then the other will have to be updated.

[jorisvandenbossche]

@papaloizouc Are you interested in trying to add the other assert_ functions to the TestCase?

[dxe4]

@jorisvandenbossche sure will do

[jorisvandenbossche]

I think we should try to do the adding of the methods a bit more automatically (so also the docstring are kept as the original).

Eg something like setattr(TestCase, 'assert_frame_equal', staticmethod(assert_frame_equal)) adds the method to the class keeping the docstring and signature

@jreback

[jreback]

sure easy enough to inspect the module namespace and auto add the methods to TestCase via a generated wrapper

[dxe4]

does this make sense?

[jreback]

you don't even need to do this in a function, just put it at the end of the module and directly update TestCase. (pls put a comment before though explaining what this is doing).
