Add a tests for our tests helpers

[TomAugspurger]

Dask uses a couple assert_eq helpers for easily testing the equality of the result of a computation (a dask.array or dask.dataframe say) to the expected value (np.array, pd.DataFrame). It'd be nice to have some tests for these helpers to ensure they're functioning properly

• array:

  dask/dask/array/utils.py

  Line 62 in a1a75a7

  def assert_eq(a, b, check_shape=True, **kwargs):

• dataframe:

  dask/dask/dataframe/utils.py

  Line 553 in a1a75a7

  def assert_eq(a, b, check_names=True, check_dtypes=True,

See https://github.com/dask/dask/pull/2681/files#diff-20d741e3b309789af8da0fbc2663f964 for an example of the kinds of tests we would be good to have.

@TomAugspurger Does this issue still require a PR, if so Im happy to work on it ?

[TomAugspurger]

I suspect it's still open. At a glance, I didn't see any tests named "test_assert_eq".

Ok will have a look and submit a PR

hey there, i'd like to help with this but im unsure how much work is already done since the time the issue was opened. I could use some help with what stuff I could contribute, I think the dask.arrays.test.test_testing module could still be expanded as mentioned in #2681?
