BUG: assert_index_equal(CategoricalIndex, CategoricalIndex, check_categorical=True, exact=False) raises TypeError instead of AssertionError (original) (raw)

Pandas version checks

• I have checked that this issue has not already been reported.
• I have confirmed this bug exists on the latest version of pandas.
• I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

In [1]: import pandas as pd

In [2]: p_left = pd.Index([1, 2, 3], name="a", dtype="category")

In [3]: p_right = pd.Index([1, 2, 6], name="a", dtype="category")

In [4]: pd.testing.assert_index_equal(p_left, p_right, check_categorical=True, exact=False)

TypeError Traceback (most recent call last) Cell In[10], line 1 ----> 1 pd.testing.assert_index_equal(p_left, p_right, check_categorical=True, exact=False)

Issue Description

pandas asserters should always raise an AssertionError.

Expected Behavior

I would expect this to raise an AssertionError.
