What is the difference between `assert_frame_equal` and `equals`

Question

I\'m curious to find the difference between assert_frame_equal and equal. Both are for checking the equality of two data. It applies for assert_s

Answer 1

assert_frame_equal throws an AssertionError when two DataFrames aren't equal.

pd.testing.assert_frame_equal(df1, df2)            # no result - pass

pd.testing.assert_frame_equal(df1, pd.DataFrame()) # throws error - fail
# AssertionError       

DataFrame.equals simply returns a boolean True/False.

df1.equals(df2)
# True

df1.equals(pd.DataFrame())
# False    

This is also the case for the other functions defined in pd.testing, which are used to develop unit tests for pandas code.
