numpy.testing.assert_string_equal(actual, desired)[source]¶

Test if two strings are equal.

If the given strings are equal, assert_string_equal does nothing. If they are not equal, an AssertionError is raised, and the diff between the strings is shown.

Parameters

actualstr

The string to test for equality against the expected string.

desiredstr

The expected string.

Examples

>>> np.testing.assert_string_equal('abc', 'abc')
>>> np.testing.assert_string_equal('abc', 'abcd')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
...
AssertionError: Differences in strings:
- abc+ abcd?    +
