[docs]def assertDeepAlmostEqual(expected, actual, *args, **kwargs):
"""
Assert that two complex structures have almost equal contents.
Compares lists, dicts and tuples recursively. Checks numeric values
using test_case's :py:meth:`unittest.TestCase.assertAlmostEqual` and
checks all other values with :py:meth:`unittest.TestCase.assertEqual`.
Accepts additional positional and keyword arguments and pass those
intact to assertAlmostEqual() (that's how you specify comparison
precision).
Parameters
----------
decimal: int
The desired positional precision.
See numpy.testing.assert_array_almost_equal for keyword arguments
