"""
Test the behavior of the test helper function.
The arguments `f`, `args`, `kwargs`, and `expected` are to be
passed directly to `~plasmapy.utils.run_test`. If the test is
expected to pass, then `whaterror` should be set to `None`. If the
test is expected to fail, then `whaterror` should be set to the
exception that should be raised during the test failure.
This function does not test that the exception messages are correct;
it only checks that the exception messages do not raise any
unexpected exceptions.
Parameters
----------
f : callable
The function or method to be tested.
args : tuple
The positional arguments to be sent to f.
kwargs : dict
The keyword arguments to be sent to f.
expected : object
The expected result from the test, which can be an `object`, an
exception, a warning, or a `tuple` containing the expected
result and the type of warning.
whaterror : exception or None
The type of exception that the test helper function is supposed
to raise, or `None` if the test helper function is not supposed
to raise an exception.
