assert_almost_equal(actual, desired[, ...])	Raises an AssertionError if two items are not equal up to desired precision.
assert_approx_equal(actual, desired[, ...])	Raises an AssertionError if two items are not equal up to significant digits.
assert_array_almost_equal(x, y[, decimal, ...])	Raises an AssertionError if two objects are not equal up to desired precision.
assert_array_equal(x, y[, err_msg, verbose])	Raises an AssertionError if two array_like objects are not equal.
assert_array_lequal(x, y)
assert_array_less(x, y[, err_msg, verbose])	Raises an AssertionError if two array_like objects are not ordered by less than.

assert_datasets_almost_equal(x, y[, ...])	Parameters:
assert_datasets_equal(x, y[, ignore_a, ...])	Parameters:
assert_dict_keys_equal(x, y)
assert_objectarray_equal(x, y[, xorig, ...])	Wrapper around assert_array_equal to compare object arrays

make_decorator(func)	Wraps a test decorator so as to properly replicate metadata of the decorated function, including nose’s additional stuff (namely, setup and teardown).
nodebug([entries])	Decorator to temporarily turn off some debug targets
nottest(func)	Decorator to mark a function or method as not a test
ok_(expr[, msg])	Shorthand for assert.
