assert_almost_equal(actual, desired[, …])

Raises an AssertionError if two items are not equal up to desired precision.

assert_array_almost_equal(x, y[, decimal, …])

Raises an AssertionError if two objects are not equal up to desired precision.

assert_allclose(actual, desired[, rtol, …])

Raises an AssertionError if two objects are not equal up to desired tolerance.

assert_array_almost_equal_nulp(x, y[, nulp])

Compare two arrays relatively to their spacing.

assert_array_max_ulp(a, b[, maxulp, dtype])

Check that all items of arrays differ in at most N Units in the Last Place.

assert_array_equal(x, y[, err_msg, verbose])

Raises an AssertionError if two array_like objects are not equal.

assert_array_less(x, y[, err_msg, verbose])

Raises an AssertionError if two array_like objects are not ordered by less than.

assert_equal(actual, desired[, err_msg, verbose])

Raises an AssertionError if two objects are not equal.

assert_raises(exception_class, callable, …)

Fail unless an exception of class exception_class is thrown by callable when invoked with arguments args and keyword arguments kwargs.

assert_raises_regex(exception_class, …)

Fail unless an exception of class exception_class and with message that matches expected_regexp is thrown by callable when invoked with arguments args and keyword arguments kwargs.

assert_warns(warning_class, \*args, \*\*kwargs)

Fail unless the given callable throws the specified warning.

assert_string_equal(actual, desired)

Test if two strings are equal.

dec.deprecated([conditional])

dec.knownfailureif(fail_condition[, msg])

Make function raise KnownFailureException exception if given condition is true.

dec.setastest([tf])

Signals to nose that this function is or is not a test.

dec.skipif(skip_condition[, msg])

Make function raise SkipTest exception if a given condition is true.

dec.slow(t)
