Common test support for all numpy test scripts.

This single module should provide all the common functionality for numpy tests in a single location, so that test scriptsopen in new window can just import it and work right away. For background, see the Testing Guidelines

Asserts

method	description
assert_almost_equalopen in new window(actual, desired[, …])	Raises an AssertionError if two items are not equal up to desired precision.
assert_approx_equalopen in new window(actual, desired[, …])	Raises an AssertionError if two items are not equal up to significant digits.
assert_array_almost_equalopen in new window(x, y[, decimal, …])	Raises an AssertionError if two objects are not equal up to desired precision.
assert_allcloseopen in new window(actual, desired[, rtol, …])	Raises an AssertionError if two objects are not equal up to desired tolerance.
assert_array_almost_equal_nulpopen in new window(x, y[, nulp])	Compare two arrays relatively to their spacing.
assert_array_max_ulpopen in new window(a, b[, maxulp, dtype])	Check that all items of arrays differ in at most N Units in the Last Place.
assert_array_equalopen in new window(x, y[, err_msg, verbose])	Raises an AssertionError if two array_like objects are not equal.
assert_array_lessopen in new window(x, y[, err_msg, verbose])	Raises an AssertionError if two array_like objects are not ordered by less than.
assert_equalopen in new window(actual, desired[, err_msg, verbose])	Raises an AssertionError if two objects are not equal.
assert_raisesopen in new window(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_regexopen in new window(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_warnsopen in new window(warning_class, args, *kwargs)	Fail unless the given callable throws the specified warning.
assert_string_equalopen in new window(actual, desired)	Test if two strings are equal.

Decorators

method	description
decorators.deprecatedopen in new window([conditional])	Filter deprecation warnings while running the test suite.
decorators.knownfailureifopen in new window(fail_condition[, msg])	Make function raise KnownFailureException exception if given condition is true.
decorators.setastestopen in new window([tf])	Signals to nose that this function is or is not a test.
decorators.skipifopen in new window(skip_condition[, msg])	Make function raise SkipTest exception if a given condition is true.
decorators.slowopen in new window(t)	Label a test as ‘slow’.
decorate_methodsopen in new window(cls, decorator[, testmatch])	Apply a decorator to all methods in a class matching a regular expression.

Test Running

method	description
Testeropen in new window	alias of numpy.testing._private.nosetester.NoseTester
run_module_suiteopen in new window([file_to_run, argv])	Run a test module.
rundocsopen in new window([filename, raise_on_error])	Run doctests found in the given file.
suppress_warningsopen in new window([forwarding_rule])	Context manager and decorator doing much the same as warnings.catch_warnings.
