Test Support (numpy.testing
)
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 scripts can just import it and
work right away.
Asserts
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_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. |
Decorators
decorators.deprecated ([conditional]) |
Filter deprecation warnings while running the test suite. |
decorators.knownfailureif (fail_condition[, msg]) |
Make function raise KnownFailureException exception if given condition is true. |
decorators.setastest ([tf]) |
Signals to nose that this function is or is not a test. |
decorators.skipif (skip_condition[, msg]) |
Make function raise SkipTest exception if a given condition is true. |
decorators.slow (t) |
Label a test as ‘slow’. |
decorate_methods (cls, decorator[, testmatch]) |
Apply a decorator to all methods in a class matching a regular expression. |
Test Running
Tester |
alias of numpy.testing.nose_tools.nosetester.NoseTester |
run_module_suite ([file_to_run, argv]) |
Run a test module. |
rundocs ([filename, raise_on_error]) |
Run doctests found in the given file. |
suppress_warnings ([forwarding_rule]) |
Context manager and decorator doing much the same as warnings.catch_warnings . |
