This is documentation for an old release of NumPy (version 1.8.0). Read this page in the documentation of the latest stable release (version > 1.17).
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[, ...]) | Raise an assertion if two items are not equal up to desired precision. |
assert_approx_equal(actual, desired[, ...]) | Raise an assertion if two items are not equal up to significant digits. |
assert_array_almost_equal(x, y[, decimal, ...]) | Raise an assertion if two objects are not equal up to desired precision. |
assert_allclose(actual, desired[, rtol, ...]) | Raise an assertion 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]) | Raise an assertion if two array_like objects are not equal. |
assert_array_less(x, y[, err_msg, verbose]) | Raise an assertion if two array_like objects are not ordered by less than. |
assert_equal(actual, desired[, err_msg, verbose]) | Raise an assertion 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_warns(warning_class, func, *args, **kw) | 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 KnownFailureTest 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 | Nose test runner. |
run_module_suite([file_to_run]) | |
rundocs([filename, raise_on_error]) | Run doctests found in the given file. |
