# 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_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.
