Nose Testing - Tools
The nose.tools module provides a number of testing aids that you may find useful, including decorators for restricting test execution time and testing for exceptions, and all of the same assertX methods found in unittest.TestCase.
nose.tools.ok_(expr, msg = None) − Shorthand for assert.
nose.tools.eq_(a, b, msg = None) − Shorthand for ‘assert a == b, “%r != %r” % (a, b)
nose.tools.make_decorator(func) − Wraps a test decorator so as to properly replicate metadata of the decorated function, including nose’s additional stuff (namely, setup and teardown).
nose.tools.raises(*exceptions) − Test must raise one of expected exceptions to pass.
nose.tools.timed(limit) − Test must finish within specified time limit to pass
nose.tools.istest(func) − Decorator to mark a function or method as a test
nose.tools.nottest(func) − Decorator to mark a function or method as not a test
Parameterized Testing
Python's testing framework, unittest, doesn't have a simple way of running parametrized test cases. In other words, you can't easily pass arguments into a unittest.TestCase from outside.
However, pytest module ports test parametrization in several well-integrated ways −
pytest.fixture() allows you to define parametrization at the level of fixture functions.
@pytest.mark.parametrize allows to define parametrization at the function or class level. It provides multiple argument/fixture sets for a particular test function or class.
pytest_generate_tests enables implementing your own custom dynamic parametrization scheme or extensions.
A third party module 'nose-parameterized' allows Parameterized testing with any Python test framework. It can be downloaded from this link − https://github.com/wolever/nose-parameterized
