pMock

pMock is a Python module for testing Python code using mock objects.

...
import pmock
...
class InstrumentTest(unittest.TestCase):
    def test_low_quality_analysis(self):
        analyser_mock = pmock.Mock()
        analyser_mock.expects().analyse(pmock.eq("123")).will(pmock.return_value("30"))
        instrument = Instrument(analyser_mock)
        instrument.insert("sample#123")
        self.assert_(instrument.is_low_quality_indicator_on())
        analyser_mock.verify()
...

Inspired by the Java jMock library, pMock makes the writing of unit tests using mock object techniques easier.

The typical sequence of steps in a test involving pMock mock objects are:

Mock objects are created with expectations and simple behaviours
Code under test is called with the mock objects
Code state is asserted as in normal unit tests
The mock objects' expectations are verified (basically another assertion)

See the overview for an introduction on how to use pMock in your unit tests.

Requirements

pMock is currently written for versions of Python >= 2.3
pMock is licensed under the same terms as Python
