Here we have not provided a :meth:`~TestCase.runTest` method, but have instead
provided two different test methods. Class instances will now each run one of
-the :meth:`test\*` methods, with ``self.widget`` created and destroyed
+the :meth:`test_\*` methods, with ``self.widget`` created and destroyed
separately for each instance. When creating an instance we must specify the
test method it is to run. We do this by passing the method name in the
constructor::
- defaultSizeTestCase = WidgetTestCase('testDefaultSize')
- resizeTestCase = WidgetTestCase('testResize')
+ defaultSizeTestCase = WidgetTestCase('test_default_size')
+ resizeTestCase = WidgetTestCase('test_resize')
Test case instances are grouped together according to the features they test.
:mod:`unittest` provides a mechanism for this: the :dfn:`test suite`,
represented by :mod:`unittest`'s :class:`TestSuite` class::
widgetTestSuite = unittest.TestSuite()
- widgetTestSuite.addTest(WidgetTestCase('testDefaultSize'))
- widgetTestSuite.addTest(WidgetTestCase('testResize'))
+ widgetTestSuite.addTest(WidgetTestCase('test_default_size'))
+ widgetTestSuite.addTest(WidgetTestCase('test_resize'))
For the ease of running tests, as we will see later, it is a good idea to
provide in each test module a callable object that returns a pre-built test
def suite():
suite = unittest.TestSuite()
- suite.addTest(WidgetTestCase('testDefaultSize'))
- suite.addTest(WidgetTestCase('testResize'))
+ suite.addTest(WidgetTestCase('test_default_size'))
+ suite.addTest(WidgetTestCase('test_resize'))
return suite
or even::
def suite():
- tests = ['testDefaultSize', 'testResize']
+ tests = ['test_default_size', 'test_resize']
return unittest.TestSuite(map(WidgetTestCase, tests))
suite = unittest.TestLoader().loadTestsFromTestCase(WidgetTestCase)
-will create a test suite that will run ``WidgetTestCase.testDefaultSize()`` and
-``WidgetTestCase.testResize``. :class:`TestLoader` uses the ``'test'`` method
+will create a test suite that will run ``WidgetTestCase.test_default_size()`` and
+``WidgetTestCase.test_resize``. :class:`TestLoader` uses the ``'test'`` method
name prefix to identify test methods automatically.
Note that the order in which the various test cases will be run is
def suite():
suite = unittest.TestSuite()
- suite.addTest(WidgetTestCase('testDefaultSize'))
- suite.addTest(WidgetTestCase('testResize'))
+ suite.addTest(WidgetTestCase('test_default_size'))
+ suite.addTest(WidgetTestCase('test_resize'))
return suite
Here, we create two instances of :class:`WidgetTestCase`, each of which runs a
