Test Cases¶
nose unittest.TestCase subclasses. It is not necessary to subclass these classes when writing tests; they are used internally by nose.loader.TestLoader to create test cases from test functions and methods in test classes.
- 
class nose.case.Test(test, config=None, resultProxy=None)¶
- The universal test case wrapper. - When a plugin sees a test, it will always see an instance of this class. To access the actual test case that will be run, access the test property of the nose.case.Test instance. - 
address()¶
- Return a round-trip name for this test, a name that can be fed back as input to loadTestByName and (assuming the same plugin configuration) result in the loading of this test. 
 - 
afterTest(result)¶
- Called after test is complete (after result.stopTest) 
 - 
beforeTest(result)¶
- Called before test is run (before result.startTest) 
 - 
context¶
- Get the context object of this test (if any). 
 - 
exc_info()¶
- Extract exception info. 
 - 
id()¶
- Get a short(er) description of the test 
 - 
run(result)¶
- Modified run for the test wrapper. - From here we don’t call result.startTest or stopTest or addSuccess. The wrapper calls addError/addFailure only if its own setup or teardown fails, or running the wrapped test fails (eg, if the wrapped “test” is not callable). - Two additional methods are called, beforeTest and afterTest. These give plugins a chance to modify the wrapped test before it is called and do cleanup after it is called. They are called unconditionally. 
 - 
runTest(result)¶
- Run the test. Plugins may alter the test by returning a value from prepareTestCase. The value must be callable and must accept one argument, the result instance. 
 
- 
- 
class nose.failure.Failure(exc_class, exc_val, tb=None, address=None)¶
- Unloadable or unexecutable test. - A Failure case is placed in a test suite to indicate the presence of a test that could not be loaded or executed. A common example is a test module that fails to import.
