Class: TestCase Twisted-0.17.4/pyunit/unittest.py

A class whose instances are single test cases.

By default, the test code itself should be placed in a method named runTest.

If the fixture may be used for many test cases, create as many test methods as are needed. When instantiating such a TestCase subclass, specify in the constructor arguments the name of the test method that the instance is to execute.

Test authors should subclass TestCase for their own tests. Construction and deconstruction of the test's environment (fixture) can be implemented by overriding the setUp and tearDown methods respectively.

If it is necessary to override the __init__ method, the base class __init__ method must always be called. It is important that subclasses should not change the signature of their __init__ method, since instances of the classes are instantiated automatically by parts of the framework in order to be run.

  __call__ 
__call__ ( self,  result=None )

  __exc_info 
__exc_info ( self )

Return a version of sys.exc_info() with the traceback frame minimised; usually the top level of the traceback frame is not needed.

  __init__ 
__init__ ( self,  methodName='runTest' )

Create an instance of the class that will use the named test method when executed. Raises a ValueError if the instance does not have a method with the specified name.

Exceptions   
ValueError, "no such test method in %s: %s" %( self.__class__, methodName )
  __repr__ 
__repr__ ( self )

  __str__ 
__str__ ( self )

  countTestCases 
countTestCases ( self )

  debug 
debug ( self )

Run the test without collecting errors in a TestResult

  defaultTestResult 
defaultTestResult ( self )

  fail 
fail ( self,  msg=None )

Fail immediately, with the given message.

Exceptions   
self.failureException, msg
  failIf 
failIf (
        self,
        expr,
        msg=None,
        )

Fail the test if the expression is true.

Exceptions   
self.failureException, msg
  failIfEqual 
failIfEqual (
        self,
        first,
        second,
        msg=None,
        )

Fail if the two objects are equal as determined by the == operator.

Exceptions   
self.failureException, (msg or '%s == %s' %(repr( first ), repr( second ) ) )
  failUnless 
failUnless (
        self,
        expr,
        msg=None,
        )

Fail the test unless the expression is true.

Exceptions   
self.failureException, msg
  failUnlessEqual 
failUnlessEqual (
        self,
        first,
        second,
        msg=None,
        )

Fail if the two objects are unequal as determined by the != operator.

Exceptions   
self.failureException, (msg or '%s != %s' %(repr( first ), repr( second ) ) )
  failUnlessRaises 
failUnlessRaises (
        self,
        excClass,
        callableObj,
        *args,
        *kwargs,
        )

Fail unless an exception of class excClass is thrown by callableObj when invoked with arguments args and keyword arguments kwargs. If a different type of exception is thrown, it will not be caught, and the test case will be deemed to have suffered an error, exactly as for an unexpected exception.

Exceptions   
self.failureException, excName
  id 
id ( self )

  run 
run ( self,  result=None )

  setUp 
setUp ( self )

Hook method for setting up the test fixture before exercising it.

  shortDescription 
shortDescription ( self )

Returns a one-line description of the test, or None if no description has been provided.

The default implementation of this method returns the first line of the specified test method's docstring.

  tearDown 
tearDown ( self )

Hook method for deconstructing the test fixture after testing it.
