## Class TestCase

Known Subclasses:
  `ParseTestCase`

    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.

Method Details

### __init__(self, methodName='runTest') (Constructor)
    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.

### assert_(self, expr, msg=None)
    Fail the test unless the expression is true.

### assertEqual(self, first, second, msg=None)
    Fail if the two objects are unequal as determined by the '!='
    operator.

### assertEquals(self, first, second, msg=None)
    Fail if the two objects are unequal as determined by the '!='
    operator.

### assertNotEqual(self, first, second, msg=None)
    Fail if the two objects are equal as determined by the '=='
    operator.

### assertNotEquals(self, first, second, msg=None)
    Fail if the two objects are equal as determined by the '=='
    operator.

### assertRaises(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.

### debug(self)
    Run the test without collecting errors in a TestResult

### fail(self, msg=None)
    Fail immediately, with the given message.

### failIf(self, expr, msg=None)
    Fail the test if the expression is true.

### failIfEqual(self, first, second, msg=None)
    Fail if the two objects are equal as determined by the '=='
    operator.

### failUnless(self, expr, msg=None)
    Fail the test unless the expression is true.

### failUnlessEqual(self, first, second, msg=None)
    Fail if the two objects are unequal as determined by the '!='
    operator.

### 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.

### setUp(self)
    Hook method for setting up the test fixture before exercising it.

### 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(self)
    Hook method for deconstructing the test fixture after testing it.
