I{Private} test utilities for use throughout Twisted's test suite.  Unlike
C{proto_helpers}, this is no exception to the
don't-use-it-outside-Twisted-we-won't-maintain-compatibility rule!

@note: Maintainers be aware: things in this module should be gradually promoted
    to more full-featured test helpers and exposed as public API as your
    maintenance time permits.  In order to be public API though, they need
    their own test cases.

    A mixin which defines a method for making assertions about the correctness
    of an implementation of C{==} and C{!=}.

Use this to unit test objects which follow the common convention for C{==}
    and C{!=}:

- The object compares equal to itself
        - The object cooperates with unrecognized types to allow them to
          implement the comparison
        - The object implements not-equal as the opposite of equal

        Assert that C{firstValueOne} is equal to C{secondValueOne} but not
        equal to C{valueOne} and that it defines equality cooperatively with
        other types it doesn't know about.

@param firstValueOne: An object which is expected to compare as equal
            to C{secondValueOne} and not equal to C{valueTwo}.

@param secondValueOne: A different object than C{firstValueOne} but
            which is expected to compare equal to that object.

@param valueTwo: An object which is expected to compare as not equal to
            C{firstValueOne}.
