NAME
       Test::Unit::Assertion - The abstract base class for assertions

NAME
       Any assertion class that expects to plug into Test::Unit::Assert needs to implement this
       interface.

       Required methods


       new Creates a new assertion object. Takes whatever arguments you desire.  Isn't strictly
           necessary for the framework to work with this class but is generally considered a good
           idea.

       do_assertion
           This is the important one. If Test::Unit::Assert::assert is called with an object as
           its first argument then it does:

               $_[0]->do_assertion(@_[1 .. $#_]) ||
                   $self->fail("Assertion failed");

           This means that "do_assertion" should return true if the assertion succeeds and false
           if it doesn't. Or, you can fail by throwing a Test::Unit::Failure object, which will
           get caught further up the stack and used to produce a sensible error report. Generally
           it's good practice for do_assertion to die with a meaningful error on assertion fail-
           ure rather than just returning false.
