Test::Unit::Assertion - phpMan

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 failure rather than just returning false.
