NAME

6       Test::Unit::Assertion - The abstract base class for assertions
7

NAME

9       Any assertion class that expects to plug into Test::Unit::Assert needs
10       to implement this interface.
11
12   Required methods
13       new Creates a new assertion object. Takes whatever arguments you
14           desire.  Isn't strictly necessary for the framework to work with
15           this class but is generally considered a good idea.
16
17       do_assertion
18           This is the important one. If Test::Unit::Assert::assert is called
19           with an object as its first argument then it does:
20
21               $_[0]->do_assertion(@_[1 .. $#_]) ||
22                   $self->fail("Assertion failed");
23
24           This means that "do_assertion" should return true if the assertion
25           succeeds and false if it doesn't. Or, you can fail by throwing a
26           Test::Unit::Failure object, which will get caught further up the
27           stack and used to produce a sensible error report. Generally it's
28           good practice for do_assertion to die with a meaningful error on
29           assertion failure rather than just returning false.
