Test::Unit::Assertion(User Contributed Perl DocumentatTest::Unit::Assertion(3)NAMETest::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.
