NAME

       Test::Harness::Assert - simple assert

SYNOPSIS

	 ### FOR INTERNAL USE ONLY ###

	 use Test::Harness::Assert;

	 assert( EXPR, $name );

DESCRIPTION

       A simple assert routine since we don't have Carp::Assert handy.

FUNCTIONS

       "assert()"

	 assert( EXPR, $name );

       If the expression is false the program aborts.

NAME

       Test::Unit::Assertion::Regexp - Assertion with regex matching

SYNOPSIS

	   require Test::Unit::Assertion::Regexp;

	   my $assert_re =
	     Test::Unit::Assertion::Regexp->new(qr/a_pattern/);

	   $assert_re->do_assertion('a_string');

       This is rather more detail than the average user will need.  Test::Unit::Assertion::Regexp objects are generated automagically by
       Test::Unit::Assert::assert when it is passed a regular expression as its first parameter.

	   sub test_foo {
	     ...
	     $self->assert(qr/some_pattern/, $result);
	   }

       If the assertion fails then the object throws an exception with details of the pattern and the string it failed to match against.

       Note that if you need to do a 'string does not match this pattern' type of assertion then you can do:

	  $self->assert(qr/(?!some_pattern)/, $some_string)

       ie. Make use of the negative lookahead assertion.

IMPLEMENTS

       Test::Unit::Assertion::Regexp implements the Test::Unit::Assertion interface, which means it can be plugged into the Test::Unit::TestCase
       and friends' "assert" method with no ill effects.

DESCRIPTION

       The class is used by the framework to provide sensible 'automatic' reports when a match fails. The old:

	   $self->assert(scalar($foo =~ /pattern/), "$foo didn't match /.../");

       seems rather clumsy compared to this. If the regexp assertion fails, then the user is given a sensible error message, with the pattern and
       the string that failed to match it...
