Dave's Unit Test 0.8.2 (Default branch)
Dave's Unit Test (DUT) is a simple infrastructure for doing unit testing in C and C++. It can test boolean assertions, and test for the existence of expected C++ exceptions or POSIX signals. It also traps unexpected exceptions or signals. License: GNU General Public License v2 Changes:
This release adds warning-only versions of all test macros, has several minor dut.make bugfixes, and introduces some macros for the new test language based on the type to be tested rather than user supplied cache variables.Image

Test::Unit::Assertion::Regexp(3pm)			User Contributed Perl Documentation			Test::Unit::Assertion::Regexp(3pm)

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...
