NAME

Test::Unit - Procedural style unit testing interface

SYNOPSIS

use Test::Unit;

# your code to be tested goes here

sub foo { return 23 };
sub bar { return 42 };

# define tests

sub test_foo { assert(foo() == 23); }	
sub test_bar { assert(bar() == 42); }

# set_up and tear_down are used to
# prepare and release resources need for testing

sub set_up    { print "hello world\n"; }
sub tear_down { print "leaving world again\n"; }

# run your test

create_suite();
run_suite();

DESCRIPTION

    Test::Unit is the procedural style interface to a sophisticated
    unit testing framework for Perl that is derived from the JUnit
    testing framework for Java by Kent Beck and Erich Gamma. While
    this framework is originally intended to support unit testing
    in an object-oriented development paradigm (with support for
    inheritance of tests etc.), Test::Unit is intended to  provide
    a simpler interface to the framework that is more suitable for
    use in a scripting style environment. Therefore, Test::Unit
    does not provide much support for an object-oriented approach
    to unit testing - if you want that, please have a look at
    Test::Unit::TestCase.

    You test a given unit (a script, a module, whatever) by using
    Test::Unit, which exports the following routines into your
    namespace:

    assert()       - used to assert that a boolean condition is true
    create_suite() - used to create a test suite consisting of all
                     methods with a name prefix of 'test'
    run_suite()    - runs the test suite (text output)
    add_suite()    - used to add test suites to each other
		     
    For convenience, create_suite() will automatically build a test
    suite for a given package. This will build a test case for each
    subroutine in the package given that has a name starting with
    "test" and pack them all together into one TestSuite object for
    easy testing. If you dont give a package name to create_suite(),
    the current package is taken as default.

    Test output is one status line (a "." for every successful test
    run, or an "F" for any failed test run, to indicate progress),
    one result line ("OK" or "!!!FAILURES!!!"), and possibly many
    lines reporting detailed error messages for any failed tests.

    Please remember, Test::Unit is intended to be a simple and
    convenient interface. If you need more functionality, take the
    object-oriented approach outlined in Test::Unit::TestCase.
