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.
