Test::Extreme 0.12

Test::Extreme is a perlish unit testing framework.

SYNOPSIS

# In ModuleOne.pm combine unit tests with code

package ModuleOne;
use Test::Extreme;
sub foo { return 23 };
sub test_foo { assert_equals foo, 23 }

# at the end of the module

run_tests 'ModuleOne' if $0 =~ /ModuleOne.pm$/;

# To run the tests in this module on the command line type

perl ModuleOne.pm

# If you have tests in several modules (say in ModuleOne.pm,
# ModuleTwo.pm and ModuleThree.pm, create test.pl containing
# precisely the following:

use ModuleOne;
use ModuleTwo;
use ModuleThree;

run_tests 'ModuleOne', 'ModuleTwo', 'ModuleThree',

# Then run these tests on the command line with

perl test.pl

# If you prefer to get Perl's classic "ok/not ok" output use
# replace run_tests with run_tests_as_script in all of the
# above

# Also take a look at Test/Extreme.pm which includes its own
# unit tests for how to instrument a module with unit tests

Test::Extreme is a perlish port of the xUnit testing
framework. It is in the spirit of JUnit, the unit testing
framework for Java, by Kent Beck and Erich Gamma. Instead of
porting the implementation of JUnit we have ported its spirit
to Perl.

The target market for this module is perlish people
everywhere who value laziness above all else.

Test::Extreme is especially written so that it can be easily
and concisely used from Perl programs without turning them
into Java and without inducing object-oriented nightmares in
innocent Perl programmers. It has a shallow learning curve.
The goal is to adopt the unit testing idea minus the OO
cruft, and to make the world a better place by promoting the
virtues of laziness, impatience and hubris.

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

assert $x - $x is true
assert_true $x - $x is true
assert_false $x - $x is not true
assert_passed - the last eval did not die ($@ eq "")
assert_failed - the last eval caused a die ($@ ne "")
assert_some $x - $x is true
assert_none - $x is false
assert_equals $x, $y - recursively tests arrayrefs, hashrefs
and strings to ensure they have the same
contents
assert_contains $string, $list
- $list contains $string assert_subset
$element_list, $list - $element_list is
a subset of $list (both are arrayrefs)
assert_is_array $x - $x is an arrayref
assert_is_hash $x - $x is a hashref
assert_is_string $x - $x is a scalar
assert_size N, $list - the arrayref contains N elements
assert_keys ['k1', 'k2'], $hash
- $hash contains k1, k2 as keys

run_tests_as_script - run all tests in package main and emit
Perl's classic "ok/not ok" style output

run_tests_as_script NS1, NS2, ...
- run all tests in package main, NS1,
NS2, and so on and emit Perl's classic
"ok/not ok" style output

run_tests - run all tests in package main

run_tests NS1, NS2, ...
- run all tests in package main, NS1,
NS2, and so on

For an example on how to use these assert take a look at Test/Extreme.pm which includes it own unit tests and illustrates different ways of using these asserts.

The function run_tests finds all functions that start with the word test (preceded by zero or more underscores) and runs them one at a time. It looks in the 'main' namespace by default and also looks in any namespaces passed to it as arguments.

Running the tests generates a status line (a "." for every successful test run, or an "F" for any failed test run), a summary result line ("OK" or "FAILURES!!!") and zero or more lines containing detailed error messages for any failed
tests.

To get Perl's classic "ok/not ok" style output (which is useful for writing test scripts) use run_tests_as_script instead of run_tests.
