Apache::TestRunPHP - configure and run a PHP-based test suite
use Apache::TestRunPHP; Apache::TestRunPHP->new->run(@ARGV);
The Apache::TestRunPHP package controls the configuration and running of the test suite for PHP-based tests. It's a subclass of Apache::TestRun and similar in function to Apache::TestRunPerl.

Apache::TestRun
Apache::TestRunPerl
Refer to the Apache::TestRun manpage for information on the available API.
TestRunPHP works almost identially to TestRunPerl, but in case you are new to Apache-Test here is a quick getting started guide. be sure to see the links at the end of this document for places to find additional details.
TestRunPHP
TestRunPerl
Apache-Test
because Apache-Test is a Perl-based testing framework we start from a Makefile.PL, which should have the following lines (in addition to the standard Makefile.PL parts):
Makefile.PL
use Apache::TestMM qw(test clean); use Apache::TestRunPHP (); Apache::TestMM::filter_args(); Apache::TestRunPHP->generate_script();
generate_script() will create a script named t/TEST, the gateway to the Perl testing harness and what is invoked when you call make test. filter_args() accepts some Apache::Test-specific arguments and passes them along. for example, to point to a specific httpd installation you would invoke Makefile.PL as follows
generate_script()
t/TEST
make test
filter_args()
Apache::Test
httpd
$ perl Makefile.PL -httpd /my/local/apache/bin/httpd
and /my/local/apache/bin/httpd will be propagated throughout the rest of the process. note that PHP needs to be active within Apache prior to configuring the test framework as shown above, either by virtue of PHP being compiled into the httpd binary statically or through an active LoadModule statement within the configuration located in /my/local/apache/conf/httpd.conf. Other required modules are the (very common) mod_alias and mod_env.
/my/local/apache/bin/httpd
LoadModule
/my/local/apache/conf/httpd.conf
now, like with Apache::TestRun and Apache::TestRunPerl, you can place client-side Perl test scripts under t/, such as t/01basic.t, and Apache-Test will run these scripts when you call make test. however, what makes Apache::TestRunPHP unique is some added magic specifically tailored to a PHP environment. here are the mechanics.
t/
t/01basic.t
Apache::TestRunPHP will look for PHP test scripts in that match the following pattern
t/response/TestFoo/bar.php
where Foo and bar can be anything you like, and t/response/Test* is case sensitive. when this format is adhered to, Apache::TestRunPHP will create an associated Perl test script called t/foo/bar.t, which will be executed when you call make test. all bar.t does is issue a simple GET to bar.php, leaving the actual testing to bar.php. in essence, you can forget that bar.t even exists.
Foo
bar
t/response/Test*
t/foo/bar.t
bar.t
bar.php
what does bar.php look like? here is an example:
<?php print "1..1\n"; print "ok 1\n" ?>
if it looks odd, that's ok because it is. I could explain to you exactly what this means, but it isn't important to understand the gory details. instead, it is sufficient to understand that when Apache::Test calls bar.php it feeds the results directly to Test::Harness, a module that comes with every Perl installation, and Test::Harness expects what it receives to be formated in a very specific way. by itself, all of this is pretty useless, so Apache::Test provides PHP testers with something much better. here is a much better example:
Test::Harness
<?php # import the Test::More emulation layer # see # http://search.cpan.org/dist/Test-Simple/lib/Test/More.pm # for Perl's documentation - these functions should behave # in the same way require 'test-more.php'; # plan() the number of tests plan(6); # call ok() for each test you plan ok ('foo' == 'foo', 'foo is equal to foo'); ok ('foo' != 'foo', 'foo is not equal to foo'); # ok() can be other things as well is ('bar', 'bar', 'bar is bar'); is ('baz', 'bar', 'baz is baz'); isnt ('bar', 'beer', 'bar is not beer'); like ('bar', '/ar$/', 'bar matches ar$'); diag("printing some debugging information"); # whoops! one too many tests. I wonder what will happen... is ('biff', 'biff', 'baz is a baz'); ?>
the include library test-more.php is automatically generated by Apache::TestConfigPHP and configurations tweaked in such a a way that your PHP scripts can find it without issue. the functions provided by test-more.php are equivalent in name and function to those in Test::More, a standard Perl testing library, so you can see that manpage for details on the syntax and functionality of each.
test-more.php
Apache::TestConfigPHP
Test::More
at this point, we have enough in place to run some tests from PHP-land - a Makefile.PL to configure Apache for us, and a PHP script in t/response/TestFoo/bar.php to send some results out to the testing engine. issuing make test would start Apache, issue the request to bar.php, generate a report, and shut down Apache. the report would look like something like this after running the tests in verbose mode (eg make test TEST_VERBOSE=1):
make test TEST_VERBOSE=1
t/php/foo....1..6 ok 1 - foo is equal to foo not ok 2 - foo is not equal to foo # Failed test (/src/devel/perl-php-test/t/response/TestPHP/foo.php at line 13) ok 3 - bar is bar not ok 4 - baz is baz # Failed test (/src/devel/perl-php-test/t/response/TestPHP/foo.php at line 17) # got: 'baz' # expected: 'bar' ok 5 - bar is not beer ok 6 - bar matches ar$ # printing some debugging information ok 7 - baz is a baz FAILED tests 2, 4, 7 Failed 3/6 tests, 50.00% okay Failed Test Stat Wstat Total Fail Failed List of Failed ------------------------------------------------------------------------------- t/php/foo.t 6 3 50.00% 2 4 7 Failed 1/1 test scripts, 0.00% okay. 1/6 subtests failed, 83.33% okay.
The Apache-Test tutorial: http://perl.apache.org/docs/general/testing/testing.html as all of the mod_perl-specific syntax and features have been ported to PHP with this class.
Apache::Test is a community effort, maintained by a group of dedicated volunteers.
