Apache::TestRunPHP - configure and run a PHP-based test suite
use Apache::TestRunPHP; Apache::TestRunPHP->new->run(@ARGV);
Apache::TestRunPHPpackage controls the configuration and running of the test suite for PHP-based tests. It's a subclass of
Apache::TestRunand similar in function to
Refer to the
Apache::TestRunmanpage for information on the available API.
TestRunPHPworks almost identially to
TestRunPerl, but in case you are new to
Apache-Testhere is a quick getting started guide. be sure to see the links at the end of this document for places to find additional details.
Apache-Testis a Perl-based testing framework we start from a
Makefile.PL, which should have the following lines (in addition to the standard
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
Apache::Test-specific arguments and passes them along. for example, to point to a specific
httpdinstallation you would invoke
$ perl Makefile.PL -httpd /my/local/apache/bin/httpd
/my/local/apache/bin/httpdwill 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
httpdbinary statically or through an active
LoadModulestatement within the configuration located in
/my/local/apache/conf/httpd.conf. Other required modules are the (very common) mod_alias and mod_env.
now, like with
Apache::TestRunPerl, you can place client-side Perl test scripts under
t/, such as
Apache-Testwill run these scripts when you call
make test. however, what makes
Apache::TestRunPHPunique is some added magic specifically tailored to a PHP environment. here are the mechanics.
Apache::TestRunPHPwill look for PHP test scripts in that match the following pattern
barcan be anything you like, and
t/response/Test*is case sensitive. when this format is adhered to,
Apache::TestRunPHPwill create an associated Perl test script called
t/foo/bar.t, which will be executed when you call
make test. all
bar.tdoes is issue a simple GET to
bar.php, leaving the actual testing to
bar.php. in essence, you can forget that
bar.phplook 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
bar.phpit feeds the results directly to
Test::Harness, a module that comes with every Perl installation, and
Test::Harnessexpects what it receives to be formated in a very specific way. by itself, all of this is pretty useless, so
Apache::Testprovides PHP testers with something much better. here is a much better example:
<?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.phpis automatically generated by
Apache::TestConfigPHPand configurations tweaked in such a a way that your PHP scripts can find it without issue. the functions provided by
test-more.phpare 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.
at this point, we have enough in place to run some tests from PHP-land - a
Makefile.PLto configure Apache for us, and a PHP script in
t/response/TestFoo/bar.phpto send some results out to the testing engine. issuing
make testwould 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):
t/php/bar....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/TestFoo/bar.php at line 13) ok 3 - bar is bar not ok 4 - baz is baz # Failed test (/src/devel/perl-php-test/t/response/TestFoo/bar.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/bar.t 6 3 50.00% 2 4 7 Failed 1/1 test scripts, 0.00% okay. 1/6 subtests failed, 83.33% okay.
note that the actual test file that was run was
t/php/bar.t. this file is autogenerated based on the
t/response/TestFoo/bar.phppattern of your PHP script.
t/php/bar.thappens to be written in Perl, but you really don't need to worry about it too much.
as an interesting aside, if you are using perl-5.8.3 or later you can actually create your own
t/foo.phpclient-side scripts and they will be run via php (using our
php.ini). but more on that later...
the best source of information about using Apache-Test with PHP (at this time) is probably the talk given at ApacheCon 2004 (http://xrl.us/phpperl), as well as the code from the talk (http://xrl.us/phpperlcode). there is also the online tutorial http://perl.apache.org/docs/general/testing/testing.html which has all of the mod_perl-specific syntax and features have been ported to PHP with this class.
Apache-Testis a community effort, maintained by a group of dedicated volunteers.
