6 Apache::TestRunPHP - configure and run a PHP-based test suite
7
9 use Apache::TestRunPHP;
10 Apache::TestRunPHP->new->run(@ARGV);
11
13 The "Apache::TestRunPHP" package controls the configuration and running
14 of the test suite for PHP-based tests. It's a subclass of
15 "Apache::TestRun" and similar in function to "Apache::TestRunPerl".
16 Refer to the "Apache::TestRun" manpage for information on the available
18 API.

21 "TestRunPHP" works almost identially to "TestRunPerl", but in case you
22 are new to "Apache-Test" here is a quick getting started guide. be
23 sure to see the links at the end of this document for places to find
24 additional details.
25 because "Apache-Test" is a Perl-based testing framework we start from a
27 "Makefile.PL", which should have the following lines (in addition to
28 the standard "Makefile.PL" parts):
29 use Apache::TestMM qw(test clean);
31 use Apache::TestRunPHP ();
32 Apache::TestMM::filter_args();
34 Apache::TestRunPHP->generate_script();
36 "generate_script()" will create a script named "t/TEST", the gateway to
38 the Perl testing harness and what is invoked when you call "make test".
39 "filter_args()" accepts some "Apache::Test"-specific arguments and
40 passes them along. for example, to point to a specific "httpd"
41 installation you would invoke "Makefile.PL" as follows
42 $ perl Makefile.PL -httpd /my/local/apache/bin/httpd
44 and "/my/local/apache/bin/httpd" will be propagated throughout the rest
46 of the process. note that PHP needs to be active within Apache prior
47 to configuring the test framework as shown above, either by virtue of
48 PHP being compiled into the "httpd" binary statically or through an
49 active "LoadModule" statement within the configuration located in
50 "/my/local/apache/conf/httpd.conf". Other required modules are the
51 (very common) mod_alias and mod_env.
52 now, like with "Apache::TestRun" and "Apache::TestRunPerl", you can
54 place client-side Perl test scripts under "t/", such as "t/01basic.t",
55 and "Apache-Test" will run these scripts when you call "make test".
56 however, what makes "Apache::TestRunPHP" unique is some added magic
57 specifically tailored to a PHP environment. here are the mechanics.
58 "Apache::TestRunPHP" will look for PHP test scripts in that match the
60 following pattern
61 t/response/TestFoo/bar.php
63 where "Foo" and "bar" can be anything you like, and "t/response/Test*"
65 is case sensitive. when this format is adhered to,
66 "Apache::TestRunPHP" will create an associated Perl test script called
67 "t/foo/bar.t", which will be executed when you call "make test". all
68 "bar.t" does is issue a simple GET to "bar.php", leaving the actual
69 testing to "bar.php". in essence, you can forget that "bar.t" even
70 exists.
71 what does "bar.php" look like? here is an example:
73 <?php
75 print "1..1\n";
76 print "ok 1\n"
77 ?>
78 if it looks odd, that's ok because it is. I could explain to you
80 exactly what this means, but it isn't important to understand the gory
81 details. instead, it is sufficient to understand that when
82 "Apache::Test" calls "bar.php" it feeds the results directly to
83 "Test::Harness", a module that comes with every Perl installation, and
84 "Test::Harness" expects what it receives to be formated in a very
85 specific way. by itself, all of this is pretty useless, so
86 "Apache::Test" provides PHP testers with something much better. here
87 is a much better example:
88 <?php
90 # import the Test::More emulation layer
91 # see
92 # http://search.cpan.org/dist/Test-Simple/lib/Test/More.pm
93 # for Perl's documentation - these functions should behave
94 # in the same way
95 require 'test-more.php';
96 # plan() the number of tests
98 plan(6);
99 # call ok() for each test you plan
101 ok ('foo' == 'foo', 'foo is equal to foo');
102 ok ('foo' != 'foo', 'foo is not equal to foo');
103 # ok() can be other things as well
105 is ('bar', 'bar', 'bar is bar');
106 is ('baz', 'bar', 'baz is baz');
107 isnt ('bar', 'beer', 'bar is not beer');
108 like ('bar', '/ar$/', 'bar matches ar$');
109 diag("printing some debugging information");
111 # whoops! one too many tests. I wonder what will happen...
113 is ('biff', 'biff', 'baz is a baz');
114 ?>
115 the include library "test-more.php" is automatically generated by
117 "Apache::TestConfigPHP" and configurations tweaked in such a a way that
118 your PHP scripts can find it without issue. the functions provided by
119 "test-more.php" are equivalent in name and function to those in
120 "Test::More", a standard Perl testing library, so you can see that
121 manpage for details on the syntax and functionality of each.
122 at this point, we have enough in place to run some tests from PHP-land
124 - a "Makefile.PL" to configure Apache for us, and a PHP script in
125 "t/response/TestFoo/bar.php" to send some results out to the testing
126 engine. issuing "make test" would start Apache, issue the request to
127 "bar.php", generate a report, and shut down Apache. the report would
128 look like something like this after running the tests in verbose mode
129 (eg "make test TEST_VERBOSE=1"):
130 t/php/bar....1..6
132 ok 1 - foo is equal to foo
133 not ok 2 - foo is not equal to foo
134 # Failed test (/src/devel/perl-php-test/t/response/TestFoo/bar.php at line 13)
135 ok 3 - bar is bar
136 not ok 4 - baz is baz
137 # Failed test (/src/devel/perl-php-test/t/response/TestFoo/bar.php at line 17)
138 # got: 'baz'
139 # expected: 'bar'
140 ok 5 - bar is not beer
141 ok 6 - bar matches ar$
142 # printing some debugging information
143 ok 7 - baz is a baz
144 FAILED tests 2, 4, 7
145 Failed 3/6 tests, 50.00% okay
146 Failed Test Stat Wstat Total Fail Failed List of Failed
147 -------------------------------------------------------------------------------

149 Failed 1/1 test scripts, 0.00% okay. 1/6 subtests failed, 83.33% okay.
150 note that the actual test file that was run was "t/php/bar.t". this
152 file is autogenerated based on the "t/response/TestFoo/bar.php" pattern
153 of your PHP script. "t/php/bar.t" happens to be written in Perl, but
154 you really don't need to worry about it too much.
155 as an interesting aside, if you are using perl-5.8.3 or later you can
157 actually create your own "t/foo.php" client-side scripts and they will
158 be run via php (using our "php.ini"). but more on that later...

161 the best source of information about using Apache-Test with PHP (at
162 this time) is probably the talk given at ApacheCon 2004
163 (<http://xrl.us/phpperl>), as well as the code from the talk
164 (<http://xrl.us/phpperlcode>). there is also the online tutorial
165 <http://perl.apache.org/docs/general/testing/testing.html> which has
166 all of the mod_perl-specific syntax and features have been ported to
167 PHP with this class.

170 "Apache-Test" is a community effort, maintained by a group of dedicated
