NAME

6       Apache::TestRunPHP - configure and run a PHP-based test suite
7

SYNOPSIS

9         use Apache::TestRunPHP;
10         Apache::TestRunPHP->new->run(@ARGV);
11

DESCRIPTION

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
17       Refer to the "Apache::TestRun" manpage for information on the available
18       API.

EXAMPLE

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
26       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
30         use Apache::TestMM qw(test clean);
31         use Apache::TestRunPHP ();
32
33         Apache::TestMM::filter_args();
34
35         Apache::TestRunPHP->generate_script();
36
37       "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
43         $ perl Makefile.PL -httpd /my/local/apache/bin/httpd
44
45       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
53       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
59       "Apache::TestRunPHP" will look for PHP test scripts in that match the
60       following pattern
61
62         t/response/TestFoo/bar.php
63
64       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
72       what does "bar.php" look like?  here is an example:
73
74         <?php
75           print "1..1\n";
76           print "ok 1\n"
77         ?>
78
79       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
89         <?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
97           # plan() the number of tests
98           plan(6);
99
100           # 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
104           # 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
110           diag("printing some debugging information");
111
112           # whoops! one too many tests.  I wonder what will happen...
113           is ('biff', 'biff', 'baz is a baz');
114         ?>
115
116       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
123       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
131         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         -------------------------------------------------------------------------------
148         t/php/bar.t                6    3  50.00%  2 4 7
149         Failed 1/1 test scripts, 0.00% okay. 1/6 subtests failed, 83.33% okay.
150
151       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
156       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...

SEE ALSO

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.
