  =head1 NAME
  
  Apache::TestRunPHP - configure and run a PHP-based test suite
  
  =head1 SYNOPSIS
  
    use Apache::TestRunPHP;
    Apache::TestRunPHP->new->run(@ARGV);
  
  =head1 DESCRIPTION
  
  The C<Apache::TestRunPHP> package controls the configuration and
  running of the test suite for PHP-based tests.  It's a subclass
  of C<Apache::TestRun> and similar in function to C<Apache::TestRunPerl>.
  
  Refer to the C<Apache::TestRun> manpage for information on the
  available API.
  
  =head1 EXAMPLE
  
  C<TestRunPHP> works almost identially to C<TestRunPerl>, but in
  case you are new to C<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.
  
  because C<Apache-Test> is a Perl-based testing framework we start
  from a C<Makefile.PL>, which should have the following lines (in
  addition to the standard C<Makefile.PL> parts):
  
    use Apache::TestMM qw(test clean);
    use Apache::TestRunPHP ();
  
    Apache::TestMM::filter_args();
  
    Apache::TestRunPHP->generate_script();
  
  C<generate_script()> will create a script named C<t/TEST>, the gateway
  to the Perl testing harness and what is invoked when you call
  C<make test>.  C<filter_args()> accepts some C<Apache::Test>-specific
  arguments and passes them along.  for example, to point to a specific
  C<httpd> installation you would invoke C<Makefile.PL> as follows
  
    $ perl Makefile.PL -httpd /my/local/apache/bin/httpd
  
  and C</my/local/apache/bin/httpd> will be propagated throughout the
  rest of the process.
  
  now, like with C<Apache::TestRun> and C<Apache::TestRunPerl>, you can
  place client-side Perl test scripts under C<t/>, such as C<t/01basic.t>,
  and C<Apache-Test> will run these scripts when you call C<make test>.
  however, what makes C<Apache::TestRunPHP> unique is some added magic
  specifically tailored to a PHP environment.  here are the mechanics.
  
  C<Apache::TestRunPHP> will look for PHP test scripts in that match
  the following pattern
  
    t/response/TestFoo/bar.php
  
  where C<Foo> and C<bar> can be anything you like, and C<t/response/Test*>
  is case sensitive.  when this format is adhered to, C<Apache::TestRunPHP>
  will create an associated Perl test script called C<t/foo/bar.t>, which
  will be executed when you call C<make test>.  all C<bar.t> does is issue
  a simple GET to C<bar.php>, leaving the actual testing to C<bar.php>.  in
  essence, you can forget that C<bar.t> even exists.
  
  what does C<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 C<Apache::Test> calls
  C<bar.php> it feeds the results directly to C<Test::Harness>, a module
  that comes with every Perl installation, and C<Test::Harness> expects
  what it receives to be formated in a very specific way.  by itself, all
  of this is pretty useless, so C<Apache::Test> provides PHP testers with
  something much better.  here is a much better example:
  
    <?php
      // import the Test::More emulation layer
      // see
      //   http://www.perldoc.com/perl5.8.4/lib/Test/More.html
      // for more information
      require '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 C<more.php> is automatically generated by
  C<Apache::TestConfigPHP> and configurations tweaked in such a
  a way that your PHP scripts can find it without issue.  the 
  functions provided by C<more.php> are equivalent in name and
  function to those in C<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 C<Makefile.PL> to configure Apache for us, and
  a PHP script in C<t/response/TestFoo/bar.php> to send some 
  results out to the testing engine.  issuing C<make test>
  would start Apache, issue the request to C<bar.php>, generate
  a report, and shut down Apache.  the report would look like 
  something like this
  
    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
