Apache::TestRun(3pm)  User Contributed Perl Documentation Apache::TestRun(3pm)



NAME
       Apache::TestRun - Run the test suite

SYNOPSIS
DESCRIPTION
       The "Apache::TestRun" package controls the configuration and running of
       the test suite.

METHODS
       Several methods are sub-classable, if the default behavior should be
       changed.

   "bug_report"
       The "bug_report()" method is executed when "t/TEST" was executed with
       the "-bugreport" option, and "make test" (or "t/TEST") fail. Normally
       this is callback which you can use to tell the user how to deal with
       the problem, e.g. suggesting to read some document or email some
       details to someone who can take care of it. By default nothing is
       executed.

       The "-bugreport" option is needed so this feature won't become annoying
       to developers themselves. It's automatically added to the "run_tests"
       target in Makefile. So if you repeateadly have to test your code, just
       don't use "make test" but run "t/TEST" directly. Here is an example of
       a custom "t/TEST"

         My::TestRun->new->run(@ARGV);

         package My::TestRun;
         use base 'Apache::TestRun';

         sub bug_report {
             my $self = shift;

             print <<EOI;
         +--------------------------------------------------------+
         | Please file a bug report: http://perl.apache.org/bugs/ |
         +--------------------------------------------------------+
         EOI
         }

   "pre_configure"
       The "pre_configure()" method is executed before the configuration for
       "Apache::Test" is generated. So if you need to adjust the setup before
       httpd.conf and other files are autogenerated, this is the right place
       to do so.

       For example if you don't want to inherit a LoadModule directive for
       mod_apreq.so but to make sure that the local version is used, you can
       sub-class "Apache::TestRun" and override this method in t/TEST.PL:

         package My::TestRun;
         use base 'Apache::TestRun';
         use Apache::TestConfig;
         __PACKAGE__->new->run(@ARGV);

         sub pre_configure {
             my $self = shift;
             # Don't load an installed mod_apreq
             Apache::TestConfig::autoconfig_skip_module_add('mod_apreq.c');

             $self->SUPER::pre_configure();
         }

       Notice that the extension is .c, and not .so.

       Don't forget to run the super class' c<pre_configure()> method.

   "new_test_config"
       META: to be completed

Persistent Custom Configuration
       When "Apache::Test" is first installed or used, it will save the values
       of "httpd", "apxs", "port", "user", and "group", if set, to a
       configuration file "Apache::TestConfigData".  This information will
       then be used in setting these options for subsequent uses of
       "Apache-Test" unless temprorarily overridden, either by setting the
       appropriate environment variable ("APACHE_TEST_HTTPD",
       "APACHE_TEST_APXS", "APACHE_TEST_PORT", "APACHE_TEST_USER", and
       "APACHE_TEST_GROUP") or by giving the relevant option ("-httpd",
       "-apxs", "-port", "-user", and "-group") when the "TEST" script is run.

       To avoid either using previous persistent configurations or saving
       current configurations, set the "APACHE_TEST_NO_STICKY_PREFERENCES"
       environment variable to a true value.

       Finally it's possible to permanently override the previously saved
       options by passing "-save".

       Here is the algorithm of how and when options are saved for the first
       time and when they are used. We will use a few variables to simplify
       the pseudo-code/pseudo-chart flow:

       $config_exists - custom configuration has already been saved, to get
       this setting run "custom_config_exists()", which tests whether either
       "apxs" or "httpd" values are set. It doesn't check for other values,
       since all we need is "apxs" or "httpd" to get the test suite running.
       custom_config_exists() checks in the following order
       lib/Apache/TestConfigData.pm (if during Apache-Test build) ,
       ~/.apache-test/Apache/TestConfigData.pm and Apache/TestConfigData.pm in
       the perl's libraries.

       $config_overriden - that means that we have either "apxs" or "httpd"
       values provided by user, via env vars or command line options.

       1 Building Apache-Test or modperl-2.0 (or any other project that
       bundles Apache-Test).
             1) perl Apache-Test/Makefile.PL
             (for bundles top-level Makefile.PL will run this as well)

             if $config_exists
                 do nothing
             else
                 create lib/Apache/TestConfigData.pm w/ empty config: {}

             2) make

             3) make test

             if $config_exists
                 if $config_overriden
                     override saved options (for those that were overriden)
                 else
                     use saved options
             else
                 if $config_overriden
                     save them in lib/Apache/TestConfigData.pm
                     (which will be installed on 'make install')
                 else
                     - run interactive prompt for C<httpd> and optionally for C<apxs>
                     - save the custom config in lib/Apache/TestConfigData.pm
                     - restart the currently run program

             modperl-2.0 is a special case in (3). it always overrides 'httpd'
             and 'apxs' settings. Other settings like 'port', can be used from
             the saved config.

             4) make install

                if $config_exists only in lib/Apache/TestConfigData.pm
                   it will be installed system-wide
                else
                   nothing changes (since lib/Apache/TestConfigData.pm won't exist)

       2 Testing 3rd party modules (after Apache-Test was installed)
           Notice that the following situation is quite possible:

             cd Apache-Test
             perl Makefile.PL && make install

           so that Apache-Test was installed but no custom configuration saved
           (since its "make test" wasn't run). In which case the interactive
           configuration should kick in (unless config options were passed)
           and in any case saved once configured.

           $custom_config_path - perl's Apache/TestConfigData.pm (at the same
           location as Apache/TestConfig.pm) if that area is writable by that
           user (e.g. perl's lib is not owned by 'root'). If not, in
           ~/.apache-test/Apache/TestConfigData.pm.

             1) perl Apache-Test/Makefile.PL
             2) make
             3) make test

             if $config_exists
                 if $config_overriden
                     override saved options (for those that were overriden)
                 else
                     use saved options
             else
                 if $config_overriden
                     save them in $custom_config_path
                 else
                     - run interactive prompt for C<httpd> and optionally for C<apxs>
                     - save the custom config in $custom_config_path
                     - restart the currently run program

             4) make install

   Saving Custom Configuration Options
       If you want to override the existing custom configurations options to
       "Apache::TestConfigData", use the "-save" flag when running "TEST".

       If you are running "Apache::Test" as a user who does not have
       permission to alter the system "Apache::TestConfigData", you can place
       your own private configuration file TestConfigData.pm under
       "$ENV{HOME}/.apache-test/Apache/", which "Apache::Test" will use, if
       present. An example of such a configuration file is

         # file $ENV{HOME}/.apache-test/Apache/TestConfigData.pm
         package Apache::TestConfigData;
         use strict;
         use warnings;
         use vars qw($vars);

         $vars = {
             'group' => 'me',
             'user' => 'myself',
             'port' => '8529',
             'httpd' => '/usr/local/apache/bin/httpd',

         };
         1;
