Apache::TestMM(3)

NAME
Apache::TestMM - Provide MakeMaker Wrapper Methods

SYNOPSIS
  require Apache::TestMM;

  # import MY::test and MY::clean overrides for MM
  Apache::TestMM->import(qw(test clean));

  # parse command line args
  Apache::TestMM::filter_args();

  # autogenerate the script
  Apache::TestMM::generate_script('t/TEST');

DESCRIPTION
"Apache::TestMM" provides wrappers for the "ExtUtils::MakeMaker" craft, making it easier to extend the autogenerated Makefile with "Apache::Test".

FUNCTIONS

  "import"
  use Apache::TestMM qw(test clean);

or:

  Apache::TestMM->import(qw(test clean));

Imports "MY::" overrides for the default "ExtUtils::MakeMaker" test and clean targets, as if you have defined:

  sub MY::test {...}
  sub MY::clean {...}

in Makefile.PL. "Apache::TestMM" does this for you so that these Makefile targets will run the Apache server and the tests for it, and clean up after its mess.

  "filter_args"
  push @ARGV, '-apxs', $apxs_path;
  Apache::TestMM::filter_args();
  WriteMakefile(...);

When WriteMakefile() is called it parses @ARGV, hoping to find special options like "PREFIX=/home/stas/perl". "Apache::Test" accepts a lot of configuration options of its own. When Apache::TestMM::filter_args() is called, it removes any "Apache::Test"-specific options from @ARGV and stores them internally, so when WriteMakefile() is called they aren't in @ARGV and thus won't be processed by WriteMakefile().

The options can be set when Makefile.PL is called:

  % perl Makefile.PL -apxs /path/to/apxs

Or you can push them manually to @ARGV from the code:

  push @ARGV, '-apxs', $apxs_path;

When:

  Apache::TestMM::generate_script('t/TEST');

is called, "Apache::Test"-specific options extracted by Apache::TestMM::filter_args() are written to the autogenerated file. In our example, the autogenerated t/TEST will include:

  %Apache::TestConfig::Argv = qw(apxs /path/to/apxs);

which is going to be used by the "Apache::Test" runtime.

The other frequently used options are: "-httpd", telling where to find the httpd (usually when the "-apxs" option is not used), "-libmodperl" to use a specific mod_perl shared object (if your mod_perl is built as DSO), "-maxclients" to change the default number of the configured "MaxClients" directive, "-port" to start the server on a specific port, etc. To get the complete list of available configuration options and their purpose and syntax, run:

  % perl -MApache::TestConfig -le 'Apache::TestConfig::usage()'

You may wish to document some of these in your application's README file, especially the "-apxs" and "-httpd" options.

  "generate_script"
  Apache::TestMM::generate_script('t/TEST');

generate_script() accepts the name of the script to generate and will look for a template with the same name and suffix .PL. So in our example it'll look for t/TEST.PL. The autogenerated script t/TEST will include the contents of t/TEST.PL, and special directives, including any configuration options passed via filter_args() called from Makefile.PL, special fixup code, etc.
