App::Prove(3pm)        Perl Programmers Reference Guide        App::Prove(3pm)

NAME
       App::Prove - Implements the "prove" command.

VERSION
       Version 3.17

DESCRIPTION
       Test::Harness provides a command, "prove", which runs a TAP based test
       suite and prints a report. The "prove" command is a minimal wrapper
       around an instance of this module.

SYNOPSIS
           use App::Prove;

           my $app = App::Prove->new;
           $app->process_args(@ARGV);
           $app->run;

METHODS
   Class Methods
       "new"

       Create a new "App::Prove". Optionally a hash ref of attribute
       initializers may be passed.

       "state_class"

       Getter/setter for the name of the class used for maintaining state.
       This class should either subclass from "App::Prove::State" or provide
       an identical interface.

       "state_manager"

       Getter/setter for the instance of the "state_class".

       "add_rc_file"

           $prove->add_rc_file('myproj/.proverc');

       Called before "process_args" to prepend the contents of an rc file to
       the options.

       "process_args"

           $prove->process_args(@args);

       Processes the command-line arguments. Attributes will be set
       appropriately. Any filenames may be found in the "argv" attribute.

       Dies on invalid arguments.

       "run"

       Perform whatever actions the command line args specified. The "prove"
       command line tool consists of the following code:

           use App::Prove;

           my $app = App::Prove->new;
           $app->process_args(@ARGV);
           exit( $app->run ? 0 : 1 );  # if you need the exit code

       "require_harness"

       Load a harness replacement class.

         $prove->require_harness($for => $class_name);

       "print_version"

       Display the version numbers of the loaded TAP::Harness and the current
       Perl.

   Attributes
       After command line parsing the following attributes reflect the values
       of the corresponding command line switches. They may be altered before
       calling "run".

       "archive"
       "argv"
       "backwards"
       "blib"
       "color"
       "directives"
       "dry"
       "exec"
       "extension"
       "failures"
       "comments"
       "formatter"
       "harness"
       "ignore_exit"
       "includes"
       "jobs"
       "lib"
       "merge"
       "modules"

       "warnings_fail"
       "warnings_warn"

PLUGINS
       "App::Prove" provides support for 3rd-party plugins.  These are
       currently loaded at run-time, after arguments have been parsed (so you
       can not change the way arguments are processed, sorry), typically with
       the "-Pplugin" switch, eg:

         prove -PMyPlugin

       This will search for a module named "App::Prove::Plugin::MyPlugin", or
       failing that, "MyPlugin".  If the plugin can't be found, "prove" will
       complain & exit.

       You can pass an argument to your plugin by appending an "=" after the
       plugin name, eg "-PMyPlugin=foo".  You can pass multiple arguments
       using commas:

         prove -PMyPlugin=foo,bar,baz

       These are passed in to your plugin's "load()" class method (if it has
       one), along with a reference to the "App::Prove" object that is
       invoking your plugin:

         sub load {
             my ($class, $p) = @_;

             my @args = @{ $p->{args} };
             # @args will contain ( 'foo', 'bar', 'baz' )
             $p->{app_prove}->do_something;
             ...
         }

       Note that the user's arguments are also passed to your plugin's
       "import()" function as a list, eg:

         sub import {
             my ($class, @args) = @_;
             # @args will contain ( 'foo', 'bar', 'baz' )
             ...
         }

       This is for backwards compatibility, and may be deprecated in the
       future.

   Sample Plugin
       Here's a sample plugin, for your reference:

         package App::Prove::Plugin::Foo;

         # Sample plugin, try running with:
         # prove -PFoo=bar -r -j3
         # prove -PFoo -Q
         # prove -PFoo=bar,My::Formatter

         use strict;
         use warnings;

         sub load {
             my ($class, $p) = @_;
             my @args = @{ $p->{args} };
             my $app  = $p->{app_prove};

             print "loading plugin: $class, args: ", join(', ', @args ), "\n";

             # turn on verbosity
             $app->verbose( 1 );

             # set the formatter?
             $app->formatter( $args[1] ) if @args > 1;

             # print some of App::Prove's state:
             for my $attr (qw( jobs quiet really_quiet recurse verbose )) {
                 my $val = $app->$attr;
                 $val    = 'undef' unless defined( $val );
                 print "$attr: $val\n";
             }

             return 1;
         }

         1;
