NAME
App::Prove - Implements the “prove” command.
VERSION
Version 3.43
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
.

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
=-P=/=plugin=/ 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 );
some of App::Proves 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;
