=head1 NAME
WebGUI::Test::Maker::Permission -- Test::Maker subclass for WebGUI Permissions
=head1 SYNOPSIS
use Test::More;
use WebGUI::Test::Maker::Permission;
my $maker = WebGUI::Test::Maker::Permission->new();
$maker->prepare({
object => WebGUI::Asset->new,
method => "canView",
pass => [userId, userId],
fail => [userId, userId],
});
plan tests => $maker->plan;
$maker->run;
=head1 DESCRIPTION
Test generator for testing WebGUI permissions. WebGUI permissions subroutines
take a single argument (a userId), or they use the default user from the
current session. They return true if the user has permission, or false
otherwise.
This module tests permissions subroutines by running a list of userIds that
should either pass or fail the permissions.
=head1 DEPENDS
This module depends on

=head1 METHODS
=head2 new
Create a new WebGUI::Test::Maker::Permission object.
=cut
=head2 get
Get a setting. See C<set> for a list of settings.
=cut
#----------------------------------------------------------------------------
=head2 plan
Returns the number of tests currently prepared. This module runs two tests
for each userId in either the C<pass> or C<fail> keys of the C<prepare()>
hash reference.
=cut
sub plan {
my $self = shift;

for my $test ( @{$self->{_tests}} ) {
if ($test->{pass}) {
$plan += @{$test->{pass}} * 2;
}
if ($test->{fail}) {
$plan += @{$test->{fail}} * 2;
}
}
return $plan;
}
#----------------------------------------------------------------------------
=head2 plan_per_test
Returns undef. There is no way to pre-calculate how many tests this will run
=cut
sub plan_per_test {
return undef;
}
#----------------------------------------------------------------------------
=head2 prepare
Prepare a test(s). Returns the object for convenience. The following keys
are required:
=over 4
=item object
An instanciated object to work on.
=item className
The class name of a module to work on. This would be useful for class methods.
=item method
The permissions method to test
=item pass
An array reference of userIds or WebGUI::User objects that should pass the
permissions test. If each user has a username, it will be used in the
test comment output instead of the userId.
=item fail
An array reference of userIds or WebGUI::User objects that should fail the
permissions test. If each user has a username, it will be used in the
test comment output instead of the userId.
=back
There are no optional parameters.

=head2 set
Set a setting.

=cut
#----------------------------------------------------------------------------
=head2 runUsers
Process an array of users for tests.
=head3 session
A WebGUI session object, used to access and/or alter the default session
user for the tests.
=head3 object
A WebGUI object or class, used for testing.
=head3 method
The method on the object or class to call for each test.
=head3 precedingArguments
Any arguments that should be pushed onto the argument list before a userId.
=head3 users
An array ref of users.
=head3 passing
A boolean, which if true, says that the users are expected to pass each test.
If false, the users will be expected to fail, which means that if they do
fail that the test itself will pass.
=head3 comment
A specific comment to add to the test's comment. Usually this would
be something like the username or userId.
