NAME

Test::Stream::Workflow::Runner - Simple runner for workflows.

EXPERIMENTAL CODE WARNING

This module is still EXPERIMENTAL. Test-Stream is now stable, but this particular module is still experimental. You are still free to use this module, but you have been warned that it may change in backwords incompatible ways. This message will be removed from this modules POD once it is considered stable.

DESCRIPTION

This is a basic class for running workflows. This class is intended to be subclasses for more fancy/feature rich workflows.

SYNOPSIS

SUBCLASS

    package My::Runner;
    use strict;
    use warnings;

    use parent 'Test::Stream::Workflow::Runner';

    sub instance {
        my $class = shift;
        return $class->new(@_);
    }

    sub subtest {
        my $self = shift;
        my ($unit) = @_;
        ...
        return $bool
    }

    sub verify_meta {
        my $self = shift;
        my ($unit) = @_;
        my $meta = $unit->meta || return;
        warn "the 'foo' meta attribute is not supported" if $meta->{foo};
        ...
    }

    sub run_task {
        my $self = shift;
        my ($task) = @_;
        ...
        $task->run();
        ...
    }

USE SUBCLASS

    use Test::Stream qw/... Spec/;

    use My::Runner; # Sets the runner for the Spec plugin.

    ...

METHODS

CLASS METHODS

$class->import()

$class->import(@instance_args)

The import method checks the calling class to see if it has an Test::Stream::Workflow::Meta instance, if it does then it sets the runner. The runner that is set is the result of calling $class->instance(@instance_args). The instance_args are optional.

If there is no meta instance for the calling class then import is a no-op.

$bool = $class->subtests($unit)

This determines if the units should be run as subtest or flat. The base class always returns true for this. This is a hook that allows you to override the default behavior.

$runner = $class->instance()

$runner = $class->instance(@args)

This is a hook allowing you to construct an instance of your runner. The base class simply returns the class name as it does not need to be instansiated. If your runner needs to maintain state then this can return a blessed instance.

CLASS AND/OR OBJECT METHODS

These are made to work on the class itself, but should also work just fine on a blessed instance if your subclass needs to be instantiated.

$runner->verify_meta($unit)

This method reads the $unit->meta hash and warns about any unrecognised keys. Your subclass should override this if it wants to add support for any meta-keys.

$runner->run(unit => $unit, args => $arg)

$runner->run(unit => $unit, args => $arg, no_final => $bool)

Tell the runner to run a unit with the specified args. The args are optional. The no_final arg is optional, it should be used on support units that should not produce final results (or be a subtest of their own).

$runner->run_task($task)

This simply calls $task->run(). It is mainly here for subclasses to override.
