DESCRIPTION

22       This is a basic class for running workflows. This class is intended to
23       be subclasses for more fancy/feature rich workflows.
24

SYNOPSIS

26   SUBCLASS
27           package My::Runner;
28           use strict;
29           use warnings;
30
31           use parent 'Test::Stream::Workflow::Runner';
32
33           sub instance {
34               my $class = shift;
35               return $class->new(@_);
36           }
37
38           sub subtest {
39               my $self = shift;
40               my ($unit) = @_;
41               ...
42               return $bool
43           }
44
45           sub verify_meta {
46               my $self = shift;
47               my ($unit) = @_;
48               my $meta = $unit->meta || return;
49               warn "the 'foo' meta attribute is not supported" if $meta->{foo};
50               ...
51           }
52
53           sub run_task {
54               my $self = shift;
55               my ($task) = @_;
56               ...
57               $task->run();
58               ...
59           }
60
61   USE SUBCLASS
62           use Test::Stream qw/... Spec/;
63
64           use My::Runner; # Sets the runner for the Spec plugin.

METHODS

69   CLASS METHODS
70       $class->import()
71       $class->import(@instance_args)
72           The import method checks the calling class to see if it has an
73           Test::Stream::Workflow::Meta instance, if it does then it sets the
74           runner.  The runner that is set is the result of calling
75           "$class->instance(@instance_args)". The instance_args are optional.
76
77           If there is no meta instance for the calling class then import is a
78           no-op.
79
80       $bool = $class->subtests($unit)
81           This determines if the units should be run as subtest or flat. The
82           base class always returns true for this. This is a hook that allows
83           you to override the default behavior.
84
85       $runner = $class->instance()
86       $runner = $class->instance(@args)
87           This is a hook allowing you to construct an instance of your
88           runner. The base class simply returns the class name as it does not
89           need to be instansiated. If your runner needs to maintain state
90           then this can return a blessed instance.
91
92   CLASS AND/OR OBJECT METHODS
93       These are made to work on the class itself, but should also work just
94       fine on a blessed instance if your subclass needs to be instantiated.
95
96       $runner->verify_meta($unit)
97           This method reads the "$unit->meta" hash and warns about any
98           unrecognised keys. Your subclass should override this if it wants
99           to add support for any meta-keys.
100
101       $runner->run(unit => $unit, args => $arg)
102       $runner->run(unit => $unit, args => $arg, no_final => $bool)
103           Tell the runner to run a unit with the specified args. The args are
104           optional.  The "no_final" arg is optional, it should be used on
105           support units that should not produce final results (or be a
106           subtest of their own).
107
108       $runner->run_task($task)
109           This simply calls "$task->run()". It is mainly here for subclasses
110           to override.
