NAME

6       Test2::Workflow - A test workflow is a way of structuring tests using
7       composable units.
8

DESCRIPTION

10       A test workflow is a way of structuring tests using composable units. A
11       well known example of a test workflow is RSPEC <http://rspec.info/>.
12       RSPEC is implemented using Test2::Workflow in Test2::Tools::Spec along
13       with several extensions.
14

IMPORTANT CONCEPTS

16   BUILD
17       Test2::Workflow::Build
18
19       A Build is used to compose tasks. Usually a build object is pushed to
20       the stack before running code that adds tasks to the build. Once the
21       build sub is complete the build is popped and returned. Usually a build
22       is converted into a root task or task group.
23
24   RUNNER
25       Test2::Workflow::Runner
26
27       A runner takes the composed tasks and executes them in the proper
28       order.
29
30   TASK
31       Test2::Workflow::Task
32
33       A task is a unit of work to accomplish. There are 2 main types of task.
34
35       ACTION
36
37       An action is the most simple unit used in composition. An action is
38       essentially a name and a codeblock to run.
39
40       GROUP
41
42       A group is a task that is composed of other tasks.
43

EXPORTS

45       All exports are optional, you must request the ones you want.
46
47       $parsed = parse_args(args => \@args)
48       $parsed = parse_args(args => \@args, level => $L)
49       $parsed = parse_args(args => \@args, caller => [caller($L)])
50           This will parse a "typical" task builders arguments. The @args
51           array MUST contain a name (plain scalar containing text) and also a
52           single CODE reference.  The @args array MAY also contain any
53           quantity of line numbers or hashrefs.  The resulting data structure
54           will be a single hashref with all the provided hashrefs squashed
55           together, and the 'name', 'code', 'lines' and 'frame' keys set from
56           other arguments.
57
58               {
59                   # All hashrefs from @args get squashed together:
60                   %squashed_input_hashref_data,
61
62                   # @args must have exactly 1 plaintext scalar that is not a number, it
63                   # is considered the name:
64                   name => 'name from input args'
65
66                   # Integer values are treated as line numbers
67                   lines => [ 35, 44 ],
68
69                   # Exactly 1 coderef must be provided in @args:
70                   code => \&some_code,
71
72                   # 'frame' contains the 'caller' data. This may be passed in directly,
73                   # obtained from the 'level' parameter, or automatically deduced.
74                   frame => ['A::Package', 'a_file.pm', 42, ...],
75               }
76
77       $build = init_root($pkg, %args)
78           This will initialize (or return the existing) a build for the
79           specified package. %args get passed into the Test2::Workflow::Build
80           constructor.  This uses the following defaults (which can be
81           overridden using %args):
82
83               name    => $pkg,
84               flat    => 1,
85               iso     => 0,
86               async   => 0,
87               is_root => 1,
88
89           Note that %args is completely ignored if the package build has
90           already been initialized.
91
92       $build = root_build($pkg)
93           This will return the root build for the specified package.
94
95       $build = current_build()
96           This will return the build currently at the top of the build stack
97           (or undef).
98
99       $build = build($name, \%params, sub { ... })
100           This will push a new build object onto the build stash then run the
101           provided codeblock. Once the codeblock has finished running the
102           build will be popped off the stack and returned.
103
104           See parse_args() for details about argument processing.
