NAME

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

DESCRIPTION

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

IMPORTANT CONCEPTS

   BUILD
       Test2::Workflow::Build

       A Build is used to compose tasks. Usually a build object is pushed to the stack before
       running code that adds tasks to the build. Once the build sub is complete the build is
       popped and returned. Usually a build is converted into a root task or task group.

   RUNNER
       Test2::Workflow::Runner

       A runner takes the composed tasks and executes them in the proper order.

   TASK
       Test2::Workflow::Task

       A task is a unit of work to accomplish. There are 2 main types of task.

       ACTION

       An action is the most simple unit used in composition. An action is essentially a name and
       a codeblock to run.

       GROUP

       A group is a task that is composed of other tasks.

EXPORTS

       All exports are optional, you must request the ones you want.

       $parsed = parse_args(args => \@args)
       $parsed = parse_args(args => \@args, level => $L)
       $parsed = parse_args(args => \@args, caller => [caller($L)])
           This will parse a "typical" task builders arguments. The @args array MUST contain a
           name (plain scalar containing text) and also a single CODE reference.  The @args array
           MAY also contain any quantity of line numbers or hashrefs.  The resulting data
           structure will be a single hashref with all the provided hashrefs squashed together,
           and the 'name', 'code', 'lines' and 'frame' keys set from other arguments.

               {
                   # All hashrefs from @args get squashed together:
                   %squashed_input_hashref_data,

                   # @args must have exactly 1 plaintext scalar that is not a number, it
                   # is considered the name:
                   name => 'name from input args'

                   # Integer values are treated as line numbers
                   lines => [ 35, 44 ],

                   # Exactly 1 coderef must be provided in @args:
                   code => \&some_code,

                   # 'frame' contains the 'caller' data. This may be passed in directly,
                   # obtained from the 'level' parameter, or automatically deduced.
                   frame => ['A::Package', 'a_file.pm', 42, ...],
               }

       $build = init_root($pkg, %args)
           This will initialize (or return the existing) a build for the specified package. %args
           get passed into the Test2::Workflow::Build constructor.  This uses the following
           defaults (which can be overridden using %args):

               name    => $pkg,
               flat    => 1,
               iso     => 0,
               async   => 0,
               is_root => 1,

           Note that %args is completely ignored if the package build has already been
           initialized.

       $build = root_build($pkg)
           This will return the root build for the specified package.

       $build = current_build()
           This will return the build currently at the top of the build stack (or undef).

       $build = build($name, \%params, sub { ... })
           This will push a new build object onto the build stash then run the provided
           codeblock. Once the codeblock has finished running the build will be popped off the
           stack and returned.

           See "parse_args()" for details about argument processing.
