.SH "NAME"
Test2::Workflow \- A test workflow is a way of structuring tests using
composable units.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
A test workflow is a way of structuring tests using composable units. A well
known example of a test workflow is <\s-1RSPEC\s0>. \s-1RSPEC\s0 is
implemented using Test2::Workflow in Test2::Tools::Spec along with several
extensions.
.SH "IMPORTANT CONCEPTS"
.IX Header "IMPORTANT CONCEPTS"
.SS "\s-1BUILD\s0"
.IX Subsection "BUILD"
Test2::Workflow::Build
.PP
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.
.SS "\s-1RUNNER\s0"
.IX Subsection "RUNNER"
Test2::Workflow::Runner
.PP
A runner takes the composed tasks and executes them in the proper order.
.SS "\s-1TASK\s0"
.IX Subsection "TASK"
Test2::Workflow::Task
.PP
A task is a unit of work to accomplish. There are 2 main types of task.
.PP
\fI\s-1ACTION\s0\fR
.IX Subsection "ACTION"
.PP
An action is the most simple unit used in composition. An action is essentially
a name and a codeblock to run.
.PP
\fI\s-1GROUP\s0\fR
.IX Subsection "GROUP"
.PP
A group is a task that is composed of other tasks.
.SH "EXPORTS"

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

This will parse a \*(L"typical\*(R" task builders arguments. The \f(CW@args\fR array \s-1MUST\s0
contain a name (plain scalar containing text) and also a single \s-1CODE\s0 reference.
The \f(CW@args\fR array \s-1MAY\s0 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.
.Sp
.Vb 3
\& {
\& # 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 => \*(Aqname from input args\*(Aq
\&
\& # Integer values are treated as line numbers
\& lines => [ 35, 44 ],
\&
\& # Exactly 1 coderef must be provided in @args:
\& code => \e&some_code,
\&
\& # \*(Aqframe\*(Aq contains the \*(Aqcaller\*(Aq data. This may be passed in directly,
\& # obtained from the \*(Aqlevel\*(Aq parameter, or automatically deduced.

.ie n .IP "$build = init_root($pkg, %args)" 4
.el .IP "\f(CW$build\fR = init_root($pkg, \f(CW%args\fR)" 4
.IX Item "$build = init_root($pkg, %args)"
This will initialize (or return the existing) a build for the specified
package. \f(CW%args\fR get passed into the Test2::Workflow::Build constructor.
This uses the following defaults (which can be overridden using \f(CW%args\fR):
.Sp
.Vb 5
\& name => $pkg,
\& flat => 1,
\& iso => 0,
\& async => 0,
\& is_root => 1,
.Ve
.Sp
Note that \f(CW%args\fR is completely ignored if the package build has already been
initialized.
.ie n .IP "$build = root_build($pkg)" 4
.el .IP "\f(CW$build\fR = root_build($pkg)" 4
.IX Item "$build = root_build($pkg)"
This will return the root build for the specified package.
.ie n .IP "$build = \fIcurrent_build()\fR" 4
.el .IP "\f(CW$build\fR = \fIcurrent_build()\fR" 4
.IX Item "$build = current_build()"
This will return the build currently at the top of the build stack (or undef).
.ie n .IP "$build = build($name, \e%params, sub { ... })" 4
.el .IP "\f(CW$build\fR = build($name, \e%params, sub { ... })" 4
.IX Item "$build = build($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.
