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
@argsarray MUST contain a name (plain scalar containing text) and also a single CODE reference. The@argsarray 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 numberslines => [ 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.
%argsget 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
%argsis 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.
