Business Workflow
A Business Workflow is a sequence of steps that an end user performs with the application under test. Typically, one would assert or verify something about the system after some actions are performed.
A Business Workflow has an underlying code associated with it. The actual mechanics of driving the application is done in the code.
Create Business Workflow
Workflows are represented in the scenario editor as a bulleted list. If a workflow step fails when a scenario is executed, the execution of that scenario stops and the scenario execution is marked as failed.
It is advisable to specify the workflow steps in a way that is not closely tied to the underlying user interface of the application, as this can make the scenario fragile.
Workflow steps can be parameterized by passing data within quotes. The parameters can be moved around by Rephrasing the workflow steps.
Rename Business Workflow
Rename is an operation available on the Business Workflow. This essentially renames the workflow and makes corresponding changes to the underlying class names.
Using Content Assist
Twist provides the Content Assist option at various places on using Ctrl+Space. This will list all the possible options available at that point.
While using Content Assist the list drawn will contain a list of available workflow steps project-wide. These steps can be further filtered based on the text typed in and on choosing the step, the workflow containing the step itself is added onto the scenario.
Generate Code using Quick Assists
Create Method Quick Assist which is invoked by Ctrl+1 and by pressing Return, or by selecting QuickFix from the context menu will create a new stub method in the corresponding class.
Create Stub Methods and Classes
Twist generates stub methods and classes for the workflow steps created. The option Quick Assist is used to get Twist to create code when it does not yet exist. It is invoked by Ctrl-1 or by selecting Quick Fix from the context menu.
Refactoring
Rephrase Workflow Steps
The Rephrase Step in Twist is a combination of Rename and Change Method Signature. This option can be accessed through the context menu.
This option allows the user to
- modify the name of a workflow step
- change the order of parameters
- add a parameter
- remove a parameter
Once any or all these changes are performed it can be noticed that the workflow step has been updated in both the scenario as well as the Java code.
Extract Concept
The Extract Concept in Twist is a specific operation that allows a user to group and reuse a set of workflow steps.
The selected workflow steps are grouped as one concept and are replaced by the name of the concept as a workflow step.
In the underlying code, it can be noticed that the grouped steps are included in a new method with the same name as the newly created concept.
