The invocation ends with a return (message 1.6). After that, the controller sets the id, name and age to the account object (message 1.2, 1.3, 1.4) and adds itself to the account list (message: 1.5). When a person invokes RegisterController's register method (message: 1), it creates an account object (message: 1.1). Click Finish button.Īs a result, a UML sequence diagram is formed. The Create new sequence diagram option is selected and diagram name is entered by default.
You need to select a diagram to visualize the interaction. Select src > RegisterController.java > register (String,int). Select the extracted source folder src. In the Instant Reverse Java to Sequence Diagram window, click on Add Source Folder. 
Select Tools > Code > Instant Reverse Java to Sequence Diagram. In the New Project window, enter Account Registration as project name and click Create Blank Project. Create a new project by selecting Project > New from the application toolbar. You can edit this template and create your own diagram. Read the register method in RegisterController.java to see how it works. Use Creately’s easy online diagram editor to edit this diagram, collaborate with others and export results to multiple image formats. Download Sample.zip of this tutorial and extract the zip file to any directory. In this way, the diagram describes the whole feature working properly, and it becomes simple to identify which parts of the whole are missing, and create tasks to implement them. Extras such as acceptance criteria can then also be added. That feature can be described and then fully captured (end-to-end) in the sequence diagram, including all relevant information, such as messaging protocols, validation points, etc. Additionally, when presented with a clean diagram, the participants tend to see what is missing rather than needing to wait for it to be discovered later, and block execution.Ī story should be a single feature. This way, everyone's input can be captured and agreement made while they are still discussing it. 
The simplicity of shared creating/editing diagrams provided by this tool, means it is now possible to create a sequence diagram during the planning meeting, rather than set it aside as a separate task in itself. The clean separation provided by the diagram actors immediately helps decompose the story in tasks and increase visibility.
So, I am pushing the use of sequence diagrams as the single graphic needed to capture and think about an agile story. UML diagrams are a powerful way to encapsulate and communicate information. We need a more rigorous way to communicate the details in our projects. Everyone thinks they understand what everyone else is saying. It's what you know, that just ain't so.Ī trite way of saying assumptions will break you, and when it comes to projects and communication, assumptions are rife. WARNING: this is still in development, so some parts are unfinished, eg: help. Generate UML diagrams from text, including: Sequence, Activity, Class, State, Component.
