Java EE
Team Skills

JBoss,
Open Source
MySQL


What does agile mean anyway?
• Shared knowledge / Transparency
• Everyone can contribute to their full potential
• Everyone can take Responsibility and Commit
to Goals
So we need:
=> Transparent Requirements
=> Transparent Project Status


BPMN 2.0 is agile ;-)

BPEL is not

Everyone needs Access to the Technical
Model. What’s Your Dream Tool?

JBOSS AS7 as Runtime Environment
• From self Contained to everything is provided
– JPA 2.0, JAX-RS, Guava, Apache Commons, CDI,..
might be good enough
• Open Source (really!)
• Useful Architecture to start from
• Fox adds Activiti in a sensible way

So hopefully I convinced You
…that the fox additions to Activiti make it even
more suitable for agile Projects

Mockito…

Test Strategy

• Maximize Coverage of Item Under Test
• Start with Happy Path Test


Shrinkwarp does bpmn20

Goal: Replace Sub process with Mock Process
Shrinkwarp defines the Deployment Unit:

Replace Sub process


Mocking with Delegates
Simple Mock Process

EL Injected Mock Delegate


Preparing the Test with Mockito


Assert the actual process flow with
Mockito


Java CDI Magic – compare this with
BPEL, XPATH, XQUERY

@Inject
private BusinessProcess businessProcess;


Contextual Business Process Managemet


What about transparent project

DONE = it’s tested

Answer:
We can use all state of the Art stuff we
already know.
