Test only EJB
It’s not a real application server
Webservices: Apache CXF
JMS: Apache MQ
JPA: OpenJPA
Hibernate
(any provider)

The aliens have landed
• Arquillian is a testing framework
• There are runners…
• Containers…
• & Enrichers
– glue layer between
your code and
the container:
inject, track results

A natural evolution

44. twitter: @kubem
The are three modes
• Embedded
– You run your app server together with your code, in a
single JVM
• Managed
– Arquillian starts and stops your nodes, together with an
app, in separate JVMs
• Remote
– Everything is remotly deployed

45. twitter: @kubem
And four ways for
communicating results
• Local
– Same JVM, local bindings
• Servlet 2.5
– Pre JEE-6 containers
• Servlet 3.0
– Leveraging async servlets
• JMX
– Jboss AS 7 way

46. How it works in practice

47. twitter: @kubem
Why we do it?
• Real test with real services (no mocks
movement)
• With real environment
• Short feedback cycle

48. twitter: @kubem
What’s next
• Persitence Extension (DBUnit)
• GWT Extension
• JSFUnit
• BPEL testing
• Performance
• … ?

You can innovate on
nonfunctional areas, such as
devops, logging, metrics, etc, if
your core business needs to be
more conservative.

54. twitter: @kubem
Innovation comes not just from
using new technologies, but also
from using new techniques with
old boring technologies
