A single TomEE ApplicationComposer instance for all your tests!

TomEE ApplicationComposer is a nice solution for embedded EE testing. The goal is to describe its application in Java and deploy this model. However it starts OpenEJB and deploys/undeploys the application either by class or method depending the setup.

When this feature can be insane for small deployments which would benefit of an insanely easy configuration and simple mock solution it can be an issue for application deploying again and again the same model.

To avoid that the coming TomEE 7.0.0-M2 provides a new JUnit runner but you can already benefit from it with a single class!

OpenEJB 5 + Groovy = service done fast!

If you read the previous post I wrote about ApplicationComposers run method you surely wonder what a service could look like using groovy and @Grab to resolve maven dependencies?

Here is a quick post showing it:

Did you ever realize OpenEJB ApplicationComposers is the EE Spring boot?

I spoke a lot of ApplicationComposers on this blog. If you don’t know it yet in two words it is originally a way to fully define its EE application programmatically and then run test against this described application.

However with a trivial main you can make it run your application!
