Re: [virgo-dev] Jboss Migrating to Virgo

Actually the approach below would not work in the case of a fragment because the fragment needs to attach to the deployer bundle during kernel initialisation.

Lin: are you planning to write a fragment of the deployer bundle to start with? If so, we'll have to find a way to attach it to the deployer during initialisation of the kernel in the test environment.

Glyn

Ok. You could start to develop a testcase EarDeploymentTests by copying/changing ParDeploymentTests [1]. You could write your EAR deployer extension as a fragment of the deployer bundle and add it to a test repository configured in [2]. This would enable you to make progress without any changes to the kernel.

One way to collaborate would be for you to make these changes in your own fork of the kernel repository on github, probably on your own branch for ease of communication.

Then we committers could work on refactoring the kernel so that the deployer extension can become a regular (non-fragment) bundle which would be deployed at the start of the testcase. To synchronise your fork, you would pull our changes, merge them into your branch, and push the branch to github.

Does that sound reasonable?

Dmitry and other "soon to be committers": does that approach sound best to you or can you suggest something smoother?

Hi Glyn,

Yes, I'm very interested in these integration tests. And I'm still work on implementing the EAR deployer for Virgo.

Hi Lin

We discussed adding artifact types during the recent Virgo F2F. Dmitry has a proposal for refactoring the deployer to help in this.

One or more integration tests would really help to tie down the requirements, but I'm not sure who has the time+skills to write these. If that's something you may be interested in looking at, please say so! The tests would probably build some very simple EARs from source (using our build system) and then test the content appearing after deployment. These tests would of course fail without the necessary deployer extension. They could be made to pass by extending the deployer using a fragment (something that Dmitry has successfully managed in the past) and then the task before us would be to refactor the deployer so a non-fragment bundle could achieve the same effect using only public deployer/kernel APIs.

Regards,
Glyn
