Multi-module maven project with multiple WARs

[nilspreusker]

Hi, I have a conceptual question about testing a multi-module maven project with multiple WARs that interact via REST.

Let's picture a simple demo use-case where we have two WARs, war-1 and war-2. War-1 provides a REST API:

* HTTP POST /war-1/rest/war1

When this is called, in turn it makes a REST call to war-2:

* HTTP POST /war-2/rest/war2

...when the call is successful, both APIs return HTTP 201 created and a location header.

How would I go about writing a test case for this in terms of deployments?

Options I considered so far:

* single WAR deployment, mocking war2's REST API

* adding a third integration-test module to the parent project, creating both deployments and the test case there (here I'm not sure what would be the best way to create the deployments, maybe someone can provide an example)

Which approach would you recommend or is there another one that I haven't considered?

Thanks in advanced, any thoughts on this are greatly appreciated!

Cheers,

Nils

I've come up with the following solution:

* created a multi module maven project with two WARs and an additional integration test module

* the Integration test module uses ShrinkWrap to create the deployments from the existing WAR archives

* I just added the integration test module as the last module in the parent pom so the tests are executed last

* I added the maven failsafe plug-in to separate Unit and Integration tests (see http://www.oracle.com/technetwork/articles/java/integrationtesting-487452.html)

So far, this works fine for me.
