It's easy to verify if your test project is missing some soft dependencies. In your dev environment, in Run Configuration of your test -> Plugins Tab:
1. select plug-ins selected below only
2. Deselect All
3. In filter field, type your test plug-in ID to find it in the list of plugins.
4. Select this plug-in.
5. Clean up the filter.
6. Press Add Required Plug-ins
Here we go. Now you can run the test and see if it fails since now your test environment includes the same set of plugins which you have in your maven build.

Hey Xavier,

This is a shot in the dark, but you might verify that the plugins providing the model provider are listed as dependencies for the test plugin.  My experience has shown that the test environment only includes hard dependencies, so if you're relying on something that has a soft link (e.g. anything contributed through an extension point), you need to make sure the plugin making the contribution (e.g. implementing the extension point) is included in the dependencies list for your test plugin.  It probably works fine in your dev env because Eclipse is using the entire set of plugins available (i.e. target platform + workspace plugins).

Good luck.

Hello,

I just got a NPE with tests running from Maven (they run fine from PDE, though):  'org.eclipse.jst.j2ee.model.ModelProviderManager.ModelProviderManager.getModelProvider(project)returns 'null' in the WizardPages that I'm trying to test.

For the moment, I'll skip those tests on maven to avoid build failures on Jenkins, but if anyone has a clue what I should do to get them pass on maven/Jenkins (i.e., initialise the ModelProviderManager ?), please let me know ;-)

Thanks !
Best regards,
/Xavier
