Weld (CDI): where do I put my test-only beans.xml that configures <alternatives>?

Question

My webapp has a non-empty production beans.xml under src/main/resources/META-INF. Now, for my tests, I need to swap out 1 bean with an alternative.

Where do I put this test beans.xml which contains just this and nothing more?

<?xml version="1.0" encoding="UTF-8"?>
<beans ...>
  <alternatives>
    <class>...MyTestReplacement</class>
  </alternatives>
</beans>

I tried under src/test/resources/META-INF but that is ignored. I am using arquillian and my test classpath is added to the ShrinkWrap.

Even though it's already accepted, ill post you the solution I found. I had the same problem, and using @Specializes was no option for me, because I had many mocks with several methods, thus create for each one a class was a bit overkill....

So in my test I have a ResourceMock:

@Produces
@Alternative
public IResource createResource() {
    Resource resource = mock(Resource.class);
    when(resource.getLocalized(anyString())).then(AdditionalAnswers.returnsFirstArg());
    return resource;
}

With the following ShrinkWrap I was able to load those @Alternative bean only during the test: (no beans.xml in the test dir needed!)

return ShrinkWrap
            .create(JavaArchive.class)
            .addPackages(true, "some.package.with.classes")
            .addAsManifestResource(
                    new StringAsset(
                            "<alternatives><class>my.testclass.with.alternatives</class></alternatives>"),
                    "beans.xml");

And that's it.

Don't use @Alternative, but use @Specializes. Just put the @Specializes bean only in your test classpath and it will automatically replace the real bean. No need to mess around with beans.xml.
