As mentioned in a related post I am trying to test my resources in Dropwizard. The resources can both return json data and views. The latter work with freemarker templates. For testing paths which return views I extended the code of the dropwizard manual to also add a provider:

@ClassRule
public static final ResourceTestRule resources = ResourceTestRule.builder()
        .addResource(new MyResource(myDAO)).addProvider(ViewMessageBodyWriter.class).build();

The result however is the following lengthy error message:

WARN  [2015-04-14 12:00:33,471] org.glassfish.jersey.internal.Errors: The following warnings have been detected: WARNING: HK2 service reification failed for [io.dropwizard.views.ViewMessageBodyWriter] with an exception:

Looks like HK2 cannot instantiate ViewMessageBodyWriter by only giving the class name; which means you need to create it yourself. There is an example in dropwizard tests.

@ClassRule
public static final ResourceTestRule resources = ResourceTestRule.builder()
        .addResource(new MyResource(myDAO)).addProvider(new ViewMessageBodyWriter(new MetricRegistry(), ImmutableList.of(new FreemarkerViewRenderer()))).build();
