Dropwizard 1.0.2 Bundle for Feature Toggles using https://www.togglz.org/

Todo

• persist toggles StateRepository can be implemented via AbstractFeatureToggleBundle#getStateRepository
• auth (basic)

Example

Create enum implementing Feature interface.

public enum Feature implements org.togglz.core.Feature {

    FEATURE_ONE;

    public boolean isActive() {
        return FeatureContext.getFeatureManager().isActive(this);
    }
}

Define default config with reference to Feature enum.

togglz:
  spec: "edu.thinktank.togglz.example.Feature"
  alwaysOverrideFeatureStates: true
  features:
    FEATURE_ONE: true

Start using Enum.

if(Feature.FEATURE_ONE.isActive()) {
    ...
}

Enable/Disable feature at runtime via admin console http://localhost:8080/admin/togglz/

Testing

FeatureToggleTestSupport class contains convenience methods for testing.

public class ResourceTest {

    @ClassRule
    public static final ResourceTestRule resources = ResourceTestRule.builder()
            .addResource(new Resource())
            .build();

    @Before
    public void setupFeatures() {
        FeatureToggleTestSupport.initAllFeatures(Feature.class, false);
    }

    @Test
    public void testFeatureOne() throws Exception {
        FeatureToggleTestSupport.enable(Feature.FEATURE_ONE);
        String response = resources.client().target("/").request().get().readEntity(String.class);
        assertThat(response).isEqualTo("feature one enabled, feature two disabled");
    }
}
