I tried to use it, but for my case it seems very complex, or maybe impossible, to create your module per-test due to the static map of module class -> module instance used internally by guiceberry. There is a test scope included, but I don’t see a really clean way to use that if you want to test your production guice modules.<\/p>\n","protected":false},"excerpt":{"rendered":"A JUnit4 Method rule to perform injection on your test fixture before each test case: import com.google.inject.Guice; import com.google.inject.Injector; import com.google.inject.Module; import org.junit.rules.MethodRule; import org.junit.runners.model.FrameworkMethod; import org.junit.runners.model.Statement; public class PerTestGuiceRule implements MethodRule { private final Module module; public PerTestGuiceRule(final Module … Continue reading
