### Question:
DecisionDiscovery { public Set<Class<?>> discover(String packagePrefix) { Reflections reflections = new Reflections(new ConfigurationBuilder() .setUrls(ClasspathHelper.forPackage(packagePrefix)) .filterInputsBy(new FilterBuilder().includePackage(packagePrefix)) ); return reflections.getTypesAnnotatedWith(DRGElement.class); }  Set<Class<?>> discover(String packagePrefix);  }### Answer:
@Test public void testDiscovery() { Set<Class<?>> decisions = decisionDiscovery.discover("com.gs"); assertEquals(1, decisions.size()); Class<?> first = decisions.iterator().next(); assertEquals("com.gs.dmn.runtime.discovery.NopDecision", first.getName()); }
