### Question:
StandardJavaGenerator implements Generator { @Override public RenderStack getRenderStack() { return generator.getRenderStack(); } StandardJavaGenerator(); @Override DependencyManager getDependencyMgr(); @Override RenderStack getRenderStack(); @Override Stream<Meta<A, B>> metaOn(A from,
            Class<B> to); @Override Optional<Meta<A, B>> transform(
            Transform<A, B> transform, A model,
            TransformFactory factory);  }### Answer:
@Test void getRenderStack() { assertNotNull(INSTANCE.getRenderStack()); }
