Jersey dropwizard中的单元测试视图（续）

正如在一篇文章中提到的，我正在尝试在Dropwizard中测试我的资源。这些资源可以返回json数据和视图。后者可用于freemarker模板。对于返回视图的测试路径，我扩展了的代码，还添加了一个提供程序：

@ClassRule
公共静态最终ResourceTestRule resources=ResourceTestRule.builder（）
.addResource（新的MyResource（myDAO））.addProvider（ViewMessageBodyWriter.class）.build（）；

但是，结果是出现以下冗长的错误消息：
