有没有一种方法可以在使用Cloud Translation Java库时轻松编写集成测试？

Question

我正在编写一项将调用Google Cloud Translation服务的服务。

我正在使用Java库com.google.cloud:google-cloud-translate:4.0.0

我想用以下设置编写一些集成测试：

• wiremock服务器将充当翻译api
• 我的服务将 配置TranslationServiceClient以用作我的自定义端点 Wiremock

原因是，针对真实api进行全套集成测试会很快变得昂贵。

我似乎无法覆盖HostNameVerifier的实现，因此我的所有测试均失败，但出现以下异常：
