【问题描述】：

我正在尝试通过参考this 指南在本地开发服务器上运行 Google pubsub java 示例 - appengine 推送。

$ gcloud config set project <provided-my-application-id>
$ mvn gcloud:run

Maven 构建成功，但测试运行失败。下面是执行。如何解决？

更新 - 测试运行失败观察： 我的观察是， 对于 testTopPage() - 第 72 行通过，响应为 200。但在第 84 行失败，因为内容没有我的项目 _id。

对于 testSendMessage() - 在第 133 行失败，出现 404 错误，url = getAppBaseURL() + "send_message";因为没有这样的资源。

同样，testPushHandlerIsProtected()- 在第 110 行失败并出现 404 错误，因为没有这样的资源。

注意：我的项目在 appengine 中只有 hello world 应用程序，但这些测试方法正在寻找 appengine 中不存在的资源。我错过了什么？

【问题讨论】：

  • 您必须在 appengine 上部署示例应用程序才能进行测试（请参阅我的答案的编辑）。

标签： java google-app-engine google-cloud-pubsub


【解决方案1】：

查看第 31 行 in the test。它使用称为“TEST_PROJECT_ID”的不同环境变量（参见第 24 行）。它应该像设置正确的环境变量一样简单。您还可以在单​​元测试中为 URL 添加调试输出，以便了解使用的主机名。

Edit1：你的意思是，你在 appengine 中只有一个 hello world 应用程序？ 'send_message' 资源和 init_servlet（它返回第 84 行断言的项目 ID）在示例的 web.xml 中定义。您必须先部署此应用程序，然后再针对它运行测试（或找到该应用程序的一个已在运行的实例）。如果由于测试失败而无法部署应用程序，则可以通过将 -DskipTests 参数添加到 maven 命令来跳过安全测试。这也解释了in the readme of the project。

【讨论】：

  • 环境变量按预期提供。我的观察结果是，对于 testTopPage() - 第 72 行，响应代码为 200，符合预期。但在第 84 行失败，因为内容没有我的项目 _id。对于 testSendMessage() - 在第 133 行失败，出现 404 错误，url = getAppBaseURL() + "send_message";因为没有这样的资源。对于 testPushHandlerIsProtected() - 在第 110 行失败并出现 404 错误，因为没有这样的资源。这些测试方法正在寻找 appengine 中不存在的资源。我错过了什么？如何完成这项工作？
  • 用测试运行失败观察更新了问题。
  • 是的。我在部署项目时遇到了一些困难。发布了一个单独的问题来解决这里部署时遇到的错误 - stackoverflow.com/questions/39234400/…
