Question

我正在尝试通过Heroku管道执行以下app.json：

的测试

{
  "environments": {
    "test": {
      "addons": [
        {
          "plan": "mongolab:sandbox"
        }
      ],
      "scripts": {
        "test": "yarn test && ((nohup yarn test:start:api &) && sleep 10 && yarn test:integration)"
      }
    }
  }
}

在我的Linux机器上，该命令可以正常工作，但在Heroku上我无法访问API服务：

如何确定连接到API服务本身的URI（nohup yarn test:start:api &）？

API是使用express-restify-mongoose构建的，因为似乎没有开箱即用的测试，例如注入hapijs（https://hapijs.com/api#-await-serverinjectoptions）

如何在Heroku上运行测试？

Answer 1

您的测试正在尝试连接到127.0.0.1:8080，但您的Web应用程序几乎肯定会在其他地方运行。 Heroku provides the PORT environment variable告诉你的后端代码应该使用哪个端口。

尝试更新您的测试以连接到该变量而不是8080。
