通过网络浏览器运行测试工作正常，但使用 grunt 会给我错误。我很难理解我在这里做错了什么。grunt tests失败了

作为 grunt 过程中的另一个步骤，您需要运行 Node 服务器。有一个专门运行 Express 服务器的繁重任务，我建议从那里开始。下面是 grunt 配置的样子：

grunt.initConfig({
    // ...
    express: {  // this is the new task...
      dev: {
        options: {
          script: 'path/to/main.js'
        }
      }
    },
    connect: {
      server: {
        options: {
          port: 3000,  // I changed this so it doesn't conflict with your express app
          base: '.'
        }
      }
    },
    qunit: {
      all: {
        options: {
          urls: [
            'http://localhost:3000/tests/tests.html'  // changed this as well
          ]
        }
      }
    }
});

然后，您将希望在“测试”运行时运行所有三个任务。您可以像这样创建别名：

grunt.registerTask('tests', ['jsonlint', 'jshint', 'express', 'connect', 'qunit']);
