在node.js中编写一个简单的自动化测试,但同步调用有问题

我正在尝试编写一个自动化脚本来测试我的一些api调用,这是一个简单的例子:

async.series([
    function(callback){
       func.clean_database()
       callback(null);     
    },
    function(callback){
       func.register_and_auth(users[0])
       callback(null);   
    }
],
function(err, results){
    console.log('done');
});

清理数据库看起来很简单:

clean_database: function () { 
    var Projects = mongoose.model("Projects", new mongoose.Schema({}));
    Projects.collection.remove(function (err, results) { console.log("Emptied: Projects"); });
    return true;
},

问题是register_and_auth(users [0])在清理数据库完成之前运行..因此告诉我用户已经注册。我的印象是async.series将串行运行,即一个接一个。

如何才能使回调(null)与我在第一步中运行的函数的完成相关联?

谢谢!

:::: UPDATE ::::

如果有人关心,我必须扩展这个并调用更多方法来模仿用户流程,这是最终的样子......如果有人想改进这一点,请做

async.series([    
  func.clean_database, function(one_callback){
    func.register_and_auth(users[0], function(callback) {
      console.log('-- Starting Create and Upload');
      func.auth_and_create_project_and_upload(users[0], data, function(callback) { 
        console.log('-- Starting Annotations');
        func.auth_open_project_add_annotations_to_all_pages(users[0], annotation, function(callback) { 
          console.log('-- Done with User 0.');
          one_callback();
        });
      });
    });
  },
  function(two_callback) {
    func.register_and_auth(users[1], function(callback) {
      console.log('-- Starting Create and Upload');
      func.auth_and_create_project_and_upload(users[1], data, function(callback) { 
        console.log('-- Starting Annotations');
        func.auth_open_project_add_annotations_to_all_pages(users[1], annotation, function(callback) { 
            console.log('-- Done with User 1.');
            two_callback();
          });
        });
      });
    },
  ],
  function(err, results){
  console.log('Load test complete for two users.');   
});

您需要传递回调并在任务完成后调用它们

async.series([
    func.clean_database,
    function(callback){
       func.register_and_auth(users[0], callback);
    }
],
function(err, results){
    console.log('done');
});

clean_database: function (callback) { 
    var Projects = mongoose.model("Projects", new mongoose.Schema({}));
    Projects.collection.remove(function (err, results) { 
      console.log("Emptied: Projects"); 
      callback(err, results);
    });
    return true;
},
