sinon stubs在nodejs測試中不起作用

Question

我正在爲Invoicer模塊編寫測試。

我有兩個問題與我的測試。第一個原因是電子郵件仍然被髮送，儘管它已經存在emailjs模塊（第一次測試），第二個問題是我的第二次測試超時後2secs。

我不明白爲什麼？

任何人都可以幫我解決這個問題嗎？

Invoicer

'use strict'; 

var fs = require('fs'); 
var _ = require('underscore'); 
var request = require("request"); 
var email = require("emailjs"); 


exports.Invoicer = function (url, context) { 

    // set-up our transporter object with credentials 
    var transporter = email.server.connect({ 
     user: 'Pinoquio', 
     password: 'sdlfkjlj', 
     host: "pinoquio@gmail.com", 
     port: 444, 
     tls: true 
    }); 

    // read html file for email 
    fs.readFile('./email.html', function(error, data){ 

     if (error) { 
      context.done(new Error("There was an error reading the file ---> %s", error.message)); 
     } 

     data = data.toString(); 

     var template = _.template(data); 

     // request data from url 
     request(url, function (error, response, body) { 
      if(error) { 
       context.done(new Error("There was an error with request --> %s", error.message)); 
      } 

      if (!error && response.statusCode == 200) { 

       if(typeof body === "string") { 
        var _body = JSON.parse(body); 
       } 

       var populated_html = template(_body); 

       var mailOptions = { 
        text: populated_html, 
        from: 'hick <hick@beta.hick.com>', // sender address 
        to: '<mario@hick.com>', // recipient 
        subject: 'Invoice' 
       } 

       transporter.send(mailOptions, function(error, message){ 
        if(error){ 
         context.done(new Error("There was an error sending the email: %s", error.message)); 
        }else{ 
         context.done(); 
        } 
       }); 
      } 
     }); 
    }); 
};

Answer 1

我已經設法解決第二個問題首先通過將return的context.done(new Error....)

fs.readFile後（」 ./ email.html '，功能（錯誤，數據）{

if (error) { 
    context.done(new Error("There was an error reading the file ---> %s", error.message)); 
    return; 
} 

，並通過傳遞有效的文件名在我的測試，而不是隻是一個隨機字符串：

readFileStub.withArgs("./email.html").callsArgWith(1, new Error("Error reading file"), null); 
}); 

after(function() { 
    fs.readFile.restore(); 
});
