Question

我已经使用Twilio的API设置了一个工作函数。当我通过UI输入参数时，该功能起作用，但是当我在Mocha中运行测试时，它无法声明该函数未定义。我还在Mocha中进行了另一项测试，该测试在此测试之前运行并且第一次测试通过。

twilioClient.js：

var config = require('./config');
var client = require('twilio')(config.accountSid, config.authToken);

sendSms = function(to, message) {
  client.messages.create({
    body: message,
    to: to,
    from: config.sendingNumber
    // mediaUrl: 'http://www.yourserver.com/someimage.png'
  }, function(err, data) {
    if (err) {
      console.error('Could not notify administrator');
      console.error(err);
      return 'Could not notify administrator';
    } else {
      console.log('Administrator notified');
      return 'Administrator notified';
    }
  });
};

module.exports.sendSms = sendSms;

我的indexSpec.js文件：

var chai= require('chai');
var expect = require('chai').expect;
var twilioNotifications = require('./Send Text/js/twilioNotifications');
var cfg = require('./Send Text/js/config.js');
var twilio = require('twilio');
var tClient = require('./Send Text/js/twilioClient.js');

describe('TwilioVars', function() {
    it('returns true if variables are not null nor undefined', function() {
        var tVars = cfg.twilioVars(cfg.reqConfig);

        expect(tVars).to.equal(true);
    })
})

describe('MsgSent', function() {
    it('confirms if message can be sent', function() {
        var receiver = <my number>;
        var message = 'My message';
        var sentMsg = tClient.sendSms(receiver, message);   

        expect(sentMsg).to.equal('Administrator notified');
    })
})

我的config.js文件：

var cfg = {};
cfg.accountSid = <some string>;
cfg.authToken = <some string>;
cfg.sendingNumber = <some string>;

var requiredConfig = [cfg.accountSid, cfg.authToken, cfg.sendingNumber];

// For testing:
cfg.reqConfig = requiredConfig;
cfg.twilioVars = function(arr) {
    if (arr[0] && arr[1] && arr[2]) {
        return true;
    }
    return false;
};
// End testing

var isConfigured = requiredConfig.every(function(configValue) {
  return configValue || false;
});

if (!isConfigured) {
  var errorMessage =
    'TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN, and TWILIO_NUMBER must be set.';

  throw new Error(errorMessage);
}

// Export configuration object
module.exports = cfg;

任何关于函数运行原因以及测试失败原因的见解都将非常感激。

P.S。错误如下：

 1) MsgSent confirms if message can be sent:

您的sendSms函数可能是异步的，您需要等待它完成才能测试它的输出。考虑添加一个回调函数，您可以在client.messages.create()进行回调时调用该函数，并使用done。或者考虑从sendSms返回承诺。

例如：

twilioClient.js：

...
sendSms = function(to, message, cb) {
  client.messages.create({
    ...
  }, function(err, data) {
    ...
    cb(err, data);
  });
};

indexSpec.js：

...
describe('MsgSent', function() {
  it('confirms if message can be sent', function(done) {
    ...
    var sentMsg = tClient.sendSms(receiver, message, function(err, data) {
      expect(data.sentMsg).to.equal('Administrator notified');
      done();
    });
  });
});

节点功能有效，但在通过Mocha运行时未定义
