如何用实际流量单元测试流星方法:mocha

Question

我正在为流星写一个噩梦写单元测试.有太多旧的,过时的文章和太少的清晰,相关的文档,以便我能够找出实际需要做的事情来实现这一点.

我遇到了问题之后的问题,并且真的希望有人可以告诉我他们如何为我的一种方法编写测试,这样我就可以看到他们做了什么,并为我的其余方法进行逆向工程.

这是我想为以下方法编写测试的方法:

Meteor.methods({
  'client.new':( clientDetails ) => {
    check( clientDetails, {
      name: String,
      numberTeamMembers: String
    });

    clientDetails.teamMembers = [];

    if(!Meteor.userId() || !Roles.userIsInRole(Meteor.userId(), 'administrator')) {
      throw new Meteor.Error('500', 'You are not authorised to do this.');
    }

    if(Clients.findOne({ name: clientDetails.name})) {
      throw new Meteor.Error('500', 'This client name already exists!');
    };

    return Clients.insert(clientDetails);
  },
});

到目前为止,我有以下内容:

import { Meteor } from 'meteor/meteor';
import { expect, be } from 'meteor/practicalmeteor:chai';
import { describe, it, before } from 'meteor/practicalmeteor:mocha';
import { resetDatabase } from 'meteor/xolvio:cleaner';
import { Random } from 'meteor/random';

import { Clients } from '/imports/api/clients/clients.js';

import '/imports/api/clients/server/methods.js';

describe('Client Methods in API', function() {
  before(function() {
    resetDatabase();
  });

  it('can create a Client', function(){
    let clientName = "Microsoft",
        numberTeamMembers = "5",
        data = {
          name: clientName,
          numberTeamMembers: numberTeamMembers
        };

    let userId = Accounts.createUser({username: "admin", email: "admin@admin.com", password: "password"});
    Meteor.users.update({ _id: userId }, { $set: { roles: [ 'administrator' ] }});

    let method = Meteor.server.method_handlers['client.new'];

    method.apply(userId, [data]);


    let client = Clients.findOne();

    expect(Clients.find().count()).to.equal(1);
    expect(client.name).to.equal(clientName);
    expect(client.numberTeamMembers).to.equal(numberTeamMembers);
  });
});

上面测试抛出的错误首先告诉我Meteor.userId can only be invoked in method calls. Use this.userId in publish functions.哪个是无关紧要的,因为这是我正在测试的方法.其次,该方法抛出错误('您无权执行此操作'),因此它无法识别Meteor.userId()或用户处于"管理员"角色的事实.

如果有人能告诉我他们将如何测试这种方法,我真的很感激!

谢谢

我认为你需要研究这个Meteor.user()方法，试试这个：

import { Meteor } from 'meteor/meteor';
import { resetDatabase } from 'meteor/xolvio:cleaner';
import { sinon } from 'meteor/practicalmeteor:sinon';

describe('...', () => {
  let currentUser;

  beforeEach(() => {
    resetDatabase();
    Factory.define('user', Meteor.users, {
      profile: {
        // ...
      },
    });
    currentUser = Factory.create('user');
    sinon.stub(Meteor, 'user');
    Meteor.user.returns(currentUser);
  });

  afterEach(() => {
    Meteor.user.restore();
    resetDatabase();
  });

  it('...', () => {
    // ...
  });
});

您需要添加这些包：dburles:factory, xolvio:cleaner,practicalmeteor:sinon
