Sinon存根。resolves()未按要求运行

sinon unit-testing node.js

下面是我正在编写测试的函数:

ensureUserDoesNotExist(request, response, next) {
  this.User.findOne({ where: { email: request.body.email }})
    .then(user => {
      if (user) {
        response.sendStatus(403);
      } else {
        next();
      }
    });
  }

以下是我无法通过的测试:

it('should return a 403 if a matching user is found', () => {
  mockRequest.body.email = 'test@email.com';
  userController.User.findOne.resolves(true); // This is a previously created sinon stub
  userController.ensureUserDoesNotExist(mockRequest, mockResponse, mockNext);
  assert(mockResponse.sendStatus.calledWith(403));
});

它失败了,只是声称没有调用存根(不管它值多少钱)。

我强烈怀疑这与承诺有关,或与希农的互动有关,但我在试图弄清楚到底是什么方面完全没有头脑。代码按预期工作(或者在我上次查看它之前,它就按预期工作了)。有人能帮我吗?

在结束请求之前评估您的断言你需要回报承诺

ensureUserDoesNotExist(request, response, next) {
  return this.User.findOne({ where: { email: request.body.email }})
    .then(user => {
      if (user) {
        response.sendStatus(403);
      } else {
        next();
      }
    });
  }

并在中断言 then 条款

it('should return a 403 if a matching user is found', () => {
  mockRequest.body.email = 'test@email.com';
  userController.User.findOne.resolves(true); // This is a previously created sinon stub
  userController.ensureUserDoesNotExist(mockRequest, mockResponse, mockNext).then(() => {
     assert(mockResponse.sendStatus.calledWith(403));
  });
});

测试还必须向Mocha返回一个承诺,以指示异步测试。您可以使用 then 电话:

it('should return a 403 if a matching user is found', () => {
  mockRequest.body.email = 'test@email.com';
  userController.User.findOne.resolves(true); // This is a previously created sinon stub
  return userController.ensureUserDoesNotExist(mockRequest, mockResponse, mockNext).then(() => {
      assert(mockResponse.sendStatus.calledWith(403));
  });
});
