Question

您好我试图使用proxyquire在我的控制器中模拟一个模型。但出于某种原因，当尝试注入模拟时，原始文件被调用。

这就是控制器内部需要我的模型的方法：

var Product = require('./product.model');

这就是我试图抄袭模型的方式

  var proxyquire = require('proxyquire').noCallThru().noPreserveCache();
  var productsStub = {findAsync: sinon.stub()};
  productsStub.findAsync.resolves(mockProducts);
  var mockProducts = [{_id:'0001',title: 'title', price: 123, description: 'le description'}];
  var productController = proxyquire('./product.controller',{'./product.model':productsStub});

但是当我运行测试时出现此错误

我的问题是，如果理论上不会调用原始的products.model.js模块，我会得到这个。

Answer 1

proxyquire不会存储未列出的模块，并且它们将照常使用，因此看起来你在product.controller中有更多的依赖项，而且它们通常都是必需的。

除了为proxyquire提供完整存根之外，我找不到解决此问题的好方法。

Proxyquire调用原始文件而不是存根
