测试快递控制器在哪里访问猫鼬模型？

Question

I want to unit test my express controllers independently. But they interact with the mongoose models. So the question is how can I test them? For example -

const Model = require('./../models/mymodels');

const controller = (req, res) => {
const body = req.body;
const foo = new Model(body);
foo.save().then(foo => res.send(foo)).catch(err => res.send(error));
};

So I want to test the funtion controller independently.

Answer 1

const expect = require('chai').expect;

const Model = require('./../models/mymodels');

describe('controller test', function() {
  it('should be valid if body is correct', function(done) {
    const testBody = {myKey: "myVal"}
    const m = new Model(testBody);

    m.validate(function(err) {
      expect(err.errors).to.not.exist;
      done();
    });
  });
});

This is an example, check the chai documents for more examples
