sinon-express-mock

Simple request and response mock objects to pass into Express routes when testing using Sinon.

The mock objects attach Sinon spys to request methods. See src/index.js for a full list of stubbed out methods.

Install

npm install --save-dev sinon-express-mock sinon

Depends on:

• Node v4+ (or Object.assign support needed)
• Sinon

Usage

Contents of src/foo.js:

export default (req, res) => {
  res.json({ foo: req.body.foo })
}

Contents of test/foo-test.js:

import route from '../src/foo'
import chai, { expect } from 'chai'
import sinonChai from 'sinon-chai'
import { mockReq, mockRes } from 'sinon-express-mock'

chai.use(sinonChai);

describe('my route', () => {
  it('should foo the bar', () => {
    const request = {
      body: {
        foo: 'bar',
      },
    }
    const req = mockReq(request)
    const res = mockRes()

    route(req, res)

    expect(res.json).to.be.calledWith({ foo: request.body.foo })
  })
})
