Mock axios requests for testing

About the fork

The original repository was not maintained as often and had pending pull requests for a while. I'll try my best to merge this back into it, if the original author wishes so.

Installing

$ npm install @anilanar/moxios --save-dev

Example

import axios from 'axios'
import moxios from '@anilanar/moxios'
import sinon from 'sinon'
import { equal } from 'assert'

describe('mocking axios requests', function () {

  describe('across entire suite', function () {

    beforeEach(function () {
      // import and pass your custom axios instance to this method
      moxios.install()
    })

    afterEach(function () {
      // import and pass your custom axios instance to this method
      moxios.uninstall()
    })

    it('specify response for a specific request', function (done) {
      let input = document.querySelector('.UserList__Filter__Input')
      let button = document.querySelector('.UserList__Filter__Button')

      input.value = 'flintstone'
      button.click()

      // Elsewhere in your code axios.get('/users/search', { params: { q: 'flintstone' } }) is called

      moxios.wait(function () {
        let request = moxios.requests.mostRecent()
        request.respondWith({
          status: 200,
          response: [
            { id: 1, firstName: 'Fred', lastName: 'Flintstone' },
            { id: 2, firstName: 'Wilma', lastName: 'Flintstone' }
          ]
        }).then(function () {
          let list = document.querySelector('.UserList__Data')
          equal(list.rows.length, 2)
          equal(list.rows[0].cells[0].innerHTML, 'Fred')
          equal(list.rows[1].cells[0].innerHTML, 'Wilma')
          done()
        })
      })
    })

    it('stub response for any matching request URL', function (done) {
      // Match against an exact URL value
      moxios.stubRequest('/say/hello', {
        status: 200,
        responseText: 'hello'
      })

      // Alternatively URL can be a RegExp
      moxios.stubRequest(/say.*/, {/* ... */})

      let onFulfilled = sinon.spy()
      axios.get('/say/hello').then(onFulfilled)

      moxios.wait(function () {
        equal(onFulfilled.getCall(0).args[0].data, 'hello')
        done()
      })
    })

  })

  it('just for a single spec', function (done) {
    moxios.withMock(function () {
      let onFulfilled = sinon.spy()
      axios.get('/users/12345').then(onFulfilled)

      moxios.wait(function () {
        let request = moxios.requests.mostRecent()
        request.respondWith({
          status: 200,
          response: {
            id: 12345, firstName: 'Fred', lastName: 'Flintstone'
          }
        }).then(function () {
          equal(onFulfilled.called, true)
          done()
        })
      })
    })
  })

})

Mocking a axios.create() instance

describe('some-thing', () => {
    let axiosInstance;
    beforeEach(() => {
      axiosInstance = axios.create();
      moxios.install(axiosInstance);
    });
    afterEach(() => {
      moxios.uninstall(axiosInstance);
    });
    it('should axios a thing', (done) => {
        moxios.stubRequest('http://www.somesite.com/awesome-url', {
          status: 200,
          responseText: reducedAsxResponse
        });
        axiosInstance.get('http://www.somesite.com/awesome-url')
            .then(res => assert(res.status === 200))
            .finally(done);
    });
});

Thanks

moxios is heavily inspired by jasmine-ajax
