Protractor backend mock plugin

Protractor plugin used to mock backend calls.

Usage

1. Add NPM dependency to your package.json:

   npm install --save-dev protractor-backend-mock-plugin

2. Add & Configure Protractor plugin:

   // protractor.conf.js
   exports.config = {
       plugins: [
           {
               package: 'protractor-backend-mock-plugin',
               // config
               backend: [8080, 'localhost'],
               fake: [9999, 'localhost']
           }
       ]
   }

3. Use Nock to mock results from fake server:

   npm install --save-dev nock

   import * as nock from 'nock';
   beforeEach(() => {
     nock('http://localhost:9999').get(`/user/me`).reply(200, {id: 42, name: 'John Doe'})
   });

How it works?

An Express.js server is started locally, to intercept webapp calls. In order to intercept and mock calls (using nock), request must be emitted inside NodeJS application. So all request are redirected to another URL, defined by fake section.
