Nemo Objects

Easily implement and use the Page Object pattern in your nemo based tests, by using a simple api, mostly inspired by the ember-cli-page-object ember addon, widely used in the ember ecosystem for functional and integration testing.

Installation

  npm install --save nemo-objects

Usage

Configuring the nemo plugin

In your nemo configuration, with an absolute path specify where your page objects are.

  {
    "plugins": {
      "nemo-objects": {
        "module": "nemo-objects",
        "arguments": [
          {
            "pagesLocation": "/path/to/page-objects"
          }
        ]
      }
    }   
  }

Creating a page object

At the specified location, for any given file found a page object will be created at the nemo.objects namespace. For example, if a file named countryCenter.js is found, then a page object is created as nemo.object.countryCenter.

At the countryCenter.js file, a page-object can be declared as follows:

  'use strict';

  module.exports = function countryCenterPage(pageObject, nemo) {
    const { visitable, collection, text } = pageObject;

    return {
      visit: visitable(`${nemo.data.url}/country-center`),
      countries: collection({
        scope: '.country-list',
        itemScope: 'ul li',
        item: {
          countryName: text('span')
        }
      })
    };
  };

Which later can be used at your functional tests as:

  // all the setup code for your nemo environment
  // The `nemo` variable is made available here

  describe('At the country center page', () => {
    it('All user countries are shown', async () => {
      const { countryCenter } = nemo.objects;

      await countryCenter.visit();
      const countries = await countryCenter.countries();
      
      expect(countries.length).to.be.equal(4, 'the number of countries matches the user settings');
    });
  });

API

Plugin configuration

• options
  • pagesLocation - An absolute path indicating where you page objects are

Page objects

Each module located at the specified location should export a function, which receives the following arguments:

• pageObject - Holds the pageObject helper functions to be used along with your page objects
• nemo - The nemo instance

Each module is expected to return an object describing the page object.
