Goal?

This is a built-in biolerplate project which will help you build a dockerized app for running the nightwatch tests in a parallel dockerized environment, using the concept of Selenium-grid(hub-nodes) As we know, selenium hub is a central grid for all the nodes, it accepts request and executes the tests on the available nodes.

Structure

└─── docker-compose.yml

• The page-objects and test folders use the page object concept for executing the simple nightwatch tests.

• The commands to execute the tests are defined within the package.json refering to execute the tests in both environments i.e 'Chrome' and 'Firefox'

• nightwatch.conf.js which is the default file for the runner to execute the tests, containing the necessary configurations mentioning the browser capabilities, along with details for selenium server to act as a host

• docker-compose.yml contains commands to configure Selenium grid as a hub and connect to Firefox, Chrome browser to run the tests. We have used links to link the containers with the hub container and built an image for our nightwatch project within the root of the application. You can refer to this link for configuring your docker-compose.yml file

• Lastly, the Dockerfile, which is a simple text document containing all the commands to automate building the images. This file basically contains commands for pulling the alpine image (light weight image), and install all the necessary packages to setup our nightwatchJS project.

Setup

1. Clone the repo, using command:

$ git clone https://github.com/Dikshita25/nightwatch-grid-docker-boilerplate.git

2. Navigate to the directory:

$ cd nightwatch-grid-docker-boilerplate

3. Run the docker-compose.yml file using command:

docker-compose up
