Ve Interactive recruitment JavaScript test

The goal of this test is to capture data present on a page in order to report them to an API.

In order to do that, the test you are about to start is split in 2 different parts:

1. Programming
2. Unit testing

1. Programming

You have an HTML page (index.html) which contains a form and some information about what the customer is buying. The goal is to capture all of that information and to send it using the DataReporter class. In this test the DataReporter class prints all the captured data in the console.

You will find all information related to the DataReporter class in available code.

In order for you to be able to capture and identify all those pieces of data, you have been given a 'mappings' array (mappings.js) that contains information on how to capture them.

e.g. Let's take the mapping 1:

{
    id: 1,
    selector: '#email',
    attribute: 'value',
    event: 'onChange',
    isEmail: true,
    isPhoneNumber: false
}

• id: The id is the identifier of the data you will be capturing. It will help you not to send the same data over and over again if it didn't chage + it will allow the Back-end to identify what data you are sending.
• selector: A css selector helping you getting the DOM element you need data from.
• attribute: The attributes relate to the type of data you will have to get from your DOM element.
  • text: relate to the innerText of your element - e.g. your element: <div>example</div>, you would get: 'example'.
  • value: relate to the value of your element - e.g. your element: <input type="text" value="my value" />, you would get: 'my value'.
  • radio: relate to the value of the selected radio button.
  • checkbox: if your checkbox is checked, it should return 'Checked', otherwise it should return 'Unchecked'.
• event: Specifies when you will be capturing the data you need
  • onLoad: When the page is loaded
  • onChange: When the DOM element will have changed
• isEmail: If this value is true, the captured value should only get stored/send when it is a valid email.
• isPhoneNumber: If this value is true, the captured value should only get stored/send when it is a valid UK phone number.

2. Unit testing

You are to unit test the JavaScript code you have written.

You can use Jasmine framework to do that. Example of unit tests for the DataReporter can be found in Test folder. You need node.js installed to perform tests. You can use npm install command to install required packages that will run tests. The command should be executed in the command prompt in the directory with the package.json. After that you have to add created files in karma.conf.js and run karma start command in your project folder. Once you do that follow the instruction seen on terminal.
