Sainsbury’s Software Engineering Test

This task is intended to test your ability to consume a webpage, process some data and present it. While there is no specific time limit, we would not expect you to spend any longer than 2 hours completing this. We are looking for concise, testable, clean, well commented code and that you have chosen the right tools for the right job. We will also be looking at your app structure as a whole. Requirements Using best practice coding methods, build a console application that scrapes the Sainsbury’s grocery site - Ripe Fruits page and returns a JSON array of all the products on the page. Example of the table below:

You need to follow each link and get the size (in kb) of the linked HTML (no assets) and the description to display in the JSON Each element in the JSON results array should contain ‘title’, ‘unit_price’, ‘size’ and ‘description’ keys corresponding to items in the table. Additionally, there should be a total field which is a sum of all unit prices on the page.

The link to use is: http://www.sainsburys.co.uk/webapp/wcs/stores/servlet/CategoryDisplay?listView=tr ue&orderBy=FAVOURITES_FIRST&parent_category_rn=12518&top_category=125 18&langId=44&beginIndex=0&pageSize=20&catalogId=10137&searchTerm=&categ oryId=185749&listId=&storeId=10151&promotionId=#langId=44&storeId=10151&cat alogId=10137&categoryId=185749&parent_category_rn=12518&top_category=1251 8&pageSize=20&orderBy=FAVOURITES_FIRST&searchTerm=&beginIndex=0&hide Filters=true Example JSON:

{ "results":[ { "title":"Sainsbury's Avocado, Ripe "size": "90.6kb", "unit_price": 1.80, "description": "Great to eat now - avocado counts as 1 of your 5..." }, { "title":"Sainsbury's Avocado, Ripe "size": "87kb", "unit_price": 2.00, "description": "Great to eat now - avocado counts as 1 of your 5..." } ], "total": 3.80 } & Ready x2", refrigerate at home 1 of 5 a day 1 & Ready x4", refrigerate at home 1 of 5 a day 1 Your code should:

• Include unit and / or behavioural tests.
• Include a README.md file in the root describing how to run the app, how to run tests and any dependencies needed from the system
• Work on whichever of the following is relevant to the role you are applying for: PHP5.4+, Python 2.7+, Golang 1.4+, Java 1.7+ You may use a dependency management system (e.g. composer, pip) and as many dependencies as you like. Please provide a link to a public VCS (github, etc)
