Introduction

A number of people had told me about digitalocean recently so when a new project came along I decided to try it out. Digital Ocean I had gathered was a cloud hosting platform in the vein of amazon and co. I had used AWS previously so I was interested to see how this platform would compare.

Setting up

Creating an account involved giving an email address and creating a password. After this an option was given to load credit onto the account. Paypal was accepted so I used this option to credit the account. After this I was taken to a basic screeen with a big green button labelled create. Seemed simple enough so I clicked it.

Installing RSelenium on Win 8.1

I was asked was it difficult to install and get RSelenium up and running on the windows platform.
It isn't and I made a quick screenr to show you how.

So in summary:

RSelenium: RSelenium basics

RSelenium basics

Introduction

The goal of RSelenium is to make it easy to connect to a Selenium Server/ Remote Selenium Server from within R. RSelenium provides R bindings for the Selenium Webdriver API. Selenium is a project focused on automating web browsers. RSelenium allows you to carry out unit testing and regression testing on your webapps and webpages across a range of browser/OS combinations. This allows us to integrate from within R testing and manipulation of popular projects such as shiny, sauceLabs.
This vignette is divided into six main sections:

• Connecting to a Selenium Server.
• Navigating using RSelenium.
• Accessing elements in the DOM.
• Sending events to elements.
• Injecting JavaScript.
• Frames and Windows.

Each section will be an introduction to a major idea in Selenium, and point to more detailed explanation in other vignettes.
