Update-alternatives: using /usr/bin/google-chrome-stable to provide /usr/bin/x-www-browser (x-www-browser) in auto mode Preparing to unpack google-chrome-stable_current_b. 129294 files and directories currently installed.) Selecting previously unselected package google-chrome-stable. I recommend the $69/mo Mac Mini on MacStadium running macOS Sierra 10.12 and the latest Safari.:~$ sudo dpkg -i google-chrome-stable_current_b In my experience, Safari (or at least safaridriver) does not behave predictably on VMs.

So while we launched 6 parallel instances of Chrome and Firefox each on a single EC2 server, we'll need a whole dedicated Mac machine for every instance of Safari on Selenium.

So what's the catch? You can only run one instance at a time. Remember those drivers we installed and moved around for Chrome and Firefox? Apple built a Selenium-compatible driver right into Safari, which means that the latest Safari runs performant and smooth on Selenium. On the one hand, the latest version of Safari ships with a native safaridriver. Selenium and Safari have a love-hate relationship. Then launch the instance with a key pair you own, and SSH into it like so:īut I have some bad news. So set up a security group with the following configuration: In my experience, a t2.micro EC2 instance on Ubuntu 16.04 works perfectly!īut heads up! Your Selenium Hub must be open on port 4444 (and it's generally a good idea to leave a port open for SSH). and one Node on MacStadium (for Safari).one Node on EC2 (for Chrome and Firefox).This tutorial walks through setting up a Selenium Grid, specifically: Xvfb allows Selenium to run headless (without a screen), which is necessary because EC2 instances don't have visual displays.A Selenium Grid Node is responsible for actually running the processes (and does most of the heavy lifting).A Selenium Grid Hub is sort of like a load balancer, it takes requests from remote clients and delegates them to available Nodes.Since functional tests often run pretty slow, and most websites need lots of them, running processes in parallel is critical. Selenium Grid is a way to parallelize Selenium processing.The most common (and benevolent) use case is running automated tests across browsers. Selenium is a framework for automating browser interaction.Before diving in, it's worth defining the relevant terms:
