Setting up testing with Selenium

This is not a MDriven specific instruction, it's a page with short instructions and links to other pages to make it easy to know one way to follow to set up testing towards your system.

Selenium does testing of web sites, so it's targeting a TurnKey application. These instruction and testing has all been done on Windows 11.

Selenium is a very widely used framework for running scripted web tests. You can use it both for application testing and for load testing. Load testing though will be for a small number of clients, because it takes a lot of CPU and memory on the test server to run parallel web browsers.

The easiest way we recommend is using the Selenium IDE plug-in for your browser, for example Chrome. With the IDE you can create, edit and run a script without any setup on your local development machine.

Most of what you run you run from the Selenium command line runner, readhere

Here is a quick summary;

Install the Selenium command line runner Command Line Runner

• The command line runner uses node.js.
  • Install the node.js from https://nodejs.org/en/download/ using the windows installer.
    
• Once node.js is installed, run npm install -g selenium-side-runner

When you have a script that does what you want it to do, as simple and complex as that need to be, you install a Selenium Grid execution environment to run many copies of your test either after each other, or probably more important, in parallel to ensure good overall performance.

Installing a Selenium Grid is surprisingly simple, and we recommend this configuration (there are any number of different ways)

• Install WSL2 on Windows (add feature to Windows)
  • Make sure that your machine has vCPU turned on in BIOS.
• Install Docker Desktop
