This tool will use a globally installed version of Backstop to run Visual Regression Testing on your machine using a local url and comparing to a live url.

To properly run this tool you will need to ensure you are on Node Version 16 or higher and first install Backstop JS globally. npm install -g backstopjs

4. Run backstop init to initialze backstop on this project
5. Return to the root of your project.

7. Run composer backstop-setup from the root of your project and input your local and live urls when prompted
