Performance Testing Using Cypress.io

Supporting materials for my session on Automation Guild 2021 where I will share how to extend Cypress to test for web performance.

Pre-requisites

• Node and NPM [LTS version]
• Visual Studio Code or any text editor of your choice

Getting Started

To get started on the hands-on material, simply clone this repository, cd to the project root and then install the project dependencies by typing in npm i on your chosen terminal.

Running The Tests

To open the Cypress Test Runner, simply type npx cypress open and select the file that you want to run.

Alternatively, to run it headlessly on Chrome, type npx cypress run --browser chrome --headless
