This is a sample project I'm putting together that allows for teaching a Cypress course.
The basic setup steps would be the following, once you have a local copy of the repository:
npm install
If creating your own project, you would do the following:
npm init
npm install --save-dev cypress
npx cypress open
The above commands are effectively how this project was created.
To open the Cypress tool itself, you can do this:
npm run cy:open
To run tests that are stored in the Cypress repository, you can do this:
npm run cy:run
I am using a directory called e2e for all example tests so that I can set them apart from the standard ones that Cypress provides as examples.
If you want to run the tests for the simple_json area, you can do the following command:
npm run simple:json
