Stubbing Window

This is an example showing how to stub window and console calls.

The application

The application index.html has a single button that executes window.open on click. The application also prints "hello" to the console as soon as it loads.

The tests

• cypress/e2e/spec.cy.js stubs the window.open method using cy.stub(). Because the application executes window.open after the click we create the method stub after cy.visit

• cypress/e2e/spy-before-load.cy.js starts spying on console.log during cy.visit to confirm that console.log('hello') is called when the page loads.
