Cypress Back#

As a software developer, I have come across the term 'Cypress Back' while working on web applications. It refers to the technique of navigating back to the previous page or state in a web application using the Cypress testing framework.

Using Cypress Back command#

The simplest way to navigate back in Cypress is by using the 'back' command. This command simulates a browser's back button click and takes the user back to the previous page or state. The code for using 'back' command in Cypress is as follows:

cy.go('back')

Using Cypress History#

Cypress also provides a History API that allows developers to manipulate the browser's history. The code for navigating back using Cypress History is as follows:

cy.window().then((win) => {
  win.history.back()
})

This code retrieves the window object and calls its 'history.back()' method to navigate back to the previous state.

Using Cypress Interception#

Another way to navigate back in Cypress is by intercepting the network traffic and returning a cached response. This technique can be useful when navigating back to a page that has already been loaded.

The code for intercepting network traffic and returning a cached response is as follows:

cy.intercept('GET', '/api/data', (req) => {
  req.reply({ fixture: 'cached-data.json' })
})

cy.visit('/my-page')
cy.get('#my-button').click()
cy.go('back')

This code intercepts the GET request to the '/api/data' endpoint and returns a cached response from the 'cached-data.json' fixture. When the user clicks on the '#my-button' element, it navigates to a new page. Finally, calling the 'back' command takes the user back to the previous state with the cached response.
