With Cypress, you can easily create tests for your modern web applications, debug them visually, and automatically run them in your continuous integration builds.

I found a trick, havent perfected it yet but its based on the metaprogramming page of Gleb. 

I have now in my e2e.js file the following code.
```js
import './commands'

var isFailed = false;
var failedTitle;

Cypress.on('fail', (error, runnable) => {
  
  failedTitle = runnable.fullTitle();
  isFailed = true

  throw error
})

afterEach(function() {
  if(isFailed){
    cy.screenshot(`The failed test is ${failedTitle}`,{capture: "fullPage"})
    isFailed = false
  }
})
```

This gives you 2 screenshots one the default when it failed.
And the second a screenshot that makes a fullpage with the failed test title.

Hope this will help you
