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

And if you would try that on failure to just create a screenshot. This is an example that uses debugger but maybe you can also do a cy.screenshot.
```js
Cypress.on('fail', (error, runnable) => {
  debugger

  // we now have access to the err instance
  // and the mocha runnable this failed on

  throw error // throw error to have test still fail
})
```
