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

my advice is to return Cypress chainable instance to do 
```js
function returnSomething() {
  return cy.log('howdy').then(() => {
    return 'yo'
  })
}
it('returns values', () => {
  returnSomething().then(cy.log)
})
```
Also about return values - inside `returnSomething` you could do
```js
function returnSomething() {
  cy.log('howdy')
  return cy.wrap('yo')
}
```
