  -### `toHaveProperty(keyPath, value)`
  +### `.toHaveProperty(keyPath, value)`
  Use `.toHaveProperty` to check if property at provided reference `keyPath` exists for an object.
  For checking deeply nested properties in an object use [dot notation](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Operators/Property_accessors) for deep references.
