TypeScript error on tests

[jonathanpauluze]

1. I'm trying to create a test following the documentation, but TypeScript shows me an error saying that I can't assign values to a read-only property
2. Steps to reproduce:
   • Create a test file (.spec.tsx)
   • Write an assertion trying to update any rdd variable

5. Code:

   
   // Component.spec.tsx
   import * as rdd from 'react-device-detect'

it('Should render correctly', () => { rdd.isSafari = true // Cannot assign to 'isSafari' because it is a read-only property

// test here... })
