Other than just maybe some reuseable code. Everything else looks like and the code coverage on the backend is starting to look great 🔥 🚀 🎸

Something you could do to reuse code would be to put the userEmail, uuid & spy all into a beforeAll

Ex:

let uuid;
let userEmail;
let spy;
BeforeAll(() => {
   // 
  // 
  //
}
