DO split tests using the frameworks' capabilities

RegistrationForm.spec.ts

describe('when the user submits a valid form', () => {
  beforeEach(() => {
   /*
    * preconditions
    */
   })

  it('should enable the submit button', () => {
    expect(getFormSubmitButton(wrapper).attributes('disabled')).toBe(undefined)
  })

  it('should register the user by calling external API', () => {
    expect($auth.registerUser).toHaveBeenCalledWith({ email: validEmail })
  })

  it('should emit the "register-update" event', () => {
    expect(wrapper.emitted()['register-update'][0]).toBe(registerUserResponse)
  })
})
