We use convenience initialisers in order to provide reusable mocked instances:

The compiler is warning us of:

'given' is deprecated: Use given(_ service:) instead. 

However when replacing with:

convenience init(metadata: SpotlightMetadataModel, isInWatchlist: Bool) {
  self.init(policy: .relaxed)
  given(self)

We get the following error:

Use of 'given' refers to instance method rather than global function 'given' in module 'Mockable'
