Arg.eq(protocol)

How to do that since I cant make a protocol extends MockUsable?

@pirishd Hello? Could you help me?

hi, @igordeoliveirasa the trick is to have a class or a struct which will conform to both a protocol of an argument which you want to constraint and MockUsable

protocol URLProtocol {}
class URLProtocolStub: URLProtocol {}
extension URLProtocolStub: MockUsable {
    public static let anyValue: MockUsable = URLProtocolStub()
    
    public func equal(to value: MockUsable?) -> Bool {
        if let value = value as? Self {
            return self === value
        }
        return false
    }
}

class NetworkClientMock: Mock {
     func fetch(from url: URLProtocol) {
          super.call(url)
     }
}

func test() {
     let mock = NetworkClientMock()
     let urlStub = URLProtocolStub()
     mock.expect().call(mock.fetch(from: Arg<URLProtocolStub>.eq(urlStub)))
}
