Overview

I am wondering how to stub as a partial mock on class method, just like

let bird = type(of: mock(Bird.self))
bird.forwardCallsToSuper()

But i found the forwardCallsToSuper is only instance method in Mock extension

public extension Mock {
    @discardableResult
    func forwardCallsToSuper() -> Self {
        mockingbirdContext.proxy.addTarget(.super)
        return self
    }
}

Can i add the static method forwardCallsToSuper in Mock extension ？

public extension Mock {
    @discardableResult
    func forwardCallsToSuper() -> Self {
        mockingbirdContext.proxy.addTarget(.super)
        return self
    }

    @discardableResult
    static func forwardCallsToSuper() -> Self.Type {
        mockingbirdContext.proxy.addTarget(.super)
        return self
    }
}
