Allow to pass a delegate to Wrapping()

In certain test scenarios on our side we want to set up fake calls for a wrapping fake before the actual application started and the actual object to be wrapped becomes available.

It would be great to have an overload for Wrapping() that takes a delegate to allow the following:

1. Set up fake object wrapping a delegate that returns a field which is currently null
2. Start the subject-under-test application
3. Obtain the object-to-be-wrapped from the application and save it to the field
4. Any calls to the fake which are not set up are now passed on to the delegate -> to the field

Best regards, D.R.

Congratulations, @drauch! Happy fathering!

On to business. Because I still don’t understand, it sounds to me like at the time you decide to swap in the Fake, you already have access to the original service that you’d be wrapping. I’m sure I’m still missing something, because if it were that easy, you wouldn’t be here. Still, we at FakeItEasy Canada don’t understand the situation in which this feature would apply, nor how far-reaching the benefit would be.

I propose that until you (or maybe one of your teammates, since it sounds like this is a work project) can show up with an example, or very detailed explanation of the flow (which we can ask annoying questions about), we close the issue. And then it can be reopened when there’s more information.

That’s correct, yes.
