Is there a way to run XCTest (UI) against an archive build (.ipa)?

Question

I am learning how to use XCTest to close a gap in automation. From the developer doc, I see only something like this:

xcodebuild test -project MyAppProject.xcodeproj schema MyApp

https://developer.apple.com/library/tvos/documentation/DeveloperTools/Conceptual/testing_with_xcode/chapters/08-automation.html#//apple_ref/doc/uid/TP40014132-CH7-SW1

I would like to know if there is a way to run XCTest (UI test) against archive build (.ipa)? or Can we just separate the assembly and testing so that we can first build and test this assembly?

thanks
