Should you wrap XCTAssertNoDifference.swift inside #if DEBUG ?

[alejandrogarin]

Hi guys,

Since XCTAssertNoDifference.swift imports XCTestDynamicOverlay, I guess it should be wrapped inside #if DEBUG ?

Thanks.

Hey @alejandrogarin, in the dynamic overlay library we provide an empty implementation of XCTFail when not in DEBUG:

https://github.com/pointfreeco/xctest-dynamic-overlay/blob/0ec2d710978df8a73ae788b9897d2c189880de0f/Sources/XCTestDynamicOverlay/XCTFail.swift#L74-L93

Are you getting compiler errors when building for release? Can you make sure you are using the newest version by updating your packages?

Thanks for the reply.
I was going to update to TCA 0.25.1 and saw an issue in XCTestDynamicOverlay, I didn't notice the fact that we have an empty implementation !

Thanks!

Kind of related and I'm struggling to find an answer:
I am using an additional build configuration called Test which is a duplicate of Debug but I can't use XCTAssertNoDifference with it since all test just succeed no matter if there is a difference.

XCTAssertNoDifference("Blob", "Blob Sr.") -> ✅

The diff in XCTAssertNoDifference() is created correctly but when I reach the creation of let failure = ... its empty 🤷‍♂️
