I need to write about this thread on the Swift boards this week. The title, “A New Method to Testing in Swift”, and the authors being Developer Instruments and XCTest group members was sufficient to make this vital, however the content material is even higher.

XCTest is a superb testing framework. It has all it’s worthwhile to write every part from a few particular person unit exams to large check suites with hundreds. Exterior of some additions yearly, although, it has regarded and felt the identical for a very long time. This thread provides us a sneak peek at a successor to XCTest, and it’s an open-source bundle that Apple will develop in public! Even higher, we’re being allowed to see it at a really early stage. I’d suggest beginning by studying the imaginative and prescient doc, however there’s a lot within the repository to discover already. The group are on the lookout for suggestions, so please learn it and touch upon the thread. I can’t wait to see the way it develops. 🚀

I’ve dabbled with Fast and Nimble previously, and whereas I really feel very a lot at house with their strategy, I all the time fall off, although, due to how their exams combine with Xcode’s check reporting function. That’s not the fault of these two (or some other) testing libraries however a symptom of how tightly coupled XCTest and Xcode are.

I’m certain this new testing library will probably be great and turn into the de-facto testing resolution for Swift. Nevertheless, I additionally hope the combination between it and Xcode will probably be open to different testing frameworks. There are hints within the doc that time in direction of this being on the group’s thoughts, so I don’t suppose it’s out of the query. If that’s the case, I can see this ushering in a brand new period of incredible testing instruments for Swift along with this library.
