Currently Swift Testing has much less features than XCTest, so the adoption will be very slow from our side. Notable features we miss are UI tests, performance tests and attachments. I did not want to create many issues in Swift Testing GitHub project as lots of these shortcoming are most probably tracked internally (I can see lots of references to radars in GitHub issues.) So, my question is: Is it a good idea to wait with wider adoption or should we experiment with other tools like swift Benchmarks?

Is it a known issue that when attempting to test SwiftData objects with relationships in Swift Testing there are errors that do not occur when the app is running? Example: @Relationship(deleteRule: .cascade, inverse: \MBAccount.book) var accounts: [MBAccount] = [] and @Relationship var book: Microbook? Then the test: let book = Microbook(name: "Julia's Cupcakes") let account1 = MBAccount(name: "Chase Business Account") let account2 = MBAccount(name: "Cash Drawer") account1.book = book account2.book = book #expect(account1.name == "Chase Business Account") #expect(account2.type == "asset") } Produces a fatal error while running test: SwiftData/PersistentModel.swift:321: Fatal error: Unable to find relationship on MBAccount for KeyPath \MBAccount.book Any ideas?

Hello everyone, I’m encountering an issue with my Swift Testing suite where state changes made in one test method do not persist to another. I am using Swift’s @Suite and @Test annotations to group and serialize my tests, but it seems that the state is not being carried over between the tests. The second function fails with: Expectation failed: (string → nil) != nil Here is my example code: import Testing @Suite(.serialized) struct createCheckTests { var value = 25 var string: String? = nil @Test("Create string") mutating func stringCreation() { #expect(value > 0) string = "Value is: \(value)" } @Test("Check string") func stringCheck() { #expect(string != nil, "The string is nil") print("\(String(describing: string))") } } What is the correct way to approach such a scenario where I want to test two functions that are related, one to generate some value and one to check that generated value against it initial value using Suites to group and isolate them from other tests? Thanks.

From the Documentation of .timeLimit(_:): Test timeouts do not support high-precision, arbitrarily short durations due to variability in testing environments. The time limit must be at least one minute, and can only be expressed in increments of one minute. Unit Tests are usually considered too long when they take more than 0.1 seconds. So a minimal time limit of on minute is completely useless for unit tests. Is there a similar trait in Swift Testing to handle millisecond time limits?
