Xcode tests stuck in testing state

I had the same issue. Don't know if it had any effect, but I moved Xcode from my Downloads folder to Applications, then tried again. It did get stuck, so I started looking at Console to see if there were any clues. While I was doing this the tests eventually started. Took about 5 minutes?

Also had the same issue, what worked is deactivating the "Execute in parallel" in the Tests options (Edit scheme -> Choose Test -> Select Test Plan and go to Options)

The same issue

Same here. In addition, when I opened Console, there were a constant stream of Xcode errors similar to this: "found no value for key DVTShowAllSimulatorRunDestinations in CFPrefsSearchListSource<0x600000679780> (Domain: com.apple.dt.Xcode, Container: (null))" Switching off the "Execute in parallel (if possible)" option helped to run tests, but the errors stream in console didn't stop. Xcode Version 15.0 (15A240d).

I have the same problem Xcode 14.3.1, the workaround (disable running tests in parallel) didn't help.

Maybe you use in your XCTestCase

override func setUp(completion: @escaping ((any Error)?) -> Void) { }

    override func tearDown(completion: @escaping ((any Error)?) -> Void) {} 

and never call the completion(), to let it continue

also you can forget to use

expectation.fulfill()

, that in some chain never called, when you use:

let expectation = self.expectation(description: "testCurrentUser")
waitForExpectations(timeout: 5, handler: nil)

Hey, I encountered the same issue with Xcode 15.3 as well. I tried fixing it, but unfortunately, it didn't work for me either.

Here is the sample code:

import XCTest @testable import Dummy

final class CryptoDataAPIResorucesUnitTests: XCTestCase {

func test_CoinAPIResources() {
    let resources = CoinAPIResources(httpUtility: HttpUtility())
    let expectation = self.expectation(description: "CoinAPIResources")
    
    resources.getCoinList { coinData, errorMessage in
        XCTAssertNotNil(coinData)
        XCTAssertNil(errorMessage)
        expectation.fulfill()
    }
    waitForExpectations(timeout: 5)
}

}
