Overview

When using verify to check if a mocked function has been called, if such function accepts a NSUserActivity as a parameter passed , and it has been passed as any(), the unit tests project crashes raising on the current latest version (0.19.2) a Thread 1: EXC_BAD_ACCESS.

On 0.18.x the error is also present, but is handled so that the project does not crash resulting into a failing test with a provided description and highlighting the specific line where the exception is raised: -[NSProxy methodSignatureForSelector:] called! (NSInvalidArgumentException)

On the 0.17.0 version the tests proceed without any issue.

Example

Protocol Function example:
func scene(_ scene: UIScene, continue userActivity: NSUserActivity)

Code that raises the exception/error:
verify(mockBranchClient.scene(any(), continue: any())).wasNeverCalled()
verify(mockBranchClient.scene(any(), continue: any())).wasCalled()

Expected Behavior

The test should either succeed or fail by check if the verified function has been called or not with the passed parameters.

Environment

• Xcode 13.2 Swift 5.5.2
• Mockingbird set up using pods and using the CLI bundled with it.
• Using Quick and Nimble

Thanks for reporting. Unfortunately I wasn’t able to repro this crash (see the changes under Examples/CocoaPodsExample): https://github.com/andrewchang-bird/mockingbird/tree/repro-issue-276

Could you provide additional context or a minimal repro project for this?

@andrewchang-bird I also stumbled on the same issue in 0.20.0 trying to mock a protocol which references NSDecimalNumber.

I reproduced the crash with a basic example in a fresh Carthage project.

// App target
protocol NSProtocol {
  func calculateSomething(from: NSDecimalNumber) -> String
}

// In test
let m = mock(NSProtocol.self)
given(m.calculateSomething(from: any())) ~> "test" // any() crashes
