Alamofire tests failing

[pietrocaselani]

Hey!

I was showing your project to my team and I found some failing tests.

So, I cloned the project and ran the tests and some tests on AlamofireAsyncTests failed.
I notice that the failing tests are those that check for failing responses, with the message saying that expect TestError but got nil instead.

I tried to fix it with the code below

let testError = NSError(domain: "AsynchronousTests", code: 0, userInfo: nil)

func testDataRequestResponseFailure() {
    let expected = testError

    stub(everything, failure(expected as NSError))

    wait { expectation in
        Alamofire.request(fakeURL).response().async { result in
            switch result {
            case .success(let (_, _, value)):
                XCTFail("Unexpected value \(value)")
            case .failure(let actual):
                XCTAssertEqual(expected, actual.error as NSError)
            }
            expectation.fulfill()
        }
    }
}

but got this error

XCTAssertEqual failed: ("Error Domain=AsynchronousTests Code=0 "(null)"") is not equal to ("Error Domain=AsynchronousTests Code=0 "(null)" UserInfo={_NSURLErrorRelatedURLSessionTaskErrorKey=(
    "LocalDataTask <0063E615-BE9B-4022-AC07-1F06C14BDF97>.<1>"
), _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <0063E615-BE9B-4022-AC07-1F06C14BDF97>.<1>}")

So I think Mockingjay is returning another error or something like this. I looked at Mockingjay tests and here they are just verifying the error's domain.
Should we do the same maybe?

Also, I tried calling super.setUp here but the results were the same.

I running with this environment

Xcode 11.2.1
Build version 11B500

Could you please take a look at this?

Thanks!
