当我运行应用程序时，到达 Alamofire 响应块没有问题。当使用 OHHTTPStubs 运行测试和模拟响应时，两个存根块（请求和响应）都会被调用，但 Alamofire 响应块永远不会被调用，因此测试失败。用 URLRequest 尝试了完全相同的存根，响应块被称为没有问题。

api类：

private static var config: URLSessionConfiguration?
private static var session: SessionManager?

static var instance = getInstance()

private static func getInstance() -> Api {
    let api = self.init()
    return api
}

private init() {
    Api.config = URLSession.shared.configuration
    var headers = SessionManager.defaultHTTPHeaders
    headers.removeValue(forKey: "User-Agent")
    headers["User-Agent"] = APP_VERSION
    Api.config?.httpAdditionalHeaders = headers
    Api.session = SessionManager(configuration: Api.config!)
}

func requestFunction(_ path: String) {
    let req = Api.session!.request("\(apiUrl())\(path)", method: .get, parameters: request.toJSON()).response(completionHandler: completionHandler)
}

测试：

func test() {
    stub(condition: { (request) -> Bool in
            return true
        }) { (request) -> OHHTTPStubsResponse in
            return OHHTTPStubsResponse(
                jsonObject: self.usageResponse,
                statusCode: 200,
                headers: ["Content-Type":"application/json"]
            )
        }

    let semaphore = DispatchSemaphore.init(value: 0)
    Api.instance.requestFunction(path, { (_, _) in
        semaphore.signal()
    })

    let timeout = DispatchTime.now() + DispatchTimeInterval.seconds(300)
    if semaphore.wait(timeout: timeout) == DispatchTimeoutResult.timedOut {
        XCTFail("semaphore not reached")
    }
}

信号量永远达不到。但是，如果我不调用 Alamofire 而不是这样做，那么信号量就没有问题了：

    do {
        let request = try URLRequest.init(url: "www.w.com", method: .post)
        let configuration = URLSessionConfiguration.default
        let session = URLSession(configuration: configuration)
        let task = session.dataTask(with: request) { (_, _, _) in
            semaphore.signal()
        }
        task.resume()
    } catch {

    }

不确定你在Api.instance某个地方打过电话。但似乎您没有使用Api类的共享实例，但您正在初始化private init()方法中的所有内容。

class Api {
    private var config: URLSessionConfiguration?
    private var session: SessionManager?

    static let shared = Api()

    private init() {
        config = URLSession.shared.configuration
        var headers = SessionManager.defaultHTTPHeaders
        headers.removeValue(forKey: "User-Agent")
        headers["User-Agent"] = APP_VERSION
        config?.httpAdditionalHeaders = headers
        session = SessionManager(configuration: Api.config!)
    }

    func requestFunction(_ path: String) {
        let req = session!.request("\(apiUrl())\(path)", method: .get, parameters: request.toJSON()).response(completionHandler: completionHandler)
    }
}

测试应该是

func test() {
    ...

    Api.shard.requestFunction(path, { (_, _) in
        semaphore.signal()
    })

    ...
}
