如何在Xcode 10和macOS 10.14下启动WireMock for XCTest UI测试？

我们正在使用独立的Wiremock实例作为Xcode UI测试的模拟服务器。我们有一个测试观察者类，负责分解该实例（如果需要），并在测试运行完成时将其拆解。观察者的代码如下：

import AppKit
import XCTest
import WiremockClient

class SSUITestObserver: NSObject, XCTestObservation {

    enum TestObserverError : Error {
        case MockServerStartupError(String)
    }

    lazy var testBundleURL: URL = Bundle(for: SSUITestCase.self).bundleURL
    lazy var testBundleBinURL: URL = self.testBundleURL.appendingPathComponent("..", isDirectory: true)
    lazy var mockServerHomeURL: URL = self.testBundleURL.appendingPathComponent("Contents/Resources/", isDirectory: true)
    lazy var mockServerJarURL: URL = self.mockServerHomeURL.appendingPathComponent("wiremock-standalone-2.18.0.jar", isDirectory: false)

    override init() {
        super.init()

        NSLog("UI Test Observer Initialized")
        XCTestObservationCenter.shared.addTestObserver(self)
    }

    func testBundleWillStart(_ testBundle: Bundle) {
        NSLog("***Test Bundle starting")
        do {
            // Start the Wiremock server
            try ensureMockServerIsRunning()
        } catch {
            fatalError("\n Failed during test bundle setup: \(error)\n")
        }


    }

    public func testBundleDidFinish(_ testBundle: Bundle) {
        NSLog("***Test Bundle completed")
        stopMockServer()
    }

    func ensureMockServerIsRunning() throws {
        WiremockClient.baseURL = SSUIIntegrationTestCase.mockServerAddress

        guard !WiremockClient.isServerRunning() else { return }

        let args = ["-jar",
                    self.mockServerJarURL.path,
                    "--port", "3000",
                    "--root-dir", self.mockServerHomeURL.path]

        _ = Process.launchedProcess(launchPath: "/usr/bin/java", arguments: args)

        for _ in 1...9 {
            if WiremockClient.isServerRunning() { return }
            sleep(1)
        }

        throw TestObserverError.MockServerStartupError("Error staring up the mock server instance!")
    }

    func stopMockServer() {
        WiremockClient.shutdownServer()
    }

    func resetMockServerStubs() {
        WiremockClient.reset()
    }
}

一切顺利，直到我移至macOS 10.14。以前，我们不是在代码上签名UITest目标。移至10.14后，运行测试现在会因启动错误而失败，甚至无法开始运行测试。我发现在测试中打开自动代码签名可以解决此问题。

但是，这导致了第二个问题：在launchedProcess上面的行中，启动Wiremock服务器的尝试将失败java.lang.RuntimeException: java.net.SocketException: Operation not permitted。如果在执行测试之前启动了服务器（例如，在命令行上），则一切正常。

那么，如何才能使自己摆脱22号陷阱？在10.13以下，一切正常。我不清楚启动模拟服务器与代码签名有什么关系。
