ios - WKWebView 进程在 CI 中终止但不在本地

Question

WKWebView当我在单元测试中加载页面时，内容进程 100% 崩溃。

它们在我的开发计算机上正常运行，但是当我在持续集成中运行测试时WKWebView不断调用。webViewWebContentProcessDidTerminate:这会导致测试失败。这是 CI 的输出：

Child process terminated with signal 11: Segmentation fault
Test crashed while running.

我正在使用 Buckbuck test在本地和 CI中构建和运行单元测试。

据我所知，我的机器和 CI 机器最大的区别是：

1. 用于 CI 的 Xcode 10.2，我的计算机上的 Xcode 10.3
2. CI 运行的单元测试比我的要多得多，因此可能会从其他测试套件中溢出。

我现在正在努力解决这些差异。WKWebView但是，在我的计算机上正常工作时，什么样的事情可能会导致CI​​ 上的内容进程崩溃？

谢谢！
