如何测试androidx.fragment.app.fragment.onCreateOptions菜单（）？

我很难将一些旧的Robolectric 3.x测试转换为新的样式（同时也转换为AndroidX）

我的设置： -Android Gradle插件3.2.1 -机器人分子4.1

一些相关配置（gradle.properties）：

注意，我没有使用android.enableUnitTestBinaryResources（因为在这个版本的android Gradle插件中，它在Windows上不起作用）

我的片段（片段）：

key_details_actions.xml（完整）：

堆栈跟踪：

android.content.res.Resources$NotFoundException: File D:\Git\xxx\application\build\intermediates\merged-not-compiled-resources\debug\drawable\ic_return_key_wrapper.xml from drawable resource ID #0x7f0800d5

    at android.view.MenuInflater.inflate(MenuInflater.java:110)

您还应该在

android

DSL的下一行：

   testOptions {
     unitTests {
       returnDefaultValues = true
       includeAndroidResources = true
     }
   }

我再也不能复制这个（Android Gradle插件3.3.2和Robolectric 4.2.1）
