使用Robolectric和androidx.Testing测试BottomSheetDialog项click（）

我正在尝试使用androidx.test和Robolectric测试BottomSheetDialog，但在尝试单击对话框中的按钮时遇到了问题

   onView(withId(R.id.fab_add)).perform(click())
   onView(withId(R.id.button_add_activity))
         .inRoot(isDialog())
         .check(matches(isClickable()))

   onView(withId(R.id.button_add_activity))
         .inRoot(isDialog())
         .perform(click())

我通过点击按钮打开对话框，然后，我可以验证BottomSheetDialog中的按钮是否存在，但是单击失败，原因是：java.lang.RuntimeException:操作将不会执行，因为目标视图与以下一个或多个约束不匹配：至少90%的视图区域显示给用户。。检查项目时显示高度/宽度为0

我尝试过设置固定大小，并在显示工作表的单击和工作表内的单击按钮之间睡觉。我还尝试了一些不同的布局选项

private fun onAddItemClick() {
    val dialogView: View = layoutInflater.inflate(R.layout.bottom_sheet_agenda_add, null)
    val dialog = BottomSheetDialog(requireContext())

    dialogView.button_add_activity.setOnClickListener {
        dialog.dismiss()
        // Do action
    }
    dialogView.button_add_availability.setOnClickListener {
        dialog.dismiss()
        // Do action
    }
    dialogView.button_add_job.setOnClickListener {
        dialog.dismiss()
        // Do action
    }
    dialog.setContentView(dialogView)
    dialog.show()
}
