【问题描述】：
我们有 Mockito 版本 2.18.3。现在我升级到 3.5.13。
Robolectric 版本也从 3.8 升级到 4.4。
因此，在 700 次测试中，有一半因各种原因开始失败。其中之一是 mockito 无法创建 Context 类。
它现在无法模拟的其他类，例如，我们代码库的许多接口、类、android.app.Activity、android.location.Location。
任何帮助将不胜感激。谢谢！

You are seeing this disclaimer because Mockito is configured to create inlined mocks.
You can learn about inline mocks and their limitations under item #39 of the Mockito class javadoc.
