Mockito + Dexmaker on Android 2

Question

>我看到了这个问题：Mockito + Dexmaker on Android

使用答案后，我遇到了另一个问题：java.lang.RuntimeException： java.lang.IllegalArgumentException： 优化的数据目录/sdcard 不属于当前用户。共享存储无法保护应用程序免受代码注入攻击。

我使用最新版本的mockito和dexmaker以及dexmaker-mockito。

我正在使用一个单独的测试项目。

完整的堆栈跟踪（testParse是我的测试函数）：

Answer 1

我在 http://code.google.com/p/dexmaker/issues/detail?id=2 上找到了解决方案

有效的方法是将以下行放入 setUp（）：

System.setProperty("dexmaker.dexcache", getInstrumentation().getTargetContext().getCacheDir().getPath());

让我们希望尽快进行修复，而不是使用此解决方法。

Answer 2

//Depending on the type of test, you can also do this:
System.setProperty("dexmaker.dexcache", getContext().getCacheDir().getPath());
