android - Robolectric : NotFoundException: unknown resource 0 at org. robolectric.shadows.ShadowAssetManager.getAndResolve (ShadowAssetManager.java:258)

Question

我在测试 getView 时遇到错误。测试代码在测试用例期间调用 View.setImageResource(0) 以在异常发生时设置空图像。

我用 Eclipse 运行了测试 robolectric-2.2-20130712.161723-17-jar-with-dependencies.jar。我尝试用 ShadowResources.createFor(new ResourceLoader() {...} 替换 ResouceLoader。但它不起作用。我替换的 ResouceLoader 没有被调用。

有人知道怎么解决吗？

我的 Apdater ContentDetailsAdapter 机器人单元测试中的另一个类似问题来自语句 mContext.getResources().getString(R.string.delete_hint_title)。 mContext 由 Robolectric.getShadowApplication().getApplicationContext() 创建。我关于 Roboletric 的配置有问题吗？我能够在我的单元测试中调用 ProgressDialog.show(mContext, "", "") 。看来问题总是出在资源上。这是堆栈:

我遇到了与您的第二期类似的错误。我的环境是根据 http://www.youtube.com/watch?v=3mjcg5gfDLE 设置的

提供的示例适用于我的 Eclipse，但是当我尝试将 MyProjectTest 链接到我自己的应用程序时，出现了您描述的第二个错误。

视频在 6:00 描述了解决方案。

MyProjectTest -> Run As Configuration -> JUnit -> MyProjectTestConfiguration -> Arguments -> 单击“Other”单选按钮 -> Workspace -> 选择

要点是:如果您为不同的应用程序运行 robolectric 测试，则必须将“工作目录”指向它。此外，您需要将您的测试文件夹从 MyProjectTest 链接到 .
