Java Robolectric 3.0返回空指针

我正在尝试将Robolectric升级到3.0。我正在使用

RobolectricGradeleteStrunner

，并且在我的测试类上方添加了

@Config（constants=BuildConfig.class）

。我还尝试过使用

testCompile org.roblectric:roblectric:3.1-SNAPSHOT

。下面是我在日志中看到的堆栈跟踪

我也有类似的问题。我不知道是什么导致了这些问题，但是如果我的testclass被注释为

@RunWith(RobolectricGradleTestRunner.class)
@Config(emulateSdk = 19, constants = BuildConfig.class)

---

请尝试使用

gradletestcompile

从控制台运行它，我遇到了类似的问题。我不知道是什么导致了这些问题，但是如果我的testclass被注释为

@RunWith(RobolectricGradleTestRunner.class)
@Config(emulateSdk = 19, constants = BuildConfig.class)

请尝试使用

gradle testCompile

将代码格式添加到堆栈跟踪以提高可读性。将代码格式添加到堆栈跟踪以提高可读性。我使用以下命令从命令行运行：./gradlew testDebug-Dpre dex=false--info--stacktrace I我仍然看到相同的问题。我使用以下命令从命令行运行：./gradlew testDebug-Dpre dex=false--info--stacktrace我仍然看到相同的问题。
