Robolectric 3.3.2 Facebook 4.3及更高版本的兼容性问题

Question

我在使用特定版本的Robolectric和Facebook运行单元测试时遇到了问题。当我满足以下条件时，我的测试脚本才能工作

testCompile "org.robolectric:robolectric:3.3.2"
testCompile "org.robolectric:shadows-multidex:3.3.2"
testCompile 'org.robolectric:shadows-support-v4:3.3.2'

和

compile 'com.facebook.android:facebook-android-sdk:4.2.0'

但是，当我升级到

compile 'com.facebook.android:facebook-android-sdk:4.22.0'

我得到了以下问题：

WARNING: unknown service appops
WARNING: no system properties value for persist.radio.multisim.config

The Facebook sdk must be initialized before calling activateApp

你知道怎么解决这个问题吗？

Answer 1

从4.19开始，Facebook SDK会自动初始化进程。Robolectric不能正确启动它，因此导致崩溃。

如果你不需要初始化Facebook SDK，一个完美有效的解决方案就是隐藏activateApp调用。创建此类：

@Implements(AppEventsLogger.class)
public class ShadowAppEventsLogger {
    @Implementation
    public static void activateApp(Application application) {
        // Do nothing, just shadow
    }
}

并将其附加到您的测试：

@Config(shadows = {ShadowAppEventsLogger.class, ...}, ... )
@Test public void fooTest() {...}
