我在 Travis 构建服务器上的 Robolectric 测试中得到以下 NPE，但我无法查明原因。我无法在本地重现此问题。

有人知道是什么原因导致 onServiceConnected 被调用吗？这可能有助于我查明问题。据我所知，这是一个 Google Play Services - Google Analytics 问题。

据我所知，我不会在任何地方为我的单元测试初始化​​ GA。我有一个通用的“假”分析跟踪器，每当运行测试时都会使用它。以防万一，我在我的假跟踪器的构造函数中添加了以下行，它是在应用程序的 onCreate 中创建的：

GoogleAnalytics.getInstance(context).setAppOptOut(true);

如果这是相关的，它会在 Java 1.7.0_u55 的盒子上打破。

编辑：

我今天在失败的测试日志中看到了以下内容。我不确定这是坠机的原因。可能会提供一些见解。

看起来像 SQLite 和 GA 的问题？

另一个更新：

有关更新，请参阅链接的 github 问题 ( https://github.com/robolectric/robolectric/issues/1075 )。我暂时恢复到 v3。

Akeem 的解决方案对我有用。

这是我用于 Robolectic 3.0 的，它有一些变化：

import org.robolectric.RuntimeEnvironment;
import org.robolectric.Shadows;
import org.robolectric.shadows.ShadowApplication;

ShadowApplication shadowApplication = Shadows.shadowOf(RuntimeEnvironment.application);
shadowApplication.declareActionUnbindable("com.google.android.gms.analytics.service.START");

解决方法是在所有测试套件中添加以下行（因为您不知道首先运行哪个测试用例）

ShadowApplication shadowApplication = Robolectric.shadowOf(Robolectric.application);
shadowApplication.declareActionUnbindable("com.google.android.gms.analytics.service.START");

或者，您可以为您的应用程序创建一个不绑定服务的自定义影子类：

import android.app.Application;
import android.content.Intent;
import android.content.ServiceConnection;
import android.util.Log;

import org.robolectric.annotation.Implementation;
import org.robolectric.annotation.Implements;
import org.robolectric.shadows.ShadowApplication;


@Implements(Application.class)
public class MyShadowApplication extends ShadowApplication {
    @Implementation
    public boolean bindService(Intent intent, final ServiceConnection serviceConnection, int i) {
        Log.d("Robolectric", intent.getAction());
        return false;
    }
}

并使用影子类运行所有测试用例

@Config(emulateSdk = 18, shadows = {MyShadowApplication.class})

这就是我想出的（并在我的情况下解决了）：某处（可能在初始化谷歌分析时），有一个启动服务的调用。

我认为这个调用是为了启动我的应用程序的一项服务，所以我添加了

Robolectric.getShadowApplication().setComponentNameAndServiceForBindService(
            new ComponentName(Robolectric.application, MyService.class),
            new StalkerService() {
                @Override
                public Context getApplicationContext() {
                    return Robolectric.application;
                }
            }.onBind(null)
    );

在我的 TestApplication 代码中，在调用super.onCreate. 很高兴，它解决了我的问题——不再有 NPE，并且所有测试都通过了。

但是，后来我注意到这是一个非常奇怪的解决方案，因为我为我的服务而不是 GA 服务提供 Robolectric 活页夹......但它有效，我不知道为什么。所以，我将把它留在这里，让你测试它是否也能解决你的问题。
