java - Android Instrumentation 在使用 AndroidJunitRunner 和 AndroidJUnit4 时测试 java.lang.UnsatisfiedLinkError

Question

我在单元测试中使用了 robolectric。最近在我们的项目中，我们添加了一个来自 zendesk 的新依赖项。

repositories {

    maven {
        url 'https://zendesk.artifactoryonline.com/zendesk/repo'
    }
}

compile group: 'com.zendesk', name: 'sdk', version: '1.3.0.1'

现在我们甚至没有从这个库中引用任何类，我们只是通过添加这个依赖项在我们的 robolectric 单元测试中得到异常。我认为问题出在我们的项目中，但它也发生在示例机器人测试项目中。

Answer 1

找到了解决办法。我们没有在我们的测试用例中使用 zendesk 代码。来自添加的依赖项 (zendesk) 的广播接收器通过 gradle 构建添加到 AndroidManifest.xml。RobolectricTestRunner 类将 list 解析为其内部 ApplicationManifest 对象，然后通过 ShadowApplication 类设置应用程序状态。 ShadowApplication 类从应用程序 list 中注册广播接收器。这就是我遇到上述错误的地方。

修复:我们有一个扩展 RobolectricGradleTestRunner 的自定义测试运行器。因为我已经覆盖了 getAppManifest 方法并删除了不需要的广播接收器。我知道这是一种解决方法，但别无选择。不想创建另一个 list 并创建重复项。这是代码 fragment 。

@Override
protected AndroidManifest getAppManifest(org.robolectric.annotation.Config config) {
    AndroidManifest manifest = super.getAppManifest(config);
    List<BroadcastReceiverData> broadcastReceivers = manifest.getBroadcastReceivers();
    List<BroadcastReceiverData> removeList = new ArrayList<>();
    for(BroadcastReceiverData receiverData : broadcastReceivers) {
        if(isDeletePackage(receiverData.getClassName())) {
            removeList.add(receiverData);
        }
    }
    broadcastReceivers.removeAll(removeList);
    return  manifest;
}

private boolean isDeletePackage(String className) {
    for(String s : DELETE_BROADCAST_PACKAGE) {
        if(className.startsWith(s)) {
            return true;
        }
    }
    return false;
}

DELETE_BROADCAST_PACKAGE 只是一个字符串哈希集。包含包层级名称
