手工测试过程中有个测试场景需要删除测试设备上某个Android feature,往上搜索了一圈没找到有效的操作方法。获取Android设备所有的feature可以通过adb命令pm list features或者Android代码Context.getPackageManager().getSystemAvailableFeatures(),但都没有对应的修改方法。
既然feature是从Context获取的,那能不能构造一个只包含我想要的feature的Context呢。顺着这个思路,有了下面的方案。
单元测试常用的Mock技术,就是来构造假/模拟对象的。但如果完全构造,又担心和真实环境差别较大,测试结果不可靠。能不能从真实Android设备中获取真实的Context,把不想要的feature去除,再给到被测试方法中呢?
答案是肯定的,通过选用流行的Mock组件Mockito ,官网上给出了下面2种Mock Java对象的方式:
mock()
/@Mock
: create mockspy()
/@Spy
: partial mocking, real methods are invoked but still can be verified and stubbed可以看到Spy这种Mock方式可完美地解决我的需求。
获取所有Android Features并把feature name打印在日志中,使用adb命令的效果如下:

Log.i(TAG, "feature: " + featureInfo.name);
}
}
}
@Spy
Context context = InstrumentationReGIStry.getInstrumentation().getTargetContext();;
@Spy
PackageManager packageManager = context.getPackageManager();
@Test
public void getFeatures() {
// 去除bluetooth feature
FeatureInfo[] mockedFeatureInfos = removeFeature(packageManager.getSystemAvailableFeatures(),
Arrays.asList("android.hardware.bluetooth", "android.hardware.bluetooth_le"));
when(packageManager.getSystemAvailableFeatures()).thenReturn(mockedFeatureInfos);
when(context.getPackageManager()).thenReturn(packageManager);
FeaturesUtil.getFeatures(context);
}
private FeatureInfo[] removeFeature(FeatureInfo[] featureInfos, List<String> featureNames) {
List<FeatureInfo> featureInfoList = new ArrayList();
for (FeatureInfo featureInfo :
featureInfos) {
if (featureInfo.name != null && !(featureNames.contains(featureInfo.name))) {
featureInfoList.add(featureInfo);
}
}
return featureInfoList.toArray(new FeatureInfo[featureInfoList.size()]);
}
可以看到bluetooth相关的feature已经没有了
