几天以来,我一直在为我们的MultiDex-Application中的NoClassDefFoundError和AndroidJUnitRunner奋斗...
因为我们要开始使用Espresso进行点击测试,所以我们将TestRunner从“ MultiDexTestRunner”更改为“ AndroidJUnitRunner”。通过此更改,我们在API 19之下的设备上遇到了一些问题。当执行@SmallTests时,我们得到的响应是NoClassDefFoundError的原因“未执行测试”
在我们的Logcat中,我们获得以下信息:

这是我们的WakefulTestRunner所需的部分:
public class WakefulTestRunner extends AndroidJUnitRunner {
private PowerManager.WakeLock wakeLock;
private KeyguardManager.KeyguardLock keyguardLock;
@SuppressWarnings("deprecation")
@Override
public void onCreate(Bundle arguments) {
MultiDex.install(getTargetContext());
super.onCreate(arguments);
String simpleName = WakefulTestRunner.class.getSimpleName();
// Unlock the device so that the tests can input keystrokes.
keyguardLock = ((KeyguardManager) getContext().getSystemService(KEYGUARD_SERVICE)).newKeyguardLock(simpleName);
// Wake up the screen.
int levelAndFlags = android.os.PowerManager.FULL_WAKE_LOCK
| android.os.PowerManager.ACQUIRE_CAUSES_WAKEUP
| android.os.PowerManager.ON_AFTER_RELEASE;
wakeLock = ((PowerManager) getContext().getSystemService(POWER_SERVICE)).newWakeLock(levelAndFlags, simpleName);
}
@Override
public void onStart() {
runOnMainSync(new Runnable() {
@Override
public void run() {
keyguardLock.disableKeyguard();
wakeLock.acquire();
}
});
super.onStart();
}
我们还在build.gradle中排除了很多不同的东西,但是没有任何帮助:
configurations {
// This dependency set is for annotation processors.
// They're added below directly to the java compiler.
apt
androidTestCompile.exclude group: 'com.android.support', module: 'support-v4'
androidTestCompile.exclude group: 'com.android.support', module: 'recyclerview-v7'
androidTestCompile.exclude group: 'com.android.support', module: 'support-v13'
androidTestCompile.exclude group: 'com.android.support', module: 'appcompat-v7'
androidTestCompile.exclude group: 'com.android.support', module: 'cardview-v7'
}
defaultConfig {
minSdkVersion 15
targetSdkVersion 23
versionCode versionMajor * 10000 + versionMinor * 100 + versionMicro
versionName "${versionMajor}.${versionMinor}.${versionMicro}"
multiDexEnabled true
//intended to fix install issue -505 (https://code.google.com/p/android/issues/detail?id=189079)
applicationId = "com.xxxxxxxx"
testInstrumentationRunner "com.xxxxxxxxx.test.WakefulTestRunner"
}
最佳答案
这是AndroidJUnitRunner中的错误。

解决方法是不要在API 19之前的设备上使用测试尺寸标志。
api
./gradlew connectedAndroidTest -Pandroid.testInstrumentationRunnerArguments.size=small
适用于所有设备
./gradlew connectedAndroidTest
