我想在Android Studio中製作一些Android Instrumentation類,以便測試我的ormlite類。 ormlite的DBHelper類需要從我的res/raw/ormlite_config.txt中的ormlite配置文件讀取,並使用R.raw.ormlite_config訪問。在Android Instrumentation中訪問R.raw資源jUnit測試

這不是我用openRawResource(R.raw.ormlite_config)得到的東西,因爲DBHelper的超類的構造函數需要int資源。

當我運行我的測試,它無法雖然找到它:

android.content.res.Resources$NotFoundException: Resource ID #0x7f090001

下面是完整的堆棧跟蹤:

android.content.res.Resources$NotFoundException: Resource ID #0x7f090001 
at android.content.res.Resources.getValue(Resources.java:1266) 
at android.content.res.Resources.openRawResource(Resources.java:1181) 
at android.content.res.Resources.openRawResource(Resources.java:1158)

at com.j256.ormlite.android.apptools.OrmLiteSqliteOpenHelper.<init>(OrmLiteSqliteOpenHelper.java:76) 
at com.inadaydevelopment.herdboss.DB.<init>(DB.java:40)

at com.inadaydevelopment.herdboss.ORMLiteTest.setup(ORMLiteTest.java:29)

at android.support.test.runner.AndroidJUnitRunner.onStart(AndroidJUnitRunner.java:262) 
at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1853) 

Tests ran to completion. 

的DBHelper:

public class DBHelper extends OrmLiteSqliteOpenHelper { 
    public DBHelper(Context context) { 
     super(context, DATABASE_NAME, null, DATABASE_VERSION, R.raw.ormlite_config); 
    } 
} 

我jUnit測試用例:

@RunWith(AndroidJUnit4.class) 
public class ORMLiteTest { 
    @Before 
    public void setup() { 
     DB.shared(InstrumentationRegistry.getContext()); 
    } 
} 

固定Commonsware的回答是:

@RunWith(AndroidJUnit4.class) 
public class ORMLiteTest { 
    @Before 
    public void setup() { 
     DB.shared(InstrumentationRegistry.getTargetContext()); 
    } 
}

getContext()androidTest/源集中返回Context指向資源。如果資源位於實際應用本身中(例如,main/源集),請使用getTargetContext()
