我想为我的安卓应用程序创建一些简单的测试,但是在运行测试时遇到了问题。我一直在尝试运行测试时都会收到NoClassDefFound错误,但是我似乎无法找出其原因。如果可以,请帮忙查看一下。
编辑:这是项目结构的图片:
以下是我一直收到的错误信息:

相机测试
package nl.hanze.myhealth;
import android.test.ActivityInstrumentationTestCase2;
import android.test.suitebuilder.annotation.SmallTest;
public class CameraTest extends ActivityInstrumentationTestCase2<ScanResultActivity> {
ScanResultActivity mActivity;
public CameraTest(){
super(ScanResultActivity.class);
}
@Override
protected void setUp()throws Exception{
super.setUp();
mActivity = getActivity();
}
@SmallTest
public void testScanResultNotNull(){
boolean test = mActivity.generateScanResult();
assertNotNull(test);
}
@Override
protected void tearDown() throws Exception{
super.tearDown();
}
}
扫描结果活动
package nl.hanze.myhealth;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import java.util.Random;
public class ScanResultActivity extends Activity {
Random rand = new Random();
public ScanResultActivity(){
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_scan_result);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.scan_result, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
protected boolean generateScanResult(){
boolean positive_scanresult;
int max = 10;
int min = 1;
int randomNum = rand.nextInt((max - min) + 1) + min;
if(randomNum >= 6){
positive_scanresult = true;
}else{
positive_scanresult = false;
}
return positive_scanresult;
}
}
package nl.hanze.myhealth;
中,而不是在测试包中。 - dragi(java.lang.NoClassDefFoundError: nl.hanze.myhealthtests.ScanResultActivity)
。那么你在哪里定义了nl.hanze.myhealthtests
? - dragi
