並補充對改代碼的優化

}2.在Androidmainfest.xml文件中需要進行修改：
原來代碼顯示爲：
<instrumentation
android:name="android.test.InstrumentationTestRunner"
android:targetPackage="com.被測app包名.cn" /><instrumentation android:name="com.targtime.mtll.testResult.SampleTestResult"
android:targetPackage="com.被測app包名.cn" />
3.編寫完成後，需要在eclipse中右鍵運行時選擇“run configurations”-junit-中的需要運行的測試類名，並在test中設置“run時選用的
InstrumentationTestRunner爲最新創建的“SampleTestResult類”
4.運行後進入手機SD卡中超找文件，並導出本地結果進行查看
補充：
5.因爲多個類可以需要同時運行，所以需要建立一個“TestSuite”類
public class SampleTestSuite extends TestSuite {
public static Test suite() {
TestSuite ts = new TestSuite();
ts.addTestSuite(Test1.class);
ts.addTestSuite(Test2.class);
return ts;
}
}
