Adnroid单元测试

1.进行单元测试需要在Manifest.xml文件里添加如下内容：

（1）在application内添加

<uses-library android:name="android.test.runner"/>

（2）在application外添加

<instrumentation 
        android:name="android.test.InstrumentationTestRunner"
         android:targetPackage="com.archermind.activity"
         android:label="test by kelei"
         />

其中android:targetPackage="com.archermind.activity"要于manifest里的package="com.archermind.activity"一致

2.建立单元测试类，单元测试类继承AndroidTestCase类

public class StudentDAOTest extends AndroidTestCase
{

    private static final String TAG = "StudentDAOTest";

    public void testAdd()
    {
        StudentDAO studentDAO = new StudentDAO(this.getContext());
        Student student = new Student(1, "kelei");
        studentDAO.add(student);
        Log.i(TAG, "add success");
    }

    public void testUpdate()
    {
        fail("Not yet implemented");
    }

    public void testFind()
    {
        StudentDAO studentDAO = new StudentDAO(this.getContext());
        Student student = studentDAO.find(1);
        if(student==null)
        {
            Log.i(TAG, "not find");
        }
        else
        {
            Log.i(TAG, student.toString());
        }
    }
}
