android - 如何编写“JUnit 测试用例”android？

Question

我想学JUnit Tesing安卓。我做谷歌，现在我知道如何创建 JUnit 测试用例。但是我的问题是如何在那个类中编写逻辑，我不知道。

假设我想为自定义的listview编写测试用例，那我该如何实现呢？请给我一些指导。

public class CustomlistviewActivityTest extends TestCase {

protected void setUp() throws Exception {
    super.setUp();
}

protected void tearDown() throws Exception {
    super.tearDown();
}

public void testOnCreateBundle() {       // this is oncreate method
    fail("Not yet implemented");
}

public void testOnCreateContextMenuContextMenuViewContextMenuInfo() {
    fail("Not yet implemented");     // this method is for the create the context menu
}

public void testOnContextItemSelectedMenuItem() {
    fail("Not yet implemented");     // this method is for the select the item of the context menu
                //   on select items call the below method named testFunction1()
}

public void testFunction1() {
    fail("Not yet implemented");     // display toast
}

public void testFunction2() {
    fail("Not yet implemented");        // display toast
}

public void testOnItemClick() {
    fail("Not yet implemented");          // display toast
}

}

谢谢。
