Android之单元测试——下

在项目中实际遇到的问题,和大家做一个分享.

#1.在控件的模拟事件执行的时候,尽量不要使用@UiThreadTest.因为如果一个Activity中,控件很多的话,很容易造成UI线程阻塞.

可以采用如下一段代码代替之：

private class PerformClick implements Runnable {         Button hhButton;         public PerformClick(Button HHButton) {             hhButton = HHButton;         }                  @Override         public void run() {             hhButton.performClick();         }     }

#2.怎样对控件进行压力测试,我的处理是不停的调用View的Click事件

public void stressTestForButton(final Button btn,int pressNumber) {         for(int i = 0;i <= pressNumber;i++) {             new Thread(new Runnable() {                 @Override                 public void run() {                     btn.requestFocus();                     btn.performClick();                     btn.clearFocus();                 }             });             Log.i("count times", i + "");         }     }

#3.对控件上显示字段的测试,显示的字段来自strings.xml

public void testText() {         //testing String values         assertEquals(hayhouseLinkButtonString, (String)hayhouseLinkButton.getText());         assertEquals(hayhouseradioLinkButtonString, (String)hayhouseradioLinkButton.getText());         assertEquals(healLinkButtonString, (String)healLinkButton.getText());     }

#4.怎样在Activity中对各个Button的压力测试,注意对线程的控制

public void testButtonStress() {         Log.v(TAG, "testButtonStress method is starting");         SystemClock.sleep(400);         new OperateUtil().new performButtonClickStress(hayhouseLinkButton,10);         SystemClock.sleep(400);         addClickTimes(hayhouseLinkButton,50);         SystemClock.sleep(400);         addClickTimes(hayhouseLinkButton,100);         SystemClock.sleep(400);         addClickTimes(hayhouseLinkButton,200);         SystemClock.sleep(400);         new OperateUtil().new performButtonClickStress(hayhouseradioLinkButton,10);         SystemClock.sleep(400);         addClickTimes(hayhouseradioLinkButton,50);         SystemClock.sleep(400);         addClickTimes(hayhouseradioLinkButton,100);         SystemClock.sleep(400);         addClickTimes(hayhouseradioLinkButton,200);         SystemClock.sleep(400);         new OperateUtil().new performButtonClickStress(healLinkButton,10);         SystemClock.sleep(400);         addClickTimes(healLinkButton,50);         SystemClock.sleep(400);         addClickTimes(healLinkButton,100);         SystemClock.sleep(400);         addClickTimes(healLinkButton,200);     }

#5.在tearDown()方法里面一般进行的操作。

@Override     protected void tearDown() throws Exception {         hayhouseLinkButton.clearFocus();         hayhouseLinkButton.clearComposingText();         hayhouseradioLinkButton.clearFocus();         hayhouseradioLinkButton.clearComposingText();         healLinkButton.clearFocus();         healLinkButton.clearComposingText();         detailView.clearFocus();                  hayHouseActivity.finish();         super.tearDown();     }

#6.在app跑起来前,要保证所有的widget不能为空。

public void testPreConditions() {        assertTrue(hayhouseLinkButton != null);        assertTrue(hayhouseradioLinkButton != null);        assertTrue(healLinkButton != null);        assertTrue(gobackButton_hayhouse != null);        assertTrue(detailView != null);    }

#7.怎样对一个Service进行测试。

/**  * From sdk description  *   * This test case provides a framework in which you can test Service classes   * in a controlled environment. It provides basic support for the lifecycle of a   * Service, and hooks with which you can inject various dependencies and   * control the environment in which your Service is tested.  */  public class AudioServiceTest extends ServiceTestCase {     private static final String TAG = "-----AudioServiceTest-----";          public AudioServiceTest() {         super(AudioService.class);     }      @Override     protected void setUp() throws Exception {         Log.i(TAG, "=====AudioServiceTest setUp Start=====");         super.setUp();                  Log.i(TAG, "=====AudioServiceTest setUp End=====");     }          /**      * 2011.09.16    jack.li add......      * test basic startup/shutdown of Service      */     @SmallTest     public void testStartable() {         Log.i(TAG, "+++++AudioServiceTest testStartable Start+++++");         Intent startIntent = new Intent();         startIntent.setClass(getContext(), AudioService.class);         startService(startIntent);         assertNotNull(getService());     }          /**      * 2011.09.16    jack.li add......      * test binding to service      */      @MediumTest      public void testBindable() {         Log.i(TAG, "+++++AudioServiceTest testBindable Start+++++");         Intent startIntent = new Intent();         startIntent.setClass(getContext(), AudioService.class);         IBinder service = bindService(startIntent);         assertNotNull(service);     }      }

#8.如何对android中数据库进行一个单元测试,这里我引用网上的一个案例
数据库的逻辑代码如下：

import java.text.SimpleDateFormat;    import java.util.ArrayList;    import java.util.Date;    import java.util.HashMap;    import java.util.List;    import java.util.Map;    import java.util.Random;       import android.content.ContentValues;    import android.content.Context;    import android.database.Cursor;    import android.database.DatabaseUtils;    import android.database.sqlite.SQLiteDatabase;       import com.android.hanhan.R;       public class DatabaseService {        private DatabaseHelper dbOpenHelper;        protected static final String TBL_NAME = "article";        protected static final String FIELD_ID = "id";        protected static final String FIELD_TITLE = "title";        protected static final String FIELD_CONTENT = "content";        protected static final String FIELD_DELETE = "deleted";        protected static final String FIELD_PUBLISHDATE = "publishdate";        protected static final String FIELD_FAVORITE = "favorite";        protected static final String FIELD_CLICKCOUNT = "clickcount";        protected static final String FIELD_FAVORITEDATE = "favoritedate";           //构造器，初始数据库服务        public DatabaseService(Context context) {            dbOpenHelper = new DatabaseHelper(context);        }           //删除表        public void dropTable(String taleName) {            dbOpenHelper.getWritableDatabase().execSQL(                    "DROP TABLE IF EXISTS " + taleName);        }        //关闭数据库        public void closeDB() {            dbOpenHelper.getWritableDatabase().close();        }        //取得数据库TBL_NAME 表的所有数据        public List> fetchALLArticle() {            SQLiteDatabase db = dbOpenHelper.getReadableDatabase();            List> list = new ArrayList>();            Cursor cur = db.query(TBL_NAME, new String[] {FIELD_ID, FIELD_TITLE, FIELD_CONTENT,                            FIELD_PUBLISHDATE,FIELD_FAVORITE ,FIELD_DELETE }, null, null, null,                            null, null);            list = getListFromDb(list, cur);            return list;        }        //取得数据库TBL_NAME表的数据个数        public long getPageCount(){            SQLiteDatabase db = dbOpenHelper.getReadableDatabase();            return DatabaseUtils.queryNumEntries(db, TBL_NAME);        }        //根据分页尺寸和页数，取得数据列表         public  List> fetchCustomArticle(long pageSize, long pageID) {            SQLiteDatabase db = dbOpenHelper.getReadableDatabase();            List> list = new ArrayList>();            String sql = "select * from " + TBL_NAME +                  " Limit "+String.valueOf((pageID-1)*pageSize)+" ,"+String.valueOf((pageID)*pageSize);            Cursor cur = db.rawQuery(sql, null);            list = getListFromDb(list, cur);            return list;        }        //取得数据列表方法        private List>  getListFromDb(List> list, Cursor cur) {            if(cur.moveToFirst()){                do{                Map map = new HashMap();                map = addValueToMap(cur);                list.add(map);                }while(cur.moveToNext());            }            return list;        }        //将数据映射到map        private Map addValueToMap(Cursor cur) {            Map map = new HashMap();            map.put("id", cur.getString(cur.getColumnIndex(FIELD_ID)));            map.put("title", cur.getString(cur.getColumnIndex(FIELD_TITLE)));            map.put("info", cur.getString(cur.getColumnIndex(FIELD_PUBLISHDATE)));            map.put("content", cur.getString(cur.getColumnIndex(FIELD_CONTENT)));            map.put("publishdate", cur.getString(cur.getColumnIndex(FIELD_PUBLISHDATE)));            map.put("favorite", cur.getString(cur.getColumnIndex(FIELD_FAVORITE)));            map.put("delete", cur.getString(cur.getColumnIndex(FIELD_DELETE)));            map.put("img", R.drawable.stop);            return map;        }       }

对该sqlite数据库单元测试的方法如下：

import android.test.AndroidTestCase;    import com.android.hanhan.util.DatabaseService;       public class DatabaseServiceTest extends AndroidTestCase{        private DatabaseService dbs;                @Override       protected void setUp() throws Exception {            dbs = new DatabaseService(getContext());        }           @Override       protected void tearDown() throws Exception {            dbs.closeDB();        }                public void testPageCount() throws Exception{            assertEquals(12, dbs.getPageCount());        }                public void testFetchALLArticle() throws Exception{            assertEquals(12, dbs.fetchALLArticle().size());        }            }

#9.我在项目中写的Database测试类也贴出来给大家看看
