Android学习系列-单元测试与程序调试(5)
1.关键点
1)AndroidManifest.xml中必须配置如下节点
<uses-library android:name="android.test.runner" />

<instrumentation android:name="android.test.InstrumentationTestRunner"

       android:targetPackage="cn.nt.test" android:label="Test for MyApp" />


2)AndroidManifest.xml完整代码
<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
     
      package="cn.nt.test"
    
      android:versionCode="1"

      android:versionName="1.0">

    <application android:icon="@drawable/icon" android:label="@string/app_name">

        <activity android:name=".MainActivity"

                  android:label="@string/app_name">

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

 

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

    </application>

    <uses-sdk android:minSdkVersion="8" />

   <instrumentation android:name="android.test.InstrumentationTestRunner"

       android:targetPackage="cn.nt.test" android:label="Test for MyApp" />


</manifest>
3)单元测试类必须继承自AndroidTestCase
例如:public class LogTest extends AndroidTestCase{
                   public void testSave() throws Exception{
                             PersonService service = new PersonService();
                            service.save(null);
                    }

                  public void testAdd() throws Exception{
                          PersonService service = new PersonService();
                           int actual = service.add(1, 2);
                          Assert.assertEquals(8, actual);//测试结果会在单元测试窗口中显示
      }


 }

2.程序调试输出信息
        private static final String TAG = "LogTest";
 
 public void testOutLog() throws Throwable{
  Log.i(TAG, "www.baidu.cn");
 }
 
 public void testOutLog5() throws Throwable{
  Log.i(TAG, "123456");
 }
 
 public void testOutLog2() throws Throwable{
  System.out.println("www.csdn.com");
 }
 
 public void testOutLog3() throws Throwable{
  System.err.println("www.163.com");
 }
输出信息在Logcat窗口中能够看到。
信息分类级别debug<info<warn<error.
