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.
