android单元测试----junit

在项目的AndroidManifest.xml功能清单文件中加入如下类库代码：

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="cn.itcast.test"

android:versionCode="1"

android:versionName="1.0">

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

<activity android:name=".MainActivity"

android:label="@string/app_name">

<intent-filter>

</intent-filter>

</activity>

</application>

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

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

android:targetPackage="cn.itcast.test" android:label="Tests for My App" />

</manifest>

被测试方法：

public class PersonService {

public int save() {

String in = "78";

int b = new Integer(in);

return b;

}

单元测试类：必须继承AndroidTestCase

public class PersonServiceTest extends AndroidTestCase {

private static final String TAG = "PersonServiceTest";

public void testSave() throws Throwable{

PersonService service = new PersonService();

int b = service.save();//检验save()方法运行是否正常

//Log.i(TAG, "result="+ b);

//System.out.println();

//System.err.println("result="+ b);

Assert.assertEquals(78, b);

}
