本文介绍了一个简单的Android应用程序如何使用内置的日志记录功能，并通过一个具体的单元测试案例展示了如何进行基本的功能验证。

日志输入

LogActivity

package org.wp.activity;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;

/**
 * 
 * 调整日志输出的级别 
 * Eclipse ==> Window ==> Preferences ==> Android ==> DDMS ==> Logging Level
 * 日志输入 
 * Eclipse ==> Window ==> Show View ==> Other ==> Android ==> LogCat
 * 
 * @author wp
 * 
 */

public class LogActivity extends Activity {
	private static final String TAG = "LogActivity"; // 快捷键ctrl+shift+x

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		Log.i(TAG, "LogActivity Created");
	}
}

单元测试(Debug)

LogTest

package org.wp.activity;

import android.test.AndroidTestCase;
import android.util.Log;

/**
 * JunitRun ==> LogTest(实例化) ==> testSave() 
 * Debug 
 * Step Into F5 
 * Step Over F6 
 * Run to Line Ctrl + R 
 * Step Return F7
 * 
 * @author wp
 * 
 */

public class LogTest extends AndroidTestCase {

	private static final String TAG = "LogTest";

	public void testSave() throws Exception {
		int i = 1 + 1;
		String result = practice(i);
		Log.i(TAG, "result=" + i);
		Log.i(TAG, "result=" + result);
	}

	private String practice(int i) {
		int a = i;
		int b = 100;
		int c = a + b;
		String out = "wp";
		String result = out + c;
		return result;
	}
}

AndroidManifest.xml
