本文详细介绍了如何在Android环境中搭建单元测试环境，并通过代码实例展示了如何对数据库中的业务类进行测试，包括创建数据库、插入数据、更新数据、删除数据和查找数据的操作。

单元测试环境搭建：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.db.demo"
      android:versionCode="1"
      android:versionName="1.0">
    <uses-sdk android:minSdkVersion="8" />
    <instrumentation android:targetPackage="com.db.demo" 
    	android:name="android.test.InstrumentationTestRunner" />

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".DBActivity"
                  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>
</manifest>

对上篇文章的数据库中的业务类进行测试：

package com.db.demo;

import java.util.List;

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

public class PersonServiceTest extends AndroidTestCase {
	public void testCreateDB() throws Throwable {
		DBOpenHelper dbOpenHelper = new DBOpenHelper(this.getContext());
		dbOpenHelper.getWritableDatabase();
	}

	public void testInsert() throws Throwable {
		PersonService ps = new PersonService(this.getContext());
		Person p = new Person();
		
		p.setName("abc");
		ps.insert(p);
		
		p = new Person();
		p.setName("def");
		ps.insert(p);
		
		p = new Person();
		p.setName("ghi");
		ps.insert(p);
		
		p = new Person();
		p.setName("dd");
		ps.insert(p);
		
		p = new Person();
		p.setName("ff");
		ps.insert(p);
		
		p = new Person();
		p.setName("ee");
		ps.insert(p);
		
		p = new Person();
		p.setName("ww");
		ps.insert(p);
		
		p = new Person();
		p.setName("hh");
		ps.insert(p);
		
		p = new Person();
		p.setName("jj");
		ps.insert(p);
		
		p = new Person();
		p.setName("uu");
		ps.insert(p);
	}

	public void testUpdate() throws Throwable {
		PersonService ps = new PersonService(this.getContext());
		Person p = new Person();
		ps.update(p);
	}

	public void testDelete() throws Throwable {
		PersonService ps = new PersonService(this.getContext());
		ps.delete(1);
	}

	public void testFind() throws Throwable {
		PersonService ps = new PersonService(this.getContext());
		Person p = ps.find(1);
		Log.d(AppConstant.TAG, p.toString());
	}
	
	public void testGetScrollData() throws Throwable {
		PersonService ps = new PersonService(this.getContext());
		List<Person> persons = ps.getScrollData(0, 3);
		for(Person person : persons) {
			Log.d(AppConstant.TAG, person.toString());
		}
	}

	public void testGetCount() throws Throwable {
		PersonService ps = new PersonService(this.getContext());
		Log.d(AppConstant.TAG, ps.getCount() + "");
	}
}
