在开发中,为了提高开发效率,我们一般会自定义自己的工具类。为了保证项目的可靠性,在将工具类引入项目之前,我们一般都会对工具类进行单元测试,下面我们通过一个实例看一下如何搭建测试环境。
1.首先自定义一个工具类,这里我们自定义了一个连接图灵机器人API的网络测试类:
package com.yayun.chatrobot.utils;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.UnsupportedEncodingException;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLEncoder;
public class NetUtil {
private final static String URLSTRING = "http://www.tuling123.com/openapi/api";// URL
private final static String KEY = "eb5a484b007db73d44cb35300ef58c73";
private static String requestString = URLSTRING + "?key=" + KEY + "&info=";
public static String doGet(String msg) {
String result = "";
String url = "";
try {
url = requestString + URLEncoder.encode(msg, "UTF-8");
} catch (UnsupportedEncodingException e1) {
e1.printStackTrace();
}
InputStream is = null;
ByteArrayOutputStream baos = null;
try {
URL urlNet = new URL(url);
HttpURLConnection conn = (HttpURLConnection) urlNet.openConnection();
conn.setRequestMethod("GET");
conn.setReadTimeout(5000);
conn.setConnectTimeout(5000);
is = conn.getInputStream();
int len = -1;
byte[] buf = new byte[128];
baos = new ByteArrayOutputStream();
while ((len = is.read(buf)) != -1) {
baos.write(buf, 0, len);
}
baos.flush();
result = new String(baos.toByteArray());
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (baos != null) {
baos.close();
}
if (is != null) {
is.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
return result;
}
}
2.我们需要配置AndroidManifest.xml文件:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.yayun.chatrobot"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<uses-library android:name="android.test.runner" /> <!-- 单元测试 -->
<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>
</application>
<instrumentation
android:name="android.test.InstrumentationTestRunner"
android:label="This is Test"
android:targetPackage="com.yayun.chatrobot" >
</instrumentation>
</manifest>
上面配置的位置标记一下:
3.下面开始编写测试类:
import com.yayun.chatrobot.utils.NetUtil;
import android.test.AndroidTestCase;
import android.util.Log;
/**
* 继承AndroidTestCase
*
* @author Administrator
*
*/
public class TestNetUtil extends AndroidTestCase {
public void testSendInfo() {
String res = NetUtil.doGet("你好!");
Log.e("Tag", res);
res = NetUtil.doGet("你是谁!");
Log.e("Tag", res);
}
}
4.如图:选择测试方法testSendInfo,右键选择android单元测试:
运行这是报错:
原来是没有配置网络权限:<uses-permission android:name="android.permission.INTERNET"/>
配置后按照步骤4再次运行:
这时我们的测试就通过了!
