Android單元測試jUnit

慕課網的智能機器人的那個項目視頻中學到的。

    寫了一個工具類(HttpUtils)，可以寫一個單元測試去測試其類的功能是否正確，而不必等佈局文件寫好再去測試。

    貼代碼一:HttpUtils工具類

public class HttpUtils {
    private static final String URL="http://www.tuling123.com/openapi/api";
    private static final String API_KEY="950e94cd5cf0a9de9a66d68a6c240502";
    public static String doGet(String msg){
    	String result ="";
    	String url =setParams(msg);
    	Log.i("TAG","zzj--url地址-->>"+url);
    	InputStream is=null;
    	ByteArrayOutputStream baos=null;
    	
    	try {
			java.net.URL urlNet = new java.net.URL(url);
			HttpURLConnection conn =(HttpURLConnection)urlNet.openConnection();
			conn.setReadTimeout(5000);
			conn.setConnectTimeout(5000);
			conn.setRequestMethod("GET");
			
			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);
			}
			
			result = new String(baos.toByteArray());
			baos.flush();
			Log.i("TAG","-HTTP-1>>"+result);
		} catch (MalformedURLException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}finally{
			if(baos!=null){
				try {
					baos.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
			if(is!=null){
				try {
					is.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
    	Log.i("TAG","-HTTP->2>"+result);
    	return result;
    }
	private static String setParams(String msg) {
		String url="";
		try {
		url=URL+"?key="+API_KEY+"&info="+URLEncoder.encode(msg,"UTF-8");
		} catch (UnsupportedEncodingException e) {
			e.printStackTrace();
		}
		return url;
	}
}

貼代碼二: 要在AndroidManifest.xml中寫兩個標籤<uses-library />  <instrumentation />

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.robot"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="15"
        android:targetSdkVersion="19" />
    <uses-permission android:name="android.permission.INTERNET"/>
    <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"/>
        <activity
            android:name="com.example.robot.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:targetPackage="com.example.robot"
                     android:label="this is a test"
                     android:name="android.test.InstrumentationTestRunner"></instrumentation>
</manifest>

貼代碼三: 寫一個類extends AndroidTestCase

public class TestHttpUtils extends AndroidTestCase {
    public void testSendInfo(){
    	String res =HttpUtils.doGet("給我講個笑話");
    	Log.i("TAG","z-笑話->>"+res);
    	res = HttpUtils.doGet("給我講個鬼故事");
    	Log.i("TAG","z-故事->>"+res);
    	  	
    }
}

使用方法: 鼠標選中testSendInfo()方法的位置，右鍵 run as -> Android jUnit Test
