Simple tutorial for Android-50th gun (Tool Test) and android Tool

In development, we generally customize our own tool classes to improve development efficiency. To ensure the reliability of the project, we usually perform unit tests on the tool class before introducing the tool class to the project. Let's take an example to see how to build a test environment.

1. First, define a tool class. Here we have customized a network test class that connects to the Turing robot API:

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";// URLprivate 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. We need to configure the AndroidManifest. xml file:

<? 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. t Est. runner "/> <! -- Unit test --> <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>

Mark the position configured above:

3. Write the test class as follows:

Import com. yayun. chatrobot. utils. netUtil; import android. test. androidTestCase; import android. util. log;/*** inherits AndroidTestCase ** @ author Administrator **/public class TestNetUtil extends AndroidTestCase {public void testSendInfo () {String res = NetUtil. doGet ("Hello! "); Log. e (" Tag ", res); res = NetUtil. doGet (" who are you! "); Log. e (" Tag ", res );}}

4. Right-click testSendInfo and choose android unit test:

This is an error:

Originally, no network permission was configured: <uses-permission android: name = "android. permission. INTERNET"/>

After configuration, follow Step 4 to run again:

Now our test is passed!
