Create an android project and create a Test. java file. Be sure to inherit AndroidTestCase by defining a class inheritance.

package com.wuyudong.juint.test;import com.wuyudong.juint.util.Utils;import android.test.AndroidTestCase;public class Test extends AndroidTestCase {        public void test() {        int res = Utils.add(3, 5);        assertEquals(8, res);    }}

Create the Toolkit file Utils. java

package com.wuyudong.juint.util;public class Utils {    public static int add(int a, int b) {        return a - b;    }}

Run the project and report the following error:

[06:21:13-unit test] unit test does not specify a android. test. InstrumentationTestRunner instrumentation or does not declare uses-library android. test. runner in its AndroidManifest. xml

Add the following code to AndroidManifest. xml:

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.wuyudong.juint"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="8"        android:targetSdkVersion="17" />        <instrumentation         android:name="android.test.InstrumentationTestRunner"        android:targetPackage="com.wuyudong.juint"        ></instrumentation>    <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.wuyudong.juint.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></manifest>

Continue to run unit test. The following asserted exception occurs.
