說說正常的代碼吧
1）
<span style="font-size:14px;">package com.medivh.app; public class Person { public String sub(String username) { String sub = username.substring(3); return sub; } public int add(int a,int b) { return a+b; } }</span> |
2：
<span style="font-size:14px;">package com.medivh.app; import org.junit.Test; import junit.framework.Assert; import android.test.AndroidTestCase; public class PersonTest extends AndroidTestCase { @Test public void testSub() throws Exception { Person p = new Person(); p.sub(null); } public void testAdd() throws Exception { Person p = new Person(); int result = p.add(1, 4); Assert.assertEquals(result, 6); } } </span> |
2）AndroidManifest.xml
<span style="font-size:14px;"><?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.medivh.app" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name"> <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> <span style="color:#FF0000;"><uses-library android:name="android.test.runner" /></span> </application> <uses-sdk android:minSdkVersion="8" /> <span style="color:#FF0000;"><instrumentation android:name="android.test.InstrumentationTestRunner" android:targetPackage="com.medivh.app" android:label="Tests for My App" /></span> </manifest> </span> |
3）測試
右鍵項目Run as.. Android Junit Test 就會出結果
開始的時候犯迷糊結果各種出錯：
No instrumentation runner found for the launch, using android.test.InstrumentationTestRunner
First does not specify a android.test.InstrumentationTestRunner instrumentation or does not declare uses-library android.test.runner in its AndroidManifest.xml
is not configured correctly for running tests
到網上各種查，發現配置沒錯啊。最后才發現問題出在我居然眼睛進沙子一般修改了bin下面的AndroidManifest.xml，可能是我前面打開了這個目錄，結果就隨意打開了它修改了它。希望大家以后小心行事。
