安卓的JUnit测试ClassNotFoundException的 [英] Android JUnit testing ClassNotFoundException
问题描述
我试图安装的JUnit测试我的活动，为的Android项目。
I'm trying to setup JUnit to test my activities for an android project.
在Android项目（还剩下还有一些错误，这就是为什么我要添加一些单元测试）运行OK双方的AVD和设备
The Android Project runs ok on both an AVD and a device (there are still a few bugs left, which is why I want to add a few unit tests)
我跟着从这些网站中的步骤（他们都或多或少相同的，但我还是检查所有的人都只是为了确保我正确地做了一切）
<一href="http://mobile.tutsplus.com/tutorials/android/android-sdk-junit-testing/">http://mobile.tutsplus.com/tutorials/android/android-sdk-junit-testing/
<一href="http://developer.android.com/tools/testing/testing_eclipse.html">http://developer.android.com/tools/testing/testing_eclipse.html
I followed the steps from these websites (they are more or less the same, but I still checked all of them just to make sure I did everything correctly)
http://mobile.tutsplus.com/tutorials/android/android-sdk-junit-testing/
http://developer.android.com/tools/testing/testing_eclipse.html
我创建使用相同的工作空间作为我的项目的测试项目，并建立了我的第一个测试用例。当我试图运行测试，我得到了以下内容：
I created a test project using the same workspace as my project, and created my first test case. When I tried to run the test, I got the following:

在搜索上的几个论坛，我读了这可能是由坏的清单文件造成的，但我看不出有什么不对我的
While searching on a few forums, I read that this might be caused by a bad manifest file, but I don't see what is wrong with mine
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="udes.assassin.test"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="10" />
<instrumentation
android:name="android.test.InstrumentationTestRunner"
android:targetPackage="udes.assassin" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<uses-library android:name="android.test.runner" />
</application>
</manifest>
最后，这是code。在我唯一的JUnit类（到目前为止）
And finally, this is the code in my only JUnit class (so far)
package udes.assassin.test;
import static org.junit.Assert.*;
import org.junit.Before;
import org.junit.Test;
import udes.assassin.InGameActivity;
import android.test.ActivityInstrumentationTestCase2;
public class InGameActivityTest
extends ActivityInstrumentationTestCase2<InGameActivity> {
public InGameActivityTest() {
super("udes.assassin", InGameActivity.class);
}
public InGameActivityTest(Class<InGameActivity> activityClass) {
super(activityClass);
}
@Before
protected void setUp() throws Exception {
super.setUp();
}
@Test
public void testSetItemPosition() {
fail("Not yet implemented");
}
}
感谢您
推荐答案
这可能是因为JUnit是不是在你的类路径中。转到项目 - ＆GT;属性 - ＆GT; Java构建路径 - ＆GT;订单和出口，并检查了JUnit选中该复选框。
It is probably because JUnit is not in your classpath. Go to Project -> Properties -> Java Build Path -> Order and Export and check if the JUnit box is unchecked.
