Android项目在AVD和设备上都运行正常(还有一些bug,这就是为什么我要添加一些单元测试)
我按照这些网站的步骤(它们或多或少相同,但我仍然检查所有这些只是为了确保我做的一切正确)
http://mobile.tutsplus.com/tutorials/android/android-sdk-junit-testing/
http://developer.android.com/tools/testing/testing_eclipse.html
我使用与项目相同的工作空间创建了一个测试项目,并创建了我的第一个测试用例.当我尝试运行测试时,我得到以下内容：

这是我从LogCat得到的：

在几个论坛上搜索时,我读到这可能是由于一个糟糕的清单文件引起的,但我没有看到我的错误.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="udes.assassin.test"
android:versionCode="1"

最后,这是我唯一的JUnit类中的代码(到目前为止)
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");
}
}
谢谢
