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"
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

我有一个项目和一个项目测试.我的项目清单：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.toto.app"
  android:versionCode="3"
  android:versionName="0.3.1">
  ...
    <application android:icon="@drawable/icon" android:label="@string/app_name">
    ...
    </application>
</manifest>

我的测试项目显示：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.toto.app.test"
  android:versionCode="1"
  android:versionName="1.0">
  <uses-sdk android:minSdkVersion="4" />

  <instrumentation android:targetPackage="com.toto.app" android:name="android.test.InstrumentationTestRunner" />

  <application android:icon="@drawable/icon" android:label="@string/app_name">
    <uses-library android:name="android.test.runner" />
  </application>
</manifest>

这是我要测试的活动：src / com / toto / app / activity / ListActivity,我有一个启动此活动的LaunchActivity(在清单中声明为启动活动).

在测试中,我的ListActivityTest位于相同的路径中(src / com / toto / app / activity).我也试过src / com / toto / app / test.来源是：

public class ListActivityTest extends  ActivityInstrumentationTestCase2<LaunchActivity>{

  private Solo solo;

  public ListActivitytest() {
    super(LaunchActivity.class);
  }

  public void setUp() throws Exception {
    solo = new Solo(getInstrumentation(),getActivity());
    solo.wait(2000);
  } 
}

似乎找到了LaunchActivity但是当它启动ListActivity时,我得到了错误：

% adb shell am instrument -w com.toto.app.test/android.test.InstrumentationTestRunner

com.toto.app.activity.ListActivityTest:INSTRUMENTATION_RESULT: shortMsg=java.lang.classNotFoundException
INSTRUMENTATION_RESULT: longMsg=java.lang.classNotFoundException: com.toto.app.activity.ListActivity in loader dalvik.system.PathClassLoader[/system/framework/android.test.runner.jar:/data/app/com.toto.app.test-2.apk:/data/app/com.toto.app-2.apk]

我不明白为什么找到一个类而另一个不是……它在Eclipse中以同样的方式失败.我试图在测试用例中直接使用ListActivity但是同样的错误.它如何构建这个apk以避免某些类？

这是使用adb时的完整堆栈.

要解决这个问题,我必须在主项目中导出android-support-v4.jar.

希望能帮助别人……
