java.lang.NoClassDefFoundError: android/test/ActivityInstrumentationTestCase2
我已经创建了测试项目...我已在（运行时配置类路径 --> 用户条目 --> junit.jar 中上传了 junit.jar
当我运行代码时，出现以下错误...

您需要将其作为Android JUnit 测试运行，而不是JUnit 测试。
进入项目资源管理器中的项目->右键->Android JUnit测试
You need to run it as Android JUnit test, instead of JUnit test.
Go to the project in the project explorer->right click->Android JUnit test
android.test.ActivityInstrumentationTestCase2不在您声称已添加到类路径中的 JUnit JAR 中。这看起来像你的一个。
你编译代码了吗？如果没有，请这样做。
您是否添加了写入 .class 文件的位置的路径？如果没有，请这样做。
android.test.ActivityInstrumentationTestCase2is not in the JUnit JAR that you claim to have added to classpath.That looks like one of yours.
Did you compile the code? If not, please do so.
Did you add the path to the location where your .class files are written? If not, please do so.
请按照以下说明操作： http://developer.android.com/guide/developing/testing /testing_eclipse.html
基本上，您不必将
junit.jar添加到类路径中。Follow these instructions: http://developer.android.com/guide/developing/testing/testing_eclipse.html
Basically, you don't have to add
junit.jarto your classpath.我有类似的问题。对我来说，更改 Robotium-solo.jar 的“顺序和导出”（属性 -> 构建路径 -> 顺序和导出），即将其移动到顶部并通过右键单击项目显式选择运行为“android JUnit 测试”解决了问题。另请尝试运行提供的示例项目。
I had the similar problem. For me Changing the "Order and Export" (properties->build Path->Order and Export) of robotium-solo.jar i.e moving it to the top and explicitly selecting run as 'android JUnit test' by right clicking the project solved the problem. Also try running the sample project provided.
听起来可能很奇怪。但您需要做的就是在导入类之前导入单独的内容并且它可以工作。至少对我来说是这样。我不知道为什么我尝试这样做，但所需要的只是删除导入 com.jayway.android.robotium.solo.Solo;并将其粘贴在包装后。
It might sound strange. but all you need to do is import solo before you import the class and it works. At least it did for me. i dont know why i tried that but all it needed was to cut the import com.jayway.android.robotium.solo.Solo; and paste it just after the package.
