我最近一直在尝试使用 Android Instrumentation 测试。所以主应用程序有以下结构

现在在我的主项目中，在 com.onestopspot.api 下我有我的 android 应用程序类。在 onCreate 函数中，我有一条简单的 log.d 消息，告诉我应用程序类已创建。现在在我的测试项目中，我有一个 com.onestopspot.api 我有以下类

package com.onestopspot.api;

import junit.framework.Test;
import junit.framework.TestSuite;

import android.test.InstrumentationTestRunner;
import android.test.suitebuilder.TestSuiteBuilder;

public class AllTests extends TestSuite {

    public static Test suite() {
        return new TestSuiteBuilder(AllTests.class)
                .includeAllPackagesUnderHere()
                .build();
    }
}

现在当我说 mvn clean install 我得到以下异常

我做错了什么？我已经在这两天了。我的项目看起来几乎与此处here 的项目相同，但这行得通吗？如果有人可以帮助我，我可以发送我的代码吗？提前致谢。

com.onestopspot.api.MyApplication 是我在主项目中的应用程序类。我的仪器项目似乎找不到它？

【问题讨论】：

看看logcat，它是否提供了任何额外的信息？
没有。只是我提供的错误。我可以给您发送示例项目吗？它非常小，只有 2 个班级？
我这里没有任何设置或设备来运行您的项目，所以很遗憾，发送它并没有多大用处。您是否尝试过将项目缩减到最低限度？
这是最低限度的。一个应用程序类，一个主项目中的活动。和一个应用仪表类。我已经在我的问题中编辑了 logcat 异常。
看看答案here有没有帮助。

我也遇到了同样的问题。事实证明，我的应用程序和我的测试项目具有相同的包名（在清单文件中）。 Adb 通过那里的包名称卸载并安装 apk。这组指令是在执行测试之前由 adb 执行的：

卸载应用
安装应用程序
卸载测试（如果它们与应用具有相同的包名，这将卸载您的应用！！）
安装测试
运行测试

因此，在我的项目中，当我重命名我的仪器测试包时，一切都已修复。
