Question

我最近尝试使用Android Instrumentation测试。因此主应用程序具有以下结构

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，告诉我已经创建了应用程序类。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时，我得到以下异常

我在做错了什么？我已经在这两天了。我的项目看起来几乎与here中找到的项目相同，但这不起作用吗？如果有人可以帮助我，我可以发送我的代码吗？提前谢谢。

com.onestopspot.api.MyApplication是我在主项目中的应用程序类。我的仪器项目似乎无法找到它？

Answer 1

尝试更改此

  <dependency>
    <groupId>com.onestopspot</groupId>
    <artifactId>api_library</artifactId>
    <version>5.0.0-SNAPSHOT</version>
    <scope>provided</scope>
    <type>apk</type>
</dependency>

<dependency>
    <groupId>com.onestopspot</groupId>
    <artifactId>api_library</artifactId>
    <version>5.0.0-SNAPSHOT</version>
    <scope>provided</scope>
    <type>jar</type>
</dependency>

到

<dependency>
    <groupId>com.onestopspot</groupId>
    <artifactId>api_library</artifactId>
    <version>5.0.0-SNAPSHOT</version>
    <scope>test</scope>
    <type>apk</type>
</dependency>

<dependency>
    <groupId>com.onestopspot</groupId>

</dependency>

Answer 2

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

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

因此，在我的项目中，当我重新命名我的仪器测试包时，一切都得到了修复。
