Question

我尝试使用代码覆盖率运行android单元测试。我正在使用Android示例NotePad。

这些是我使用的命令：

cd <main project folder>
android update project --path .
android update test-project -m <full path to main project> -p <full path to main project>\tests
cd ./tests
ant emma debug install test

测试成功运行。但最终艾玛无法生成报告html文件。

在这里，您将获得ant emma debug install test的命令行输出

我想发布C：\ Android \ android-sdk \ tools \ ant \ build.xml但文件很长。但我想它总是一样的......

有什么想法吗？

Answer 1

命令ant emma debug install test仅在root设备或模拟器上成功（否则权限被拒绝）。

有用的提示：

如果您使用的是SDK 13或更早版本，则可以使用 ant coverage 代替 ant emma调试安装测试
最后一个输出行显示报告文件的保存位置
如果您使用Windows，则必须添加android.bat的路径（通常为/ tools）和ant.bat的路径（取决于您安装Ant的位置;如果您将Eclipse与ADT一起使用，则通常存在：/插件/ org.apache.ant ... / bin）到PATH变量（您可能还需要使用不同的操作系统）

ant emma BUILD FAILED
