因此，我在Eclipse中使用EclEmma来生成XML覆盖率报告。看起来像这样：

在此文件中，它显示了一个测试“ mainTest”，我想知道的是“ mainTest”文件涵盖了哪些文件，以及“ mainTest”测试所覆盖的文件中有多少％。如果ECLEmma不起作用，欢迎提供其他可以达到此目的的工具的提示：)
最佳答案
您可以使用“ includes”参数来指定要在报告中使用的类。请参阅此处的文档：
https://www.eclemma.org/jacoco/trunk/doc/report-mojo.html
还有许多其他代码覆盖工具可用，选择要包含的测试将是一个常见的选择。此处提供示例列表：
