java - EclEmma for Eclipse 可以通过测试显示代码覆盖率吗？

Question

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

<?xml version="1.0" encoding="UTF-8" standalone="true"?>

在此文件中，它显示了一个测试“mainTest”我想知道的是女巫文件“mainTest”覆盖以及测试“mainTest”覆盖的这些文件的百分比。如果 ECLemma 不起作用，欢迎提供其他可以实现此目的的工具的提示:)

您可以使用“includes”参数来指定报告中需要哪些类。请参阅此处的文档:

https://www.eclemma.org/jacoco/trunk/doc/report-mojo.html

还有许多其他可用的代码覆盖工具，选择您想要包含的测试将是一个常见的选择。此处提供示例列表:
