用JaCoCo合并集成和单元测试报告

Question

在我认为是彻底的谷歌搜索后，我只能找到一种方法来做这件事与声纳。有没有更简单的方法可以做到这一点？

Answer 1

我最近实现了这一点：在经历了一些头痛和大量测试后，我有了一个运行良好的配置。

如您所见，有6个不同的Jacoco执行来运行测试、合并文件并创建聚合报告。在Jacoco配置之上，还需要配置Surefire和Failsafe以从Jacoco获取参数（Surefire运行单元测试，Failsafe运行集成测试）。

我使用的所有配置都应该在那里，你用它做的是你的设计架构，使它适合你想要的需求。就我个人而言，如果您遇到文件未被读取的问题，我建议查看一下我在surefire和failsafe中排除和包括的内容。
