将集成和单元测试报告与JaCoCo合并

Question

我正在使用maven与JaCoCo插件生成failafe和surefire报告,但我只能设法将它们放在单独的报告中.我想有一个整体覆盖视图(单元测试和集成测试之间的合并).

在我认为彻底的谷歌搜索之后,我只能找到一种方法来与Sonar一起做.有没有更简单的方法来做到这一点？

我最近实现了这个:经过一些令人头疼的事情和大量的测试后,我的配置运行得非常好.

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,您还需要配置Surefire和Failsafe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,使它符合你想要的要求.就个人而言,如果您遇到文件未被阅读的问题,我建议您查看我排除的内容并包含在surefire和failsafe中.

Answer 2

不是你想要的答案,但仍然......

在大多数情况下,您不应合并单元和集成测试的覆盖范围.

单元测试的价值在于它们改进了应用程序的设计,并确保代码的极端情况正常工作.您应该尝试对单元测试进行高分支覆盖.

集成测试的价值在于它们确保应用程序的主要用例正常工作,并确保整个堆栈正确集成.您应该尝试为集成测试提供高功能覆盖率.(但用工具测量功能覆盖率相当困难).

如果您需要集成测试来改善分支机构的覆盖范围,那么您就应该检查代码的设计.如果您在没有集成测试的情况下已经拥有较高的分支覆盖率,那么添加它们不应该显着修改您的指标

随意投票给这个答案,因为这是一个主题和相当自以为是的...

您应该查看包含merge目标的JaCoCo Maven插件的文档.
