在我的项目中，我使用 Jacoco 插件来显示单元测试和集成测试的覆盖率报告，以及一份显示组合代码覆盖率的报告。现在我想为组合覆盖率设置覆盖率，但我的构建现在失败了，因为 Jacoco 只有寻找单元代码覆盖率，不合并，当然比指定的合并报告小。
我在 pom.xml 中遗漏了什么吗？
这是我在 pom.xml 中关于覆盖率的配置:
<execution>
<id>default-check</id>
<goals>
<goal>check</goal>
</goals>
<configuration>
<rules>
<rule>
<element>BUNDLE</element>
<limits>
<limit>
<counter>LINE</counter>
<value>COVEREDRATIO</value>
<minimum>0.80</minimum>
</limit>
</limits>
</rule>
</rules>
</configuration>
</execution>
最佳答案
编辑:也许更好的方法是使用相同的文件，但让它附加另一个对我们有用的测试 - 单元和它测试。

原文:我受到了 another post 和 in this blog 的启发，产生了以下代码，其中可见，即测量单元测试、集成测试的覆盖率，然后合并结果并且仅对于整个包(不是单个类)它失败，如果覆盖率是低于 70%。

关于java - 单元测试和集成测试的 Jacoco 覆盖率与覆盖率相结合，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/52234447/
