Question

首先是设置：我们在tomcat上将一个应用程序部署为带有几个Servlet的war文件，然后在jacoco代理处于活动状态时启动。我们运行的测试是集成测试，jacoco-it.exec文件是在tomcat shutdown上创建的，甚至包含数据。但是，即使我们的测试触及所有Servlet，只有一个类显示为“覆盖”，这是枚举的私有构造函数（由枚举以静态方式调用）。

更新inbetween：我现在注意到，“sessions”部分显示了所涵盖的所有类，它包含了所提到的枚举以及测试类，这是奇怪的，因为它们不应该被包含在内（它们没有戴上tomcat）。枚举也用于测试，这将解释它的涵盖

我在之前的项目中使用jacoco-integration-test-coverage完成了相同的程序，这一切都很好，所以我不知道是什么问题。

我尝试添加includeBootstrapClasses属性和其他一些调整（将dumpOnExit设置为true / false等），但没有一个工作。我甚至尝试过离线仪器，这只会产生相同的结果。将static {}块添加到servlet的代码中，只是将“foo”打印到控制台也不会被标记为已覆盖，即使tomcat-log包含消息。

Jacoco config in pom：

                    </execution>
                </executions>
            </plugin>

failsafeArgLine（在config中使用）如下： -javaagent:/home/jenkins/.m2/repository/org/jacoco/org.jacoco.agent/0.7.2.201409121644/org.jacoco.agent-0.7.2.201409121644-runtime.jar=destfile=/home/jenkins/jenkins/jobs/dms-coverage/workspace/com.example.dms/target/jacoco-it.exec

surefireArgLine并不重要，因为现在没有单元测试，只有集成测试。

请注意，jacoco可以检测东西，但不是tomcat上的类，而是测试类。

如果您有任何想法，这里有什么问题，请给我一个提示。

谢谢和问候，凯

JaCoCo测试文件而不是实际来源
