Jacoco Maven离线仪器-Tomcat

jacoco-maven-plugin jacoco integration-testing tomcat java

我正在尝试获取集成测试的代码覆盖率报告。Jacoco maven插件能够为单元测试提供代码覆盖率,但为集成测试提供0%的覆盖率。集成测试正在触及应用程序的RESTAPI端点,该应用程序已部署在tomcat中。

我得到的最新错误是“由于缺少执行数据文件,跳过JaCoCo执行。”

引用 documentation of prepare-agent-integration

与prepare agent相同,但提供了适用于集成测试的默认值:

绑定到预集成测试阶段

不同的目标文件

引用 documentation of prepare-agent :

作为VM参数传递给被测应用程序 . 默认情况下,根据项目打包类型,将设置具有以下名称的属性:

第谷。用于封装类型eclipse测试插件的testArgLine和

在大多数情况下 argLine 由自动选取 maven-surefire-plugin 这将启动JVM来执行单元测试- http://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html#argLine

argLine:在命令行上设置的任意JVM选项。

这就解释了为什么您要获得单元测试的覆盖率。

为了获得集成测试的覆盖率,您必须确保将此属性传递给被测试应用程序的JVM,即执行Tomcat的JVM,这完全取决于您启动它的方式。

在叶夫根尼的帮助下,我完成了这项工作。将服务器更改为glassfish&ide到intellij以便于调试。
