为什么 Jacoco 的集成测试覆盖率为 0%

Question

我已经设置了 Maven 项目，以便在我的 it 配置文件中获取集成测试覆盖率。但是 jacoco 报告显示所有类的值为 0%。

我在配置文件和故障安全插件中的主要 POM Jacoco 集成设置部分：

执行命令的 api 测试模块 POM 的配置文件设置

<profile>
    <id>it</id>
    <properties>
        <skip.it.tests>false</skip.it.tests>
        <spring.profile>it</spring.profile>
        <skipTests>true</skipTests>  -- This is for unit tests
    </properties>
</profile>

但是我可以看到 jacoco-it.exec 文件已经生成，报告文件如下。

版本：

<jacoco.plugin.version>0.8.3</jacoco.plugin.version>
<maven-failsafe-plugin.version>3.0.0-M5</maven-failsafe-plugin.version>

执行测试的命令：mvn clean verify -P it。这将启动服务器并在那里运行所有集成测试（api 端点测试）。

进一步设置单元测试时，surefire plugin 按预期工作，并在 jacoco 报告中显示适当的覆盖范围。
