使用JaCoCo 生成单测覆盖率报告

引入插件

引入 JaCoCo Plugin 的配置

<!-- JaCoCo plugin -->
<plugin><groupId>org.jacoco</groupId><artifactId>jacoco-maven-plugin</artifactId><version>0.8.7</version><configuration><includes><include>tech/**/*</include></includes></configuration><executions><execution><id>pre-test</id><goals><goal>prepare-agent</goal></goals></execution><execution><id>post-test</id><phase>test</phase><goals><goal>report</goal></goals></execution></executions>

生成报告

做好上述报告后，直接执行 mvn test 就可以生成单测覆盖率报告了。如果没有什么异常的话，程序会生成单测覆盖率报告文件，地址为： target/site/jacoco/index.html
