To generate the Surefire report as part of the site generation, add the following in the <reporting> section of your POM:
<project> ... <reporting> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-report-plugin</artifactId> <version>2.22.0</version> </plugin> </plugins> </reporting> ... </project>
When mvn site is invoked, the report will automatically be included in the Project Reports menu as shown in the figure below.
