Output JUnit test report in Maven

I summarized the procedure to execute JUnit test in Maven and output the test report (HTML).

(1) Add plugin settings to pom.xml

<project ...>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.22.1</version>
        <configuration>
          <useSystemClassLoader>false</useSystemClassLoader>
        </configuration>
      </plugin>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-site-plugin</artifactId>
        <version>3.7.1</version>
      </plugin>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-report-plugin</artifactId>
        <version>2.22.1</version>
      </plugin>
    </plugins>
  </build>
  ...
</project>

The maven-surefire-plugin configuration is required to avoid problems.

There is no problem even if you do not list other plugins. (If not stated, the latest version will be used.)

(2) Execute test and generate report with mvn command

mvn clean \
    test -Dmaven.test.failure.ignore=true \
    site -DgenerateReports=false \
    surefire-report:report

The test is run and the test result report is output to target / site / surefire-report.html.

The role of each phase or goal is as follows.

clean (Phase)

Delete the build result (target).

test (Phase)

Run the test. Specify -Dmaven.test.failure.ignore = true to output the report even if there is a failed test.

site (Phase)

Originally a build life cycle for outputting the project site. Since the image and CSS linked to the report are not output only by executing surefire-report: report, execute by specifying -DgenerateReports = false and output only the image and CSS.

surefire-report:report (Goal)

Output a report (HTML) from the JUnit execution result (XML) in target / surefire-report.
