[FIXED] Disable TestNG for failsafe maven plugin, keep only for surefire

Issue

I have mixed unit testing frameworks (for surefire maven plugin) in a project: JUnit + TestNG (almost all tests are JUnit tests but TestNG was included by rel="nofollow noreferrer">reactive-streams TCK framework, which is required for two tests. All integration tests (failsafe) are only JUnit tests. I managed to configure surefire to run both tests: JUnit and TestNG with this plugin configuration:

    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>${surefire.version}</version>
        <dependencies>
          <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-engine</artifactId>
            <version>5.7.2</version>
          </dependency>
        </dependencies>
        <executions>
          <execution>
            <id>surefire-testng</id>
            <phase>test</phase>
            <goals>
              <goal>test</goal>
            </goals>
            <configuration>
              <skip>false</skip>
              <includes>
                <include><!-- test one --></include>
                <include><!-- test two --></include>
              </includes>
              <junitArtifactName>none:none</junitArtifactName>
            </configuration>
          </execution>
          <execution>
            <id>surefire-junit</id>
            <phase>test</phase>
            <goals>
              <goal>test</goal>
            </goals>
            <configuration>
              <skip>false</skip>
              <excludes>
                <exclude><!-- test one --></exclude>
                <exclude><!-- test two --></exclude>
              </excludes>
              <testNGArtifactName>none:none</testNGArtifactName>
            </configuration>
          </execution>
        </executions>
      </plugin>

And this config is working fine, when I run mvn test Maven run surefire tests.

But when I try to run mvn verify to check failsafe tests, Maven fails with error:

What is the correct way to disable TestNG in failsafe plugin and keep it only in surefire?

Solution

You can manually forcefully specify the provider Junit to maven-failsafe-plugin and then remove the testng from the global dependencies tag

  <plugin>
    <artifactId>maven-failsafe-plugin</artifactId>
    <configuration>
      <!-- <parallel>none</parallel> -->
      <trimStackTrace>false</trimStackTrace>
    </configuration>
    <dependencies>
      <dependency>
        <groupId>org.apache.maven.surefire</groupId>
        <artifactId>surefire-junit47</artifactId>
      </dependency>
    </dependencies>
    <executions>
      <execution>
        <goals>
          <goal>integration-test</goal>
          <goal>verify</goal>
        </goals>
      </execution>
    </executions>
  </plugin>
