Running single test class or group with Surefire and TestNG

Question

I want to run single test class from command line using Maven and TestNG

Things that doesn't work:

mvn -Dtest=ClassName test

I have defined groups in pom.xml, and this class isn't in one of those groups. So it got excluded on those grounds.

mvn -Dgroups=skipped-group test
mvn -Dsurefire.groups=skipped-group test

when config is

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>2.7.1</version>
  <configuration>
    <groups>functest</groups>
  </configuration>
</plugin>

Parameters work fine in there are no groups defined in pom.xml.

Similarly, when surefire is configured with

<configuration>
  <includes>
    <include>**/*UnitTest.java</include>
  </includes>
</configuration> 

I can add another test with -Dtest parameter, but cannot add group. In any combination, I can narrow down tests to be executed with groups, but not expand them.

What's wrong with my configuration? Is there a way to run a single test or group outside of those defined in pom.xml?

Tried on Ubuntu 10.04 with Maven 2.2.1, TestNG 5.14.6 and Surefire 2.7.1

Answer 1

As I've explained in question, any mention of groups either in pom.xml or on command line resulted in reduction of executed tests count. Only way I've managed to avoid this is by using mavens profiles like this:

<profiles>
    <profile>
        <id>test-slow</id>
        <build>
            <plugins>
                <plugin>
                    <artifactId>maven-surefire-plugin</artifactId>
                    <configuration>
                        <groups>slow</groups>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>

and then running tests with

mvn -P test-slow test
