I am trying to incorporate a maven plugin cucumber-jvm-parallel-plugin into my Cucumber-JVM code and am running into some problems... I think I have configured my pom.xml properly, but my cucumber features are still getting ran one by one instead of in parallel.

How do I configure my pom.xml to make my cucumber features run in parallel? I have some feature files that block execution and I don't want to have to wait for them to finish in order to start testing the other features.

I followed two tutorials, and can't find where I am going wrong, or if this is expected:

Structure

Here's my program's structure:

                            └── WhenSteps.java

Maven Pom Logic

The way I configured my pom is as follows:

I copy ../../features/api/ to my build path using Maven Resources Plugin

<build>
  <resources>
     <resource>
        <directory>../../features/api/</directory> 
     </resource>
  </resources>
</build>

I tell cucumber-jvm-parallel-plugin that my features are now located at target/classes/active/, because I think ../../features/api/ was copied to target/, so target/active/ should contain my .feature files.. I think.

 <plugin>
      <groupId>com.github.temyers</groupId>
      <artifactId>cucumber-jvm-parallel-plugin</artifactId>
      ...
      <configuration>
          ...
          <featuresDirectory>${project.build.directory}/classes/active/</featuresDirectory>
          ...
      </configuration>
 </plugin>

Then, after I run maven test, all .feature files are then compiled into target/test-classes/Parallel**IT.class. One per feature file.

So I tell maven-surefire-plugin to run all <include>**/Parallel*IT.class</include> files in parallel, which are the feature files created by cucumber-jvm-parallel-plugin.

 <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <executions>
       <execution>
          <id>acceptance-test</id>
          <phase>integration-test</phase>
          <goals>
             <goal>test</goal>
          </goals>
          <configuration>
            <forkCount>5</forkCount>
            <reuseForks>true</reuseForks>
            <includes>
              <include>**/Parallel*IT.class</include>
            </includes>
          </configuration>
       </execution>
    </executions>
 </plugin>

Cucumber Runner

And my cucumber running class looks like this:

@RunWith(Cucumber.class)
@CucumberOptions(plugin={"pretty","json:../../results/api-json.json"}, glue={"com.mycompany.commonapps.queuemanager"}, features={"../../features/api/active"})
public class RunApiTest {
}

Output

When I run mvn test, I get the following:

I finally got it to work! Here's what I had to do to make my tests run in parallel:

I move some fields in the maven-surefire-plugin execution tag to the configuration tag. I moved this section:

     <forkCount>5</forkCount>
     <reuseForks>true</reuseForks>
     <includes>
        <include>**/*IT.class</include>
     </includes>

So that my maven-surefire-plugin now looks like this:

    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-surefire-plugin</artifactId>
      <version>2.19.1</version>

      <configuration>
         <forkCount>5</forkCount>
         <reuseForks>true</reuseForks>
         <includes>
             <include>**/*IT.class</include>
         </includes>
      </configuration>

    </plugin>

Since cucumber-jvm-parallel-plugin is now running the show, I had to remove my cucumber runner class. I commented it out like this:

    /*
    @RunWith(Cucumber.class)
    @CucumberOptions(plugin={"pretty","json:../../results/api-json.json"}, glue={"com.mycompany.commonapps.queuemanager"}, features={"../../features/api/active"})
    */
    public class RunApiTest {
    }

And that's it. Since Parallel**IT.class where getting created, it was maven-surefire-plugin that was not working right.
