Executing Cucumber Feature Files in Parallel

To execute Cucumber feature files in parallel, you can leverage a plugin called cucumber-jvm-parallel-plugin. Here's how to use it:

1. Add the Plugin to Your POM:

   <code class="xml"><dependency>
     <groupId>com.github.temyers</groupId>
     <artifactId>cucumber-jvm-parallel-plugin</artifactId>
     <version>2.1.0</version>
   </dependency></code>

2. Configure the Plugin in Your Build:

   <code class="xml"><plugin>
     <groupId>com.github.temyers</groupId>
     <artifactId>cucumber-jvm-parallel-plugin</artifactId>
     <version>2.1.0</version>
     <executions>
       <execution>
         <id>generateRunners</id>
         <phase>generate-test-sources</phase>
         <goals>
           <goal>generateRunners</goal>
         </goals>
         <configuration>
           <!-- Package names for glue code -->
           <glue>com.example.cucumber</glue>
           <!-- Output directory for generated runner classes -->
           <outputDirectory>${project.build.directory}/generated-test-sources/cucumber</outputDirectory>
           <!-- Features directory -->
           <featuresDirectory>src/test/resources/features/</featuresDirectory>
           <!-- Output directory for Cucumber reports -->
           <cucumberOutputDir>target/cucumber-parallel</cucumberOutputDir>
           <!-- Output format -->
           <format>json</format>
           <!-- Strict property -->
           <strict>true</strict>
           <!-- Monochrome property -->
           <monochrome>true</monochrome>
           <!-- Tags to run -->
           <tags></tags>
           <!-- Filter features by tags -->
           <filterFeaturesByTags>false</filterFeaturesByTags>
           <!-- Use TestNG runners -->
           <useTestNG>false</useTestNG>
           <!-- Naming scheme -->
           <namingScheme>simple</namingScheme>
           <!-- Naming pattern -->
           <namingPattern>Parallel{c}IT</namingPattern>
           <!-- Parallel scheme -->
           <parallelScheme>SCENARIO</parallelScheme>
         </configuration>
       </execution>
     </executions>
   </plugin></code>

3. Configure Surefire Plugin to Invoke TestNG Runners:

   <code class="xml"><plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-surefire-plugin</artifactId>
     <version>2.19</version>
     <configuration>
       <forkCount>5</forkCount>
       <reuseForks>true</reuseForks>
       <includes>
         <include>**/*IT.class</include>
       </includes>
     </configuration>
   </plugin></code>

4. Share the WebDriver Instance:
   In order to avoid having different thread instances of the WebDriver, you must implement a shared WebDriver class that prevents the driver.quit() method from being called:

   <code class="java">import org.openqa.selenium.WebDriver;
   import org.openqa.selenium.firefox.FirefoxDriver;
   import org.openqa.selenium.support.events.EventFiringWebDriver;
   
   public class SharedDriver extends EventFiringWebDriver {
     private static WebDriver REAL_DRIVER = null;
   
     public SharedDriver() {
       super(CreateDriver());
     }
   
     public static WebDriver CreateDriver() {
       WebDriver webDriver;
       if (REAL_DRIVER == null) {
         webDriver = new FirefoxDriver();
         setWebDriver(webDriver);
       }
       return webDriver;
     }
   
     public static void setWebDriver(WebDriver webDriver) {
       REAL_DRIVER = webDriver;
     }
   
     public static WebDriver getWebDriver() {
       return REAL_DRIVER;
     }
   
     @Override
     public void close() {
       if (Thread.currentThread() != CLOSE_THREAD) {
         throw new UnsupportedOperationException("You shouldn't close this WebDriver. It's shared and will close when the JVM exits.");
       }
       super.close();
     }
   }</code>

5. Configure Hub to Support Parallel Execution:
   If you plan on running more than 50 threads, you need to increase the -DPOOL_MAX value for the Hub.

   java -jar selenium-server-standalone-<version>.jar -role hub -DPOOL_MAX=512

6. Execute the Feature Files:
   Run your Cucumber tests in parallel using the command:

   mvn test
