Parallel Execution not happening with Cucumber JVM 4.0.0 and Junit test runner

Question

I am unable to run features in parallel using cucumber JVM 4.0.0 and Junit testrunner. I just have one browser instance opening and once the execution is completed, browser closes and opens again for next feature execution.As per my thread count of 3 in Maven surefire, i expect 3 browser instances to be opened concurrently for running 3 features. I have followed the following link, but still not successful. The Features run one after another. I have used Pico container for DI.I followed this link for updating different version of Surefire plugin but still no luck. i have tried 4.0.0 as well as 4.2.0 for IO.cucumber Jars. I have tried different versions of surefire from 2.19 to 2.22 but still no luck.I have 3 features files and each of them have one scenario outline tagged as "@Parallel".I am not sure where am going wrong.I have tried parallel as "both" and "methods" in surefire plugin. My Junit version is 4.12.

My pom is as below.

My testrunner is as below.

import org.junit.runner.RunWith;
import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;

@RunWith(Cucumber.class)
@CucumberOptions(plugin = {"html:target/cucumber-html-report",
"json:target/cucumber.json","pretty:target/cucumber-pretty.txt",
"usage:target/cucumber-usage.json, "junit:target/cucumber-results.xml"},
features={"src/test/resources/featuresfiles"},strict=false,dryRun=false,
glue={"Stepdef_new.stepdefinitions"},
tags={"@Parallel"}
}

Public class TestRunner{
}    

Answer 1

This could be irrelevant .

I tried to implement to Cucumber with Junit and because of it's limitation of being parallel on feature level and I moved to Cucumber-TestNG.

TestNG it self supports Junit. So only runner class need to changed in current design

Please have a look this once https://github.com/bhargavQA/selenium-java-cucumber-framewrok.git

This is being done with Cucumber TestNG and supports parallel execution at scenario level.

Answer 2

You can try to remove the testng dependency or to explicitly say to use the surefire-junit like

<plugins>
                    <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-surefire-plugin</artifactId>
                        <version>${surefire.version}</version>

                        <configuration>
                            <parallel>methods</parallel>
                            <threadCount>20</threadCount>
                            <!-- <useUnlimitedThreads>true</useUnlimitedThreads> -->
                            <includes>
                                <include>**/JUnitRunner.java</include>
                            </includes>
                        </configuration>


                        <dependencies>
                            <!-- https://maven.apache.org/surefire/maven-surefire-plugin/examples/junit.html 
                                - You can also manually force a specific provider by adding it as a dependency 
                                to Surefire itself: -->
                            <dependency>
                                <groupId>org.apache.maven.surefire</groupId>
                                <artifactId>surefire-junit47</artifactId>
                                <version>${surefire.version}</version>
                            </dependency>
                        </dependencies>

                    </plugin>
                </plugins>

Try this: https://github.com/rhapsodyman/cucumber4-parallel

Answer 3

I suspect you may have meant to use maven-surefire-plugin instead of maven-surefire-report-plugin in your configuration.

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.22.0</version>
            <configuration>
                <parallel>methods</parallel>
                <threadcount>3</threadcount>
            </configuration>
        </plugin>

Answer 4

You should be using maven-failsafe-plugin, not surefire. I used failsafe in combination with com.github.temyers -cucumber-jvm-parallel-plugin

Answer 5

I had the same issue (trying enabling parallel in pom but features seem to run in sequence).

While searching I found this bug https://github.com/cbeust/testng/issues/987 claiming that the parallel and threadcount configuration is ignored in maven with testng. I then realized that I had a dependency to testng while I was not using it at all (apart from some assertions that I switched to use junit).

I can see in your pom a dependency to testng. You could try remove the dependency or ensure you use one version having the testng issue fixed and try again.
