Parallel Execution with maven-failsafe-plugin query

[Vikram]

Hi All,

I'm trying to achieve parallel execution with help of maven-failsafe-plugin but I'm not understanding how to control number of browsers getting launched.  

With below setup the number of browser getting launched varies each time. I have 5 java classes each one having different number of JUnit test cases

I read  https://maven.apache.org/surefire/maven-failsafe-plugin/examples/fork-options-and-parallel-execution.html but couldn't find the expected solution.

<groupId>org.apache.maven.plugins</groupId>

                <artifactId>maven-failsafe-plugin</artifactId> <!-- http://maven.apache.org/surefire/maven-failsafe-plugin/ -->

                <version>2.18.1</version>

                <configuration>

                    <includes>

                        <include>**/*Test.java</include>

                    </includes>

                   <parallel>methods</parallel>

                  <threadCountMethods>1</threadCountMethods>

I tried googling but couldn't find answer yet.

Thanks in advance.

Regards,

Vikram

https://maven.apache.org/surefire/maven-failsafe-plugin/examples/junit.html#Running_tests_in_parallel also mentions specifying thread-count.  If you do not want the number of parallel tests to exceed say 5 , then set thread-count to 5.

To do it in jUnit you will need to write a custom test runner.  Using the maven-failsafe-plugin on it's own will result in lots of browsers opening but they won't be reused properly.

It's generally easier to do it in TestNG, this may help if you decide to go down that route:

Hi Mark,

Thanks for reply , can you please give any example with Junit and custom test runner. ( because of framework related issue I can't switch to TestNG )

@ Niharika, thanks for reply as well. But I'm facing exactly same problem which Mark has mentioned.  I'm looking for solution involving JUnit itself.

     Please let me know if you have implemented it successfully.

Best Regards,

Vikram

Hi Mark , Niharika,

Just to update on this thread , I could able to get parallel execution with below change in pom.xml

maven-surefire-plugin

<parallel>classes</parallel>

<threadCount>1</threadCount>

With this setup for each java file one browser will be launched.

But problem with this approach is there are test cases failures which won't happen with single m/c + single browser approach.

For now I have kept aside parallel approach and look for Grid to speed up automation execution.

Thanks,

Vikram
