Parallel Test Execution Jenkins

Question

I have some automated tests that I'm running using Jenkins.

I've Jenkins connected to my GitSwarm which pulls the code from my branch and then exectutes it.

I have installed the "Parallel Test Job Execution Plugin" for Jenkins.

In the plugin I have specified the tests to run in 3 batches

Is there anything else I should specify? I didn't think I would have to since I'm connecting to GitSwarm to run the code. The console output seems to state otherwise !

Any help would be greatly appreciated, it does seem like an easy way to have tests running parallel so hopefully its only a small error.

Answer 1

I think you have misunderstood the plugin:

This plugin adds a new builder that lets you easily execute tests defined in a separate job in parallel. This is achieved by having Jenkins look at the test execution time of the last run, split tests into multiple units of roughly equal size, then execute them in parallel.

You have do define a new job to run the tests which is called by this plugin. ( source )

But I want to ...

You can achieve this on different ways:

• Use the parallel keyword of TestNG
  You can define test suites and say how they should be executed.
• Create a new job which takes the test to run as parameter and call it via the plugin (You need a new job and have the overhead of Jenkins)
• Use the parallel keyword of the Job DSL Plugin or Pipeline Plugin (You have to recreate the job definition)
