How can I run a single job parallely on multiple Jenkins slave?

As an experienced tutor registered on UrbanPro.com, specializing in Automation Testing Coaching, I'll guide you through the steps to efficiently run a single Jenkins job in parallel on multiple slaves, enhancing your automation testing workflow.

Running Jobs in Parallel on Jenkins Slaves

1. Prerequisites

• Jenkins Setup:
  • Ensure Jenkins is configured with multiple slave nodes to distribute the workload.
  • Install and configure necessary plugins, such as the "Parallel Test Executor Plugin."

2. Configure Jenkins Job

• Job Configuration:
  • Open the Jenkins dashboard and navigate to the job you want to run in parallel.
  • Configure the job settings as needed for your automation testing scenario.

3. Parallel Test Execution

• Parallel Plugin Integration:
  • If using the "Parallel Test Executor Plugin," configure the "Execution Method" to parallelize test execution.
  • Define the number of threads or nodes you want to use for parallel execution.

4. Node and Label Assignment

• Node Assignment:
  • In the job configuration, specify the nodes or labels where the job should run.
  • Use the "Restrict where this project can be run" option to assign nodes.

5. Distribute Test Execution

• Test Distribution:
  • If the automation tests can be split into independent units, use the "parallel" step in Jenkinsfile or job configuration.
  • Distribute the test execution logic across multiple nodes using parallel stages.

6. Resource Allocation

• Resource Configuration:
  • Adjust resource allocation based on the available nodes' capabilities.
  • Consider factors like memory, CPU, and any specific requirements for the automation tests.

7. Monitoring and Reporting

• Monitoring Progress:
  • Utilize Jenkins dashboards and build logs to monitor the progress of parallel test execution.
  • Leverage reporting tools for consolidated results and analysis.
