How do you set up parallel testing in a Jenkins pipeline?
Running tests in parallel can significantly speed up Jenkins build times. This question focuses on configuring a Jenkins pipeline to execute test suites in parallel, reducing total testing duration. Example Jenkinsfile snippets can show the setup for parallel stages, enabling efficient use of resources and faster feedback.

Running tests in parallel can vastly cut down on build times. In Jenkins, you can set up pipeline stages to run in parallel using the parallel directive. The value of parallel stages is especially great when you're running multiple types of tests, such as unit and integration tests, which don't depend on one another.
For instance:
Unit Tests: Run core functionality tests
Integration Tests: Test interactions with databases and services
Load Tests: Test performance under simulated load.
This has the advantage of quick feedback as well as far more effective use of resources, especially in bigger codebases.

Use parallel stages in Jenkins to run tests simultaneously, reducing overall build time.

Example:

This example splits tests into separate, parallel stages.
