testland/jenkinsfile-test-stages
Use for any question or task about running tests in Jenkins, including quick ones such as running tests in parallel or publishing JUnit results when tests fail: declarative Jenkinsfile test stages, parallel stages across agents, post always/failure actions, JUnit report publishing and lockable resources for shared test infrastructure.

Jenkins - parallel and matrix stages
Deeper recipes split out of jenkinsfile-test-stages SKILL.md:
running stages concurrently, and fanning a stage across an
OS × runtime matrix.
Parallel stages
pipeline {
agent any
stages {
stage('Tests') {
parallel {
stage('Unit') {
steps { sh 'npm test' }
}
stage('Integration') {
steps { sh 'npm run test:integration' }
}
stage('E2E') {
agent {
docker { image 'mcr.microsoft.com/playwright:v1.50.0-noble' }
}
steps { sh 'npx playwright test' }
}
}
}
}
}Parallel stages can have different agents - useful when E2E needs a Playwright-equipped image.
Matrix builds (Jenkins 2.302+)
pipeline {
agent none
stages {
stage('Test matrix') {
matrix {
axes {
axis {
name 'OS'
values 'linux', 'macos', 'windows'
}
axis {
name 'NODE_VERSION'
values '20', '22'
}
}
stages {
stage('Test') {
agent { label "${OS}" }
steps {
sh 'npm ci && npm test'
}
}
}
}
}
}
}Matrix runs all OS × Node combinations in parallel.
