Jenkins

Jenkins is a widely-used open-source automation server. With Gaffer, you can automatically upload and share test reports from your Jenkins pipelines.

Prerequisites

• A Gaffer account with a project
• Your project’s upload token
• A Jenkins instance with a pipeline configured

Setup

1. Add your upload token as a credential

1. Go to Manage Jenkins → Credentials
2. Select the appropriate domain (or global)
3. Click Add Credentials
4. Kind: Secret text
5. Secret: Your Gaffer project upload token
6. ID: gaffer-upload-token
7. Description: Gaffer Upload Token

2. Add the upload step to your Jenkinsfile

pipeline {
    agent any

    environment {
        GAFFER_UPLOAD_TOKEN = credentials('gaffer-upload-token')
    }

    stages {
        stage('Test') {
            steps {
                sh 'npm ci'
                sh 'npm test'
            }
            post {
                always {
                    sh '''
                        curl -X POST https://app.gaffer.sh/api/upload \
                            -H "X-API-Key: $GAFFER_UPLOAD_TOKEN" \
                            -F "files=@test-results/junit.xml" \
                            -F 'tags={"commitSha":"'"$GIT_COMMIT"'","branch":"'"$GIT_BRANCH"'"}'
                    '''
                    junit 'test-results/junit.xml'
                }
            }
        }
    }
}

Environment Variables

Jenkins provides these variables for your pipeline:

Variable	Description	Example
$GIT_COMMIT	Full commit SHA	abc123def456...
$GIT_BRANCH	Branch name (may include origin/)	origin/main, origin/feature/login
$BRANCH_NAME	Branch name (multibranch pipelines)	main, feature/login
$BUILD_NUMBER	Build number	123
$JOB_NAME	Job name	my-app/main

Tip

In multibranch pipelines, use $BRANCH_NAME instead of $GIT_BRANCH for cleaner branch names without the origin/ prefix.

Examples

Playwright

pipeline {
    agent {
        docker {
            image 'mcr.microsoft.com/playwright:v1.40.0-jammy'
        }
    }

    environment {
        GAFFER_UPLOAD_TOKEN = credentials('gaffer-upload-token')
    }

    stages {
        stage('Install') {
            steps {
                sh 'npm ci'
            }
        }
        stage('Test') {
            steps {
                sh 'npx playwright test'
            }
            post {
                always {
                    sh '''
                        curl -X POST https://app.gaffer.sh/api/upload \
                            -H "X-API-Key: $GAFFER_UPLOAD_TOKEN" \
                            -F "files=@playwright-report/index.html" \
                            -F 'tags={"commitSha":"'"$GIT_COMMIT"'","branch":"'"$BRANCH_NAME"'","test_framework":"playwright","test_suite":"e2e"}'
                    '''
                    archiveArtifacts artifacts: 'playwright-report/**'
                }
            }
        }
    }
}

Jest with JUnit Reporter

pipeline {
    agent any

    environment {
        GAFFER_UPLOAD_TOKEN = credentials('gaffer-upload-token')
    }

    stages {
        stage('Test') {
            steps {
                sh 'npm ci'
                sh 'npm test -- --reporters=default --reporters=jest-junit'
            }
            post {
                always {
                    sh '''
                        curl -X POST https://app.gaffer.sh/api/upload \
                            -H "X-API-Key: $GAFFER_UPLOAD_TOKEN" \
                            -F "files=@junit.xml" \
                            -F 'tags={"commitSha":"'"$GIT_COMMIT"'","branch":"'"$BRANCH_NAME"'","test_framework":"jest"}'
                    '''
                    junit 'junit.xml'
                }
            }
        }
    }
}

Declarative with Scripted Post

pipeline {
    agent any

    stages {
        stage('Test') {
            steps {
                sh 'npm ci && npm test'
            }
        }
    }

    post {
        always {
            withCredentials([string(credentialsId: 'gaffer-upload-token', variable: 'GAFFER_UPLOAD_TOKEN')]) {
                sh '''
                    # Clean branch name (remove origin/ prefix)
                    CLEAN_BRANCH="${GIT_BRANCH#origin/}"

                    curl -X POST https://app.gaffer.sh/api/upload \
                        -H "X-API-Key: $GAFFER_UPLOAD_TOKEN" \
                        -F "files=@test-results/junit.xml" \
                        -F 'tags={"commitSha":"'"$GIT_COMMIT"'","branch":"'"$CLEAN_BRANCH"'"}'
                '''
            }
        }
    }
}

Using CTRF Format

For a standardized format across all your test frameworks, consider using CTRF:

stage('Test') {
    steps {
        // Install the CTRF reporter for your framework:
        // npm install --save-dev jest-ctrf-json-reporter
        // npm install --save-dev playwright-ctrf-json-reporter
        // npm install --save-dev vitest-ctrf-json-reporter
        sh 'npm install --save-dev jest-ctrf-json-reporter'
        sh 'npm test -- --reporter=jest-ctrf-json-reporter'
    }
    post {
        always {
            sh '''
                curl -X POST https://app.gaffer.sh/api/upload \
                    -H "X-API-Key: $GAFFER_UPLOAD_TOKEN" \
                    -F "files=@ctrf-report.json" \
                    -F 'tags={"commitSha":"'"$GIT_COMMIT"'","branch":"'"$BRANCH_NAME"'"}'
            '''
        }
    }
}

Troubleshooting

Report not uploading

• Verify the credential ID matches (gaffer-upload-token)
• Ensure the upload is in a post { always { } } block
• Check the file path is correct relative to the workspace

401 Unauthorized

• Check your upload token starts with gfr_
• Verify the credential is accessible to the pipeline

Branch name includes “origin/”

Use ${GIT_BRANCH#origin/} to strip the prefix:

sh '''
    CLEAN_BRANCH="${GIT_BRANCH#origin/}"
    curl ... -F 'tags={"branch":"'"$CLEAN_BRANCH"'"}'
'''

curl not found

Ensure curl is installed on your Jenkins agent or use a Docker image that includes it.
