Setup Instructions

1. Start Jenkins

docker compose up -d

2. Access Jenkins

• URL: http://localhost:8080
• Get password:

docker exec -it jenkins cat /var/jenkins_home/secrets/initialAdminPassword

3. Install Python in Jenkins Container

docker exec -it jenkins bash
apt-get update && apt-get install -y python3 python3-venv python3-pip
exit

4. Create Pipeline Job

1. New Item → Pipeline
2. Configure with GitHub repository
3. SCM: Git
4. Repository URL: https://github.com/AkshayKumarTN/jenkins-python-pytest-demo
5. Branch: */master
6. Script Path: Jenkinsfile

5. Build Pipeline

Click "Build Now" and view results

Test Results

• ✅ 2 tests pass:
  • test_addition
  • test_subtraction
• ❌ 1 test fails (intentional):
  • test_failure_example (demonstrates failure reporting)

Pipeline Stages

1. Install dependencies - Creates Python virtual environment
2. Run tests - Executes pytest with JUnit XML reporting
3. Publish Report - Displays test results in Jenkins
