CI CD Integration – Setting up Jenkins or Azure DevOps pipelines - Nytrotype/Selenium-with-Java-automation-work GitHub Wiki

Introduction

Continuous Integration (CI) and Continuous Deployment (CD) enable automated testing, faster development cycles, and reliable software releases. Integrating Selenium test automation with Jenkins or Azure DevOps ensures seamless execution and reporting in CI/CD workflows.

1. Why CI/CD for Test Automation?

🔹 Automates test execution after each code commit.
🔹 Improves software reliability by catching defects early.
🔹 Enables parallel execution across multiple environments.
🔹 Supports continuous feedback loops in Agile development.
🔹 Integrates with reporting tools for actionable insights.

2. CI/CD Setup with Jenkins

Prerequisites:

✅ Install Jenkins: [Download Jenkins](https://www.jenkins.io/download/)
✅ Install Git & Maven: Required for dependency management.
✅ Configure Java & Selenium WebDriver in Jenkins nodes.

Step 1: Install Jenkins Plugins

🔹 Navigate to Manage Jenkins > Plugin Manager.
🔹 Install the following essential plugins:

• Maven Integration Plugin
• TestNG Results Plugin
• GitHub Plugin
• Allure Reports Plugin

Step 2: Create a Jenkins Job for Selenium

🔹 Go to Jenkins Dashboard → New Item → Freestyle Project
🔹 Configure GitHub Repository (Under Source Code Management)
🔹 Add Maven Commands in Build Section:

mvn clean test

Step 3: Trigger Build Automatically

🔹 Configure Webhooks in GitHub for automatic builds.
🔹 Set up "Build Triggers" to run tests on every Git push.

Step 4: Generate Test Reports

🔹 Use Extent Reports or Allure Reports to display test results.
🔹 Enable TestNG Reports Plugin for structured execution summaries.

3. CI/CD Setup with Azure DevOps Pipelines

Prerequisites:

✅ Set up Azure DevOps Organization & Repository.
✅ Install Azure DevOps CLI (for pipeline management).
✅ Ensure Test Runner Agents support Java & Selenium WebDriver.

Step 1: Create an Azure DevOps Pipeline

🔹 Go to Azure DevOps → Pipelines → Create Pipeline
🔹 Select GitHub Repository as the source.
🔹 Choose "Starter Pipeline" for a new YAML-based pipeline.

Step 2: Define the YAML Pipeline Configuration

Create .azure-pipelines.yml in your repo:

trigger:
  - main

pool:
  vmImage: 'ubuntu-latest'

steps:
  - script: mvn clean install
    displayName: 'Build and Test Selenium Automation'
  - task: PublishTestResults@2
    inputs:
      testResultsFiles: '**/test-output/*.xml'

Step 3: Enable Test Report Generation

🔹 Add Allure Reports plugin to pipeline steps.
🔹 Use "PublishTestResults@2" to send reports to Azure DevOps dashboard.

Step 4: Automate CI/CD Deployments

🔹 Set up Release Pipelines to deploy validated test results to staging environments.
🔹 Configure notifications & alerts for failed test cases.

4. Best Practices for CI/CD in Selenium Automation

✅ Use Parallel Execution for faster test cycles.
✅ Optimize Test Data Management for dynamic environments.
✅ Maintain Clean Branching Strategy to avoid conflicts.
✅ Implement Retry Mechanisms for flaky tests.
✅ Integrate Logging & Reports for easy debugging.
