🚀 E2E Test Automation Framework

Build Status Coverage License Java Selenium Cucumber

Enterprise-grade test automation framework implementing Page Object Model (POM) design pattern with Behavior-Driven Development (BDD) using Cucumber, Selenium WebDriver, and TestNG. Features dual reporting mechanisms (Allure & Extent), Jenkins CI/CD integration, and cross-browser testing capabilities.

🏗 Project Architecture

Design Patterns Implemented

1. Page Object Model (POM)

pages/
├── BasePage.java           → Common methods for all pages
├── LoginPage.java          → Login page elements & actions
├── ProductsPage.java       → Products page elements & actions
└── CheckoutPage.java       → Checkout page elements & actions

Benefits:

  • Centralized element locators
  • Reduced code duplication
  • Easy maintenance
  • Improved readability

2. Singleton Pattern

  • DriverManager implements singleton for WebDriver instance management
  • Ensures single driver instance per thread

3. ThreadLocal Pattern

  • Thread-safe WebDriver for parallel execution
  • Isolated driver instances per test thread

🐛 Troubleshooting

Common Issues & Solutions

Issue 1: Maven Dependencies Not Downloading

# Solution
mvn dependency:purge-local-repository
mvn clean install -U

Issue 2: WebDriver Not Found

# Verify internet connection
# WebDriverManager downloads drivers automatically
# Check Maven logs for download issues

Issue 3: Tests Failing with ElementNotFoundException

# Increase wait times in config.properties
explicit.wait=30
implicit.wait=15

Issue 4: Feature Files Not Recognized

# Install Cucumber plugin in IDE
# Mark src/test/resources as Test Resources Root
# Rebuild project: Build → Rebuild Project

Issue 5: Allure Report Not Generating

# Clean and regenerate
mvn clean test
mvn allure:report

Issue 6: Port Already in Use (Jenkins)

# Change Jenkins port
java -jar jenkins.war --httpPort=9090

Debug Mode

# Run tests in debug mode with detailed logs
mvn clean test -X -Dcucumber.filter.tags="@Smoke"

Log Levels

<!-- Adjust in log4j2.xml -->
<Root level="debug">  <!-- Change to: info, warn, error -->
    <AppenderRef ref="Console"/>
    <AppenderRef ref="RollingFile"/>
</Root>
