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

Checkout - Clone repository from SCM
Clean - Remove previous build artifacts
Compile - Compile source code
Run Tests - Execute test suite with parameters
Generate Reports - Create Allure and Extent reports
Post Actions - Publish reports and send notifications

Parameterized Build

Parameter	Type	Options	Description
BROWSER	Choice	chrome, firefox, edge	Browser for execution
TAGS	Choice	@Smoke, @Regression, @E2E	Test tags to execute
HEADLESS	Boolean	true, false	Headless mode toggle

Jenkins Setup

pipeline {
    agent any
    
    parameters {
        choice(name: 'BROWSER', choices: ['chrome', 'firefox', 'edge'])
        choice(name: 'TAGS', choices: ['@Smoke', '@Regression', '@E2E'])
        booleanParam(name: 'HEADLESS', defaultValue: false)
    }
    
    stages {
        stage('Run Tests') {
            steps {
                bat "mvn clean test -Dbrowser=${BROWSER} -Dcucumber.filter.tags=${TAGS}"
            }
        }
    }
}

Report Publishing

Best Practices

Code Quality

Follow SOLID principles
Implement DRY (Don't Repeat Yourself)
Use meaningful variable and method names
Add comments for complex logic
Maintain consistent code formatting

Test Design

Write independent test scenarios
Use appropriate wait strategies
Avoid hard-coded values
Implement proper exception handling
Keep tests atomic and focused

Framework Maintenance

Regular dependency updates
Code review for all changes
Refactor duplicate code
Update documentation
Monitor test flakiness

Naming Conventions

// Page Objects
public class LoginPage extends BasePage {}

// Step Definitions
@Given("user is on the login page")
public void userIsOnTheLoginPage() {}

// Feature Files
Feature: User Login Functionality
  Scenario: Successful login with valid credentials

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>
