Key Features

• Page Object Model (POM) — All UI interactions encapsulated in page classes
• Parallel Execution — ThreadLocal DriverManager enables safe parallel test runs
• Data Driven Testing — TestNG DataProvider + Apache POI for Excel-based test data
• Cucumber BDD — Gherkin feature files for business-readable test scenarios
• Cross-browser Testing — Chrome, Firefox, Edge support via WebDriverManager
• CI/CD Integration — Jenkins pipeline + GitHub Actions for continuous execution
• Auto Screenshot — Captures screenshots automatically on test failure
• Extent Reports — Detailed HTML reports with pass/fail/skip statistics
• Configurable — All settings managed via config.properties

---

Design Patterns Used

Pattern	Implementation
Page Object Model	BasePage, LoginPage, ProductsPage
Singleton	DriverManager (ThreadLocal)
Factory Method	DriverManager.initDriver() browser selection
Data Provider	TestNG @DataProvider for data driven tests

---

Test Cases Covered

Test ID	Description	Type
TC001	Valid login with correct credentials	Smoke + Regression
TC002	Invalid login shows error message	Regression
TC003	Empty credentials shows validation	Regression
TC004	Data driven login (multiple users)	Regression
TC005	Logout returns to login page	Regression
TC006	Products page title verification	Regression
TC007	Products are displayed on page	Regression
TC008	Add product to cart increments count	Regression
TC009	Product has valid name and price	Regression

How to Run

Prerequisites

• Java 11+
• Maven 3.6+
• Chrome browser installed

Run All Tests

mvn clean test

Run Smoke Tests Only

mvn clean test -Dgroups=smoke

Run on Specific Browser

mvn clean test -Dbrowser=firefox

Run in Headless Mode

mvn clean test -Dheadless=true

Run with Specific TestNG Suite

mvn clean test -DsuiteXmlFile=testng.xml

---

CI/CD Pipeline

Jenkins:

• Checkout → Build → Smoke Tests → Regression Suite → Publish Report
• Auto-archives screenshots on failure
• Publishes Extent HTML report

GitHub Actions:

• Triggers on push to main / develop
• Runs headless Chrome on Ubuntu
• Uploads test reports and failure screenshots as artifacts

---

Results Achieved (Production Framework)

Metric	Result
Regression time reduction	40% (3 days to 6 hours)
Test coverage	95%+
Production defect escapes	Zero
Test cases automated	300+
Parallel thread execution	3 threads
