The project aims to validate the functionality and reliability of a payment gateway system through automated testing. By using TestNG as the core framework, various design patterns, state management techniques, and reporting tools are integrated to ensure comprehensive test coverage and insightful reporting.

TestNG is utilized for its flexibility in organizing and executing test cases, providing parallel execution capabilities and detailed test configurations.

Implemented to facilitate testing of the payment gateway with different credit card scenarios. This pattern allows for reusable test logic and efficient handling of varied inputs.

Singleton pattern is leveraged to manage state and ensure consistency across different test scenarios. State management tools are employed to simulate and control various transaction flows, validating different payment processing scenarios effectively.

Extent Reports are integrated for comprehensive test reporting. These reports offer detailed insights into test execution results, facilitating easy identification of test outcomes, failures, and trends.

Modular and Reusable Tests: The use of design patterns like Factory ensures modular test cases that can be easily extended or modified for different card types and scenarios.

State Management for Realistic Testing: Effective simulation of transaction flows through state management ensures tests accurately reflect real-world payment processing conditions.

Insightful Reporting: Extent Reports provide clear, visually appealing reports that aid in understanding test results, facilitating informed decision-making and communication with stakeholders.

Continuous Integration: Integration with CI/CD pipelines to automate test execution and integration testing, ensuring ongoing validation of payment gateway functionality with each code change.

Enhanced Error Handling: Strengthening error handling mechanisms to gracefully manage unexpected scenarios during testing, enhancing test robustness and reliability.

Test Data Management: Streamlining management of test data, including credit card details and expected outcomes, to maintain test efficiency and accuracy.
