• Set up multiple payment methods, including valid and invalid options (e.g., credit cards, PayPal, gift cards).
• Ensure that each payment method has different states (e.g., active, expired, insufficient funds).

Order History

• Create a history of orders with different statuses (e.g., placed, processing, shipped, delivered).
• Include orders with various issues (e.g., cancellations, returns, disputes).

Example Data Setup Script

-- Create user accounts
INSERT INTO users (username, password, role) VALUES
('customer1', 'password123', 'customer'),
('admin1', 'admin123', 'admin'),
('guest1', 'guest123', 'guest');

-- Create product catalog
INSERT INTO products (id, name, price, stock) VALUES
(1, 'Product A', 19.99, 100),
(2, 'Product B', 99.99, 50),
(3, 'Product C', 49.99, 0);

-- Create delivery addresses
INSERT INTO addresses (user_id, street, city, state, zip, additional_details) VALUES
(1, '123 Main St', 'Anytown', 'CA', '12345', 'Apt 2'),
(1, '456 Elm St', 'Othertown', 'NY', '67890', NULL);

-- Create payment methods
INSERT INTO payment_methods (user_id, method, status) VALUES
(1, 'Credit Card 1234', 'active'),
(1, 'PayPal', 'inactive');

-- Create order history
INSERT INTO orders (user_id, product_id, quantity, status) VALUES
(1, 1, 2, 'placed'),
(1, 2, 1, 'processing'),
(1, 1, 1, 'shipped');

Prioritization and Traceability of Test Cases

Prioritizing test cases is essential for efficient testing, especially when resources are limited. Test cases should be ranked based on their importance and the potential impact of failures. Here are some guidelines for prioritizing test cases:

High Priority

• Critical Functionality: Test cases that verify essential features, such as order placement and delivery confirmation.
• High-Risk Scenarios: Test cases that address common failure points or security vulnerabilities.
• High-Volume Workflows: Test cases that cover workflows with a large number of users or transactions.

Medium Priority

• Secondary Functionality: Test cases that verify important but not critical features, such as order history and status updates.
• Edge Cases: Test cases that explore the limits of the system's input ranges.
• User Experience: Test cases that ensure a smooth and intuitive user experience.

Low Priority

• Nice-to-Have Features: Test cases that verify non-essential features or minor enhancements.
• Edge Cases with Low Impact: Test cases that cover rare or unlikely scenarios.

Traceability

Traceability ensures that each test case is linked to specific requirements, which helps in verifying that all requirements are tested. Here are some best practices for maintaining traceability:

• Requirement Traceability Matrix (RTM): Create a matrix that maps each test case to the corresponding requirement.
• Documentation: Document the rationale for each test case, including the requirements it covers and the expected behavior.
• Version Control: Use version control systems to track changes to test cases and requirements over time.

Example Requirement Traceability Matrix

Test Matrix for Delivery Tracking

A test matrix is a structured way to organize and manage test cases. It helps in ensuring that all aspects of the system are tested and provides a clear overview of the testing effort. Here is a test matrix for delivery tracking:
