Steps to Test Ordering on Nxtbn

1. Create Test Products

• Create multiple products with varying configurations:
  • Product 1: Tracks inventory only.
  • Product 2: Taxable only.
  • Product 3: Both taxable and tracks inventory.
  • Product 4: Non-tracking and non-taxable.

---

2. Set Up Tax Classes

• Define tax classes based on location:
  • Example: Create a tax class "VAT 15%", specifying applicable states, cities, or countries.
  • Rules:
    • If a state and city are specified, the tax applies only to that city.
    • If only a country is specified, the tax applies to the entire country.
    • If multiple tax classes match, the most specific one (e.g., state-level) takes precedence.
• Ensure taxes and delivery rates depend on the shipping address provided during checkout.

Testing Steps

Step 1: Test Orders with Non-Tracking Products

• Place an order with a non-tracking product that is taxable.
• Test with multiple orders across different locations.
• Verify:
  • Tax rates are applied as per the shipping address.
  • Total calculations (subtotal, tax, and shipping) are accurate.

---

Step 2: Test Orders with Tracking Products

• Create an order using a tracking and taxable product.
• Apply a discount code during checkout.
• Verify:
  • Discount is applied correctly.
  • Tax and total calculations are accurate.
  • Inventory is updated properly.

---

Step 3: Test Flat Discount Application

• Place an order and apply a flat discount (e.g., $200 or 10%).
• Do not use a discount code for this test.
• Verify:
  • Discount amount is subtracted correctly.
  • Tax and shipping calculations remain accurate.
  • The final total reflects the discount properly.

---

Step 4: Test Discount Code Scenarios

• Test different discount code configurations:
  • Customer-specific: Restricted to specific customers.
  • Product-specific: Applies only to specific products.
  • Time-limited: Valid for specific periods.
  • New Customers: Applicable only to first-time buyers.
  • Redemption Limits: Limited number of uses.
  • Inactive Codes: Ensure inactive codes cannot be applied.
• Test both flat-rate and percentage-based discounts.
• Place at least 6 orders with varied scenarios:
  • Verify all validations and calculations (excluding tax and shipping) work as expected.
  • Confirm the discount logic aligns with your configurations.

---

Step 5: Test Shipping Rate Calculations

• Set up various shipping rates:
  • Flat rates (e.g., $10 per order).
  • Percentage-based rates (e.g., 5% of the order total).
  • Location-specific rates (e.g., different rates for Dhaka vs. Chattogram).
• Test by placing at least 6 orders with different scenarios:
  • Example 1: Location Dhaka, taxable product, no discount.
  • Example 2: Location Chattogram, non-taxable product.
  • Example 3: Location X with a discount and a taxable product.
• Verify:
  • Shipping rates are calculated as per location.
  • Combined tax, discount, and shipping calculations are accurate.

---

Step 6: Test Stock Updates After Delivery

• Place an order with a stock-tracking product.
• Simulate delivering a part of the order (e.g., deliver 3 items out of 6 in stock).
• Verify:
  • The current stock quantity is reduced only after the product status is marked as delivered.
  • Example:
    • Initial stock: 6.
    • Delivered: 3.
    • Remaining stock: 3.
• Test with multiple products and ensure:
  • Products that do not track inventory remain unaffected.
  • All stock changes are reflected accurately.

---

Step 7: Test Shipping and Billing Address Population

• Place orders and verify that both shipping address and billing address are populated correctly in the database.
• Ensure:
  • The addresses match what was entered during checkout.
  • Address fields such as state, city, and postal code are stored properly.

---

Step 8: Test Customer and Base Currency Storage

• Use a customer currency different from the base currency:
  • Send the currency via the header named Accept-Currency.
  • Ensure:
    • Customer currency is stored in the order table under the correct field.
    • Base currency remains the default for the platform.
    • Currency conversion works accurately.
    • Amounts in customer currency are stored correctly and validated.

---

Step 9: Validate Cost Storage

• Verify all costs are stored with accurate amounts and currencies:
  • Shipping cost.
  • Discount.
  • Total tax.
  • Total price.
• Ensure:
  • Data integrity is maintained.
  • Proper currency fields are used for validation and storage.

Additional Notes

• Refer to the Nxtbn discount and tax models for detailed logic behind calculations.
• Cover edge cases and unexpected inputs to ensure robust testing.
• Ensure validation logic for tax, discount, shipping, and inventory updates is working seamlessly across all scenarios.
