How to test pricing?

Pricing testing (cost formation) includes several key stages:

1. Verification of calculations — ensure that prices are calculated according to specified rules, discounts, taxes, and other parameters.

2. Testing usage scenarios — check how pricing behaves under various conditions: promotions, seasonal discounts, different user categories.

3. Competitiveness analysis — compare prices with competitors to understand how adequate the pricing is in the market.

4. Monitoring impact on sales and revenue — after implementing changes, analyze how they affect user behavior and financial indicators.

5. Automation of tests — create automated tests to verify the business logic of pricing.

Example: if you have a rule "10% discount for regular customers," you need to verify that the price indeed decreases by 10% for such customers, and not for others.
