1. Write the scenario matrix for the five steps.
2. Register and log in; extract the token.
3. Add a product to the cart, checkout, and assert the order body and Location header.
4. Add failure rows: empty cart, no token, unknown product.
5. Planned mistake: assert the whole JSON as a string; add a field and watch the test break; fix with field-level assertions.
6. Run the test against the Testcontainers-backed app.
