+## Implemented Tests
+
+All four required tasks are complete, plus additional bonus coverage. The full suite runs **9 scenarios (38 steps)**, all passing.
+
+### Required tasks
+- **Login page title** ([login.feature](features/login.feature)) — corrected the expected title to "Swag Labs" so the failing scenario passes.
+- **Login error message** ([login.feature](features/login.feature)) — added a step asserting the locked-out user's error banner.
+- **Successful purchase flow** ([purchase.feature](features/purchase.feature)) — implemented the full checkout (cart → checkout → customer info → continue → finish → order confirmation) via a new [purchase.steps.ts](steps/purchase.steps.ts) and [purchase.page.ts](pages/purchase.page.ts).
+- **Product price sort** ([product.feature](features/product.feature)) — parameterized the price (low→high / high→low) sort using a Scenario Outline and Examples table.
+
+### Bonus coverage
+Added to cover important paths the original suite missed:
+
+- **Parameterized login errors** ([login.feature](features/login.feature)) — a Scenario Outline validating the "Username is required" and "Password is required" errors for empty credentials. Reuses the existing error-message validation to demonstrate data-driven testing.
+- **Successful login happy-path** ([login.feature](features/login.feature)) — confirms a valid login lands on the inventory page and renders all 6 products (the suite previously had no positive login assertion).
+- **Checkout required-field validation** ([purchase.feature](features/purchase.feature)) — confirms the checkout form blocks continuing without customer info, asserting the "First Name is required" error.
