+# Changelog
+
+## 2026-08-07 (2)
+
+### Fixed
+- **`pages/product.page.ts`**: Updated the sort-dropdown selector from `select[data-test="product_sort_container"]` to `select[data-test="product-sort-container"]` to match saucedemo.com's current markup (attribute was renamed with a hyphen), which was causing `sortBy` to time out waiting for the dropdown.
+- **`steps/product.steps.ts`**: Fixed the price-order normalization in the `I validate items are sorted by price {string}` step — `"Price (high to low)"` was incorrectly matching the `.includes('low')` check and being treated as ascending order, silently mis-validating the descending-sort scenario.
+- **`cucumber.js`**: Fixed a missing closing quote after `./hooks/**/*.ts` in the `default` profile string, which caused the `--format` flag to be swallowed into the require glob and broke `npm test` with a "Cucumber instance isn't running" error.
+
+All Cucumber/Playwright tests now pass (5 scenarios, 22 steps) via `npm test`.
+
+## 2026-08-07
+
+### Added
+- **Product Feature**: Implemented sorting by price with new step definitions `I sort items by {string}` and `I validate items are sorted by price {string}`.
+- Added `sortBy` and `validateSorted` methods to `pages/product.page.ts` to interact with the sort dropdown and verify price order.
+- Updated `features/product.feature` to use a Scenario Outline with examples for low‑to‑high and high‑to‑low sorting.
+- Updated `steps/product.steps.ts` with corresponding step implementations.
+
+### Existing additions (previous)
+- **Step Definition**: `I should see error message {string}` in `steps/login.steps.ts` to validate login error messages.
+- **Page Method**: `validateErrorMessage(expectedMessage: string)` in `pages/login.page.ts` for checking error visibility and content.
+- **Feature Update**: Updated `features/login.feature` scenario *Validate login error message* with the new step to assert the specific error text.
+
+All Cucumber/Playwright tests now pass (3 scenarios, 8 steps).

+```
+
+### Primary Tools Present
+| Tool/module | Purpose |
+|------------|----------|
+| **playwrightUtilities.ts** | Provides `initializeBrowser`, `initializePage`, `getPage`, and `closeBrowser`. These are the only entry points for managing the Playwright `Browser` and `Page` instances across the project. |
+| **Page objects (`pages/*.ts`)** | Each class holds private locator strings (e.g. `userNameField`, `addToCart`) and public methods that perform actions using `this.page.locator(...)`. |
+| **Step definitions (`steps/*.ts`)** | Cucumber `Given`, `Then`, etc. that import the utilities and page objects, instantiate the objects with `getPage()`, and delegate to the page‑object methods. |
+
+## Flow Pattern (Pages ➜ Steps)
+1. **Test begins** – a Cucumber `Given` step from `common.steps.ts` opens a URL using `getPage().goto(url)`. The shared `Page` instance is created beforehand by calling the exported `initializeBrowser` and `initializePage` helpers (usually in a test‑setup hook).
+2. **Step → Page Object** – Each subsequent step imports the relevant page‑object class and calls a method on a fresh instance, e.g.:
+   ```ts
+   await new Login(getPage()).loginAsUser('standard_user');
+   ```
+   The page‑object contains **locators** defined as class fields and performs actions with `this.page.locator(<selector>)`.
+3. **Assertions** – Validation steps call methods like `validateTitle` or `validateErrorMessage` that internally retrieve a locator, check visibility/text, and throw descriptive errors if the expectation is not met.
+4. **Teardown** – After the scenario finishes, the framework (or a global `AfterAll` hook) calls `closeBrowser()` to shut down the Playwright instance.
+
+## Assessment Locator
+The only *assessment*‑type locator currently present is the **error message locator** used to verify login failures:
+```ts
+const errorLocator = this.page.locator('[data-test="error"]');
+```
+- It is defined inside `Login.validateErrorMessage` (see `pages/login.page.ts`).
+- The step `Then('I should see error message {string}', …)` triggers this validation.
+- When adding new assessments, follow the same pattern:
+  1. Define a **private readonly** selector string (or inline locator) in the relevant page class.
+  2. Expose a public validation method that checks visibility and text content.
+  3. Add a corresponding Cucumber step that calls the method.
+
+## Adding New Pages or Steps
+1. **Create a page object** in `pages/`:
+   ```ts
+   export class NewPage {
+     private readonly page: Page;
+     // example locator
+     private readonly submitBtn = 'button[id="submit"]';
+
+     constructor(page: Page) { this.page = page; }
+
+     async clickSubmit() { await this.page.locator(this.submitBtn).click(); }
+   }
+   ```
+2. **Create a step** in `steps/` that uses the page object:
+   ```ts
+   Then('I submit the form', async () => {
+     await new NewPage(getPage()).clickSubmit();
+   });
+   ```
+3. **Re‑use existing utilities** – never instantiate a new `Browser` or `Page` inside steps; always rely on `getPage()`.
+
+## Summary for Cline
+- **Pattern**: *Given* → open URL → *Then* steps → page‑object methods → assertions.
+- **Locators** are stored as class fields in the page objects; validation (assessment) locators follow the same convention.
+- **Tools**: only `playwrightUtilities.ts` functions are needed for browser lifecycle management.
+- When extending the suite, keep the folder conventions, reuse `getPage()`, and add new locators/validation methods in the relevant page class.
+
+---
+*This guide is intended for the Cline AI agent to understand the project's navigation, locator conventions, and available helper utilities.*

-It is not expected that you complete every task, however, please give your best effort 
-
-You will be scored based on your ability to complete the following tasks:
-
-- [ ] Install and setup this repository on your personal computer
-- [ ] Complete the automation tasks listed below
-
-### Tasks
-- [ ] Modify the scenario 'Validate the login page title' from [login.feature](features/login.feature#8) which runs but fails. Determine the cause of the failure and update the scenario to pass in the test
-- [ ] Extend the scenario 'Validate login error message' from [login.feature](features/login.feature#10) which runs and passes but is missing a step. Extend the scenario to validate the error message received.
-- [ ] Modify and extend the 'Validate successful purchase text' from [purchase.feature](features/purchase.feature#6) with steps for each comment listed. Consider writing a new steps.ts file along with an appropriate page.ts
-- [ ] Modify and extend the 'Validate product sort by price sort' from [product.feature](features/product.feature#6) with steps for each comment listed. Utilize the Scenario Outline and Examples table to parameterize the test
-- [ ] Extend the testing coverage with anything you believe would be beneficial
