**Key Files & Their Purpose:**
-   `playwright.config.ts`: Defines global settings, projects, reporters (standard HTML reporter is sufficient), and base URLs.
-   `fixture/pom/test-options.ts`: Responsible for merging different sets of fixtures.
-   `fixture/api/schemas.ts`: Contains Zod schemas used for validating API request payloads and response bodies.
-   `pages/**/*.ts`: Contain Page Object classes, structured as per the guidelines below.
-   Any new utility functions or classes should be created in appropriate files within this structure.

## Code Style & Best Practices

**General:**
-   Adhere strictly to the settings defined in `.prettierrc`.
-   All code must be type-safe. Leverage TypeScript`s features to ensure this.
-   Avoid `any` type unless absolutely necessary and provide a justification.
-   Use modern JavaScript features (ESNext) where appropriate (e.g., optional chaining, nullish coalescing).
-   No commented-out code in the final output. Explanatory comments are acceptable if they clarify complex logic.

**Playwright Specific:**
1.  **Page Object Model (POM) (`pages/**/*.ts`):**
    * Page classes should encapsulate locators (as getters) and methods representing user interactions or assertions for that page/component.
    * **Constructor:** Must accept `page: Page` (from Playwright) as its first argument, using the `private` shorthand.
        ```

typescript
        constructor(private page: Page) {}


        ```
    * **Locators:**
        * Define all locators as public `get` accessors.
        * **Prioritize user-facing locators (Playwright`s recommendations):**
            1.  `this.page.getByRole()`
            2.  `this.page.getByText()`
            3.  `this.page.getByLabel()`
            4.  `this.page.getByPlaceholder()`
            5.  `this.page.getByAltText()`
            6.  `this.page.getByTitle()`
        * Use `this.page.frameLocator()` for elements within iframes.
        * Only use `this.page.locator()` (CSS or XPath) as a last resort when semantic locators are not feasible or stable. If using `this.page.locator()`, prefer `data-testid` attributes for robustness (e.g., `this.page.locator('[data-testid="error-message"]')`).
        * Ensure locators are specific enough to avoid ambiguity (e.g., using `.first()` if multiple elements match and it`s intended).
    * **Methods:**
        * Methods should represent complete user actions or flows (e.g., `publishArticle(...)`, `navigateToEditArticlePage()`) or retrieve page state (e.g., `getPublishErrorMessageText()`).
        * Methods performing actions **must include validation** to confirm the action`s success. This can involve:
            * Waiting for network responses: `await this.page.waitForResponse(response => ...)`
            * Asserting element visibility/state: `await expect(this.page.getByRole('heading', { name: title })).toBeVisible();`
            * Checking URL changes or other relevant side effects.
        * Provide comprehensive JSDoc comments for all public methods, including:
            * A clear description of what the method does.
            * `@param` for each parameter with its type and description.
            * `@returns {Promise<void>}` for action methods or `Promise<Type>` for methods returning data.
            * Mention any important pre/post-conditions or potential errors if applicable.
        * Avoid methods that perform only a single Playwright action (e.g., a method solely for `await someButton.click()`). Incorporate such actions into larger, more meaningful user flow methods.

    * **Example Page Object (`ArticlePage`):**
        ```

typescript
        import { Page, Locator, expect } from '@playwright/test';

        export class ArticlePage {
            constructor(private page: Page) {}

            }
        }


        ```

2.  **Tests (`tests/**/*.spec.ts`):**
    * Use the merged fixtures from `fixture/pom/test-options.ts` (e.g., `test('should display user dashboard', async ({ articlePage, otherPage }) => { ... })`).
    * Tests should be independent and focused on a single piece of functionality or user story.
    * Employ web-first assertions (`expect(locator).toBeVisible()`, `expect(page).toHaveURL()`).
    * Use built-in configuration objects like `devices` from `playwright.config.ts` when appropriate (e.g., for responsive testing).
    * Avoid hardcoded timeouts. Rely on Playwright`s auto-waiting mechanisms and web-first assertions. If a specific timeout is needed for an assertion, pass it as an option: `expect(locator).toBeVisible({ timeout: 5000 });`.
    * Group related tests using `test.describe()`.
    * Use `test.beforeEach` and `test.afterEach` for setup and teardown logic specific to a group of tests.
    * For global setup (like authentication), use the `auth.setup.ts` pattern.

3.  **API Tests (`tests/API/**/*.spec.ts`):**
    * Utilize `apiRequest` context (from fixtures) for making API calls.
    * Use Zod schemas from `fixture/api/schemas.ts` to validate request payloads and response structures.
    * Verify status codes, headers, and response bodies thoroughly.

4.  **Fixtures (`fixture/**/*.ts`):**
    * Clearly define the purpose and usage of each fixture with JSDoc.
    * Ensure fixtures are scoped correctly (worker vs. test) based on their purpose.
    * `fixture/pom/page-object-fixture.ts` should define how page objects are instantiated and provided to tests.
    * `fixture/api/api-request-fixture.ts` should configure the `APIRequestContext` (e.g., base URL from environment variables).

## Output Format & Expectations

-   **Code Generation:** Provide complete, runnable TypeScript code blocks that strictly follow these rules.
-   **Explanations:** When asked for explanations or advice, be clear, concise, and provide actionable recommendations aligned with these guidelines.
-   **Error Handling in Generated Code:** Generated code should include robust error handling where appropriate (e.g., try-catch for API calls if not handled by Playwright`s `toPass` or similar, checks for element states if complex interactions are involved). Standard Playwright assertions usually handle waits and implicit erroring.
-   **Clarity on Ambiguity:** If a user`s prompt is ambiguous or lacks necessary detail to follow these rules, ask clarifying questions before generating code.

## Things to Avoid

-   Generating overly complex or monolithic functions/classes. Prefer smaller, focused units that adhere to Single Responsibility Principle.
-   Using `page.waitForTimeout()` for arbitrary waits. Rely on web-first assertions and Playwright`s actionability checks.
-   Directly manipulating the DOM (e.g., `page.evaluate()` to change styles or content) unless it`s for a specific, justified testing scenario (like mocking complex browser APIs not supported by Playwright).
-   Hardcoding sensitive data (credentials, API keys) or environment-specific URLs directly in tests or page objects. Use environment variables (`process.env`) accessed via `playwright.config.ts` or fixtures.
-   Suggesting outdated practices or libraries not listed in the Tech Stack.
-   Including commented-out code in the final output, unless it`s a JSDoc or a brief, necessary clarification for exceptionally complex logic that cannot be made self-evident through code structure.
-   Deviating from the specified POM structure and locator strategies.
