Playwright test generation instructions

## Test Writing Guidelines

### Code Quality Standards
- **Locators**: Prioritize user-facing, role-based locators (`getByRole`, `getByLabel`, `getByText`, etc.) for resilience and accessibility. Use `test.step()` to group interactions and improve test readability and reporting.
- **Assertions**: Use auto-retrying web-first assertions. These assertions start with the `await` keyword (e.g., `await expect(locator).toHaveText()`). Avoid `expect(locator).toBeVisible()` unless specifically testing for visibility changes.
- **Timeouts**: Rely on Playwright's built-in auto-waiting mechanisms. Avoid hard-coded waits or increased default timeouts.
- **Clarity**: Use descriptive test and step titles that clearly state the intent. Add comments only to explain complex logic or non-obvious interactions.


### Test Structure
- **Imports**: Start with `import { test, expect } from '@playwright/test';`.
- **Organization**: Group related tests for a feature under a `test.describe()` block.
- **Hooks**: Use `beforeEach` for setup actions common to all tests in a `describe` block (e.g., navigating to a page).
- **Titles**: Follow a clear naming convention, such as `Feature - Specific action or scenario`.


### File Organization
- **Location**: Store all test files in the `tests/` directory.
- **Naming**: Use the convention `<feature-or-page>.spec.ts` (e.g., `login.spec.ts`, `search.spec.ts`).
- **Scope**: Aim for one test file per major application feature or page.

### Assertion Best Practices
- **UI Structure**: Use `toMatchAriaSnapshot` to verify the accessibility tree structure of a component. This provides a comprehensive and accessible snapshot.
- **Element Counts**: Use `toHaveCount` to assert the number of elements found by a locator.
- **Text Content**: Use `toHaveText` for exact text matches and `toContainText` for partial matches.
