Create Page Object Model

Generate a POM class for the specified page following all E2E test conventions.

Workflow

1. Determine the page name from the user's request (e.g., "Settings" → settings.page.ts)
2. Check if a POM already exists for this page in e2e/poms/. If so, add methods to the existing POM — do NOT create a second POM for the same page
3. Identify the base page class in e2e/poms/base.page.ts and extend it
4. Read the target page in the application to understand its elements and interactions
5. Generate the POM file following the template below
6. Verify the file compiles with no TypeScript errors

Rules

• One page = one POM — every distinct page/view gets exactly one POM file
• All POMs extend the base page class — check e2e/poms/base.page.ts for the abstract class
• Implement setUp() and tearDown() — inherited from the base class
• Reusable helpers belong in BasePage — if a helper method is useful across multiple POMs (e.g., waitForToast, dismissModal), it must live in BasePage, not in a derived POM. Derived POMs should contain only page-specific behavior. If you find yourself writing the same helper in a second POM, promote it to BasePage immediately
• NEVER reference another POM from within a POM — if a test needs multiple pages, the spec file orchestrates between POMs
• Detailed JSDoc on every public method — describe what it does step by step, with @param tags
• Use the selector priority order: getByRole() > getByLabel() > getByText() > getByPlaceholder() > locator()

POM Structure

Organise every POM with these clearly separated sections using comment banners:

import { Page, Locator, expect } from '@playwright/test';
// TODO: Import your project's base page class
import { BasePage } from './base.page';

export class FeaturePage extends BasePage {
    constructor(page: Page) {
        super(page);
    }

    // ==========================================
    // LIFECYCLE (from BasePage)
    // ==========================================

    /**
     * Navigates to the feature page and cleans up any stale data
     * left by previous failed test runs.
     *
     * Steps:
     * 1. Navigates to /feature via direct URL.
     * 2. Waits for the page heading to be visible.
     * 3. Deletes any items matching the test data pattern.
     */
    async setUp(): Promise<void> {
        // TODO: Implement navigation and cleanup

    get heading(): Locator {
        return this.page.getByRole('heading', { name: 'Feature Name' });
    }

    /** The "Create" button that opens the creation modal. */
    get createButton(): Locator {

JSDoc Requirements

Every public method MUST have a JSDoc comment with:

1. Summary line — what the method does
2. Steps block — numbered list of what happens when called
3. @param tags — for every parameter
4. @returns tag — if the method returns a value

This is critical because LLMs read these comments to understand what actions are available and generate test specs from them.

/**
 * Updates an existing item's name and value.
 *
 * Steps:
 * 1. Locates the item row by its current name.
 * 2. Clicks the "Edit" button within that row.
 * 3. Clears and fills the name field with the new name.
 * 4. Clears and fills the value field with the new value.
 * 5. Clicks "Save" and waits for the edit modal to close.
 * 6. Waits for the success toast notification to appear.
 *
 * @param currentName - The item's current display name (used to locate the row)
 * @param newName     - The new display name
 * @param newValue    - The new value
 */
async editItem(currentName: string, newName: string, newValue: string): Promise<void> {

Naming

• File: e2e/poms/{feature}.page.ts (lowercase, kebab-case feature name)
• Class: {Feature}Page (PascalCase)
• The feature name must match the corresponding spec and test-data files

See references/pom-template.md for the full boilerplate.
