How do I set up environment and install playwright?

# Step 1: Environment Setup 1. **Install Node.js**: Download and install Node.js version 20.x, 22.x, or 24.x from [nodejs.org](https://nodejs.org/). Verify with `node --version` and `npm --version` in your terminal. 2. **Install VS Code**: Download [Visual Studio Code](https://code.visualstudio.com/) (recommended IDE). 3. **Create Playwright Project**: ```bash mkdir playwright-demo cd playwright-demo npm init playwright@latest ``` - Choose TypeScript (recommended), add GitHub Actions workflow, install browsers. 4. **Install Browsers**: ```bash npx playwright install ``` This scaffolds a project with config, tests folder, and example test.

How do I write and run your first test?

# Step 2: First Test Open `tests/example.spec.ts` (created by init): ```ts import { test, expect } from '@playwright/test'; test('has title', async ({ page }) => { await page.goto('https://playwright.dev/'); await expect(page).toHaveTitle(/Playwright/); }); ``` **Run Tests**: - All: `npx playwright test` - Headed: `npx playwright test --headed` - UI Mode: `npx playwright test --ui` - Report: `npx playwright show-report` This test navigates to playwright.dev and asserts the title contains 'Playwright'. Tests run in parallel across browsers by default.

How do I master locators and interactions?

# Step 3: Locators & Actions **Key Locators** (resilient to changes): - `page.getByRole('button', { name: 'Submit' }).click()` - `page.getByLabel('Email').fill('user@example.com')` - `page.getByText('Welcome').toBeVisible()` - `page.getByTestId('cart')` **Example Test**: ```ts test('interactions', async ({ page }) => { await page.goto('https://playwright.dev/'); await page.getByRole('link', { name: 'Get started' }).click(); await expect(page.getByRole('heading', { name: 'Installation' })).toBeVisible(); }); ``` **Chain & Filter**: `page.getByRole('listitem').filter({ hasText: 'Item 2' }).getByRole('button').click()` Prefer role + name over CSS/XPath for maintainability. 52

How do I add assertions and handle dynamics?

# Step 4: Assertions Use `expect(locator)` for auto-retrying checks: | Matcher | Example | |---------|---------| | `toBeVisible()` | `await expect(page.getByText('Welcome')).toBeVisible();` | | `toHaveText()` | `await expect(page.locator('h1')).toHaveText('Title');` | | `toBeChecked()` | Checkbox checks | | `toHaveCount(3)` | List length | **Full Example**: ```ts test('assertions', async ({ page }) => { await page.goto('https://playwright.dev/docs'); await expect(page.getByRole('heading', { name: 'Installation' })).toBeVisible(); await expect(page.locator('article')).toHaveCount(5); }); ``` Negate: `.not.toBeVisible()`. Soft: `expect.soft()`. Timeout: `expect.configure({ timeout: 10000 })`. 51

How do I debug, report, and build a mini project?

# Step 5: Debug & Advanced **Debug**: - Inspector: `npx playwright test --debug` - SlowMo: `slowMo: 250` in config - Trace: `npx playwright test --trace on`; view `npx playwright show-trace` - Pause: `await page.pause();` **Mini Project**: Test todo app at https://demo.playwright.dev/todomvc ```ts test('todo app', async ({ page }) => { await page.goto('https://demo.playwright.dev/todomvc'); await page.getByLabel('What needs to be done?').fill('Buy milk'); await page.getByRole('button', { name: 'Add' }).click(); await expect(page.getByLabel('Buy milk')).toBeChecked(false); }); ``` Explore UI Mode, Codegen (`npx playwright codegen`), config.ts for projects.

cd playwright-demo
npm init playwright@latest
```
- Choose TypeScript (recommended), add GitHub Actions workflow, install browsers.
Install Browsers:
```
npx playwright install
```

This scaffolds a project with config, tests folder, and example test.

Why this step matters:

-Establishes a reliable foundation for writing and running tests
-Enables cross-browser testing on Chromium, Firefox, and WebKit immediately

30-60 minutes

Node.js 20+, VS Code, npm/yarn, Terminal

Definition of Done

•Node.js and npm are installed and verified
•Playwright project is initialized with `npm init playwright@latest`

Common Mistakes to Avoid

❌ Using outdated Node.js version

→Install Node.js 20.x or later; check with `node --version`

❌ Skipping browser installation

→Run `npx playwright install` after project setup

❌ Not navigating to project directory
