test('should login successfully with valid credentials', async ({ page }) => {
await page.getByLabel('Email').fill('user@example.com');
await page.getByLabel('Password').fill('password123');
await page.getByRole('button', { name: 'Sign In' }).click();
await expect(page.getByRole('heading', { name: 'Dashboard' })).toBeVisible();
});
});
## Locator Strategy
### Recommended Locators
- `page.getByRole()` - Best for accessibility and user perspective
- `page.getByLabel()` - For form inputs with labels
- `page.getByText()` - For elements with visible text
- `page.getByTestId()` - When `data-testid` attributes exist
- `page.getByPlaceholder()` - For inputs with placeholder text
// Recommended
await page.getByRole('button', { name: 'Submit' }).click();
await page.getByLabel('Email address').fill('test@example.com');
// Avoid
await page.locator('.btn-primary').click();
## Assertions and Waits
### Web-First Assertions
Prefer web-first assertions that automatically wait and retry:
- `toBeVisible()` - Element is visible
- `toHaveText()` - Element has specific text
- `toHaveValue()` - Input has specific value
- `toHaveURL()` - Page URL assertion
// Recommended - web-first assertions
await expect(page.getByRole('alert')).toBeVisible();
await expect(page).toHaveURL('/dashboard');
// Avoid - hardcoded timeouts
await page.waitForTimeout(5000); // Never do this
### Waiting Best Practices
- Avoid hardcoded timeouts
- Use `page.waitForLoadState()` for navigation
- Use `page.waitForResponse()` for API calls
