#1 Auto Waiting

Playwright waits automatically before acting.

await page.getByRole('button',{name:'Login'}).click();

#2 Locator Re-Evaluation

Playwright finds elements again when needed.

const btn=page.getByRole('button',{name:'Login'});

#3 Web First Assertions

Assertions keep checking until condition is met.

await expect(page.getByText('Success')).toBeVisible();

#4 Browser Context

Multiple isolated users in one browser.

const context=await browser.newContext();

#5 Storage State

Reuse login sessions.

await context.storageState({path:'auth.json'});

#6 Trace Viewer

Video-like debugging for tests.

await context.tracing.start();

#7 Network Mocking

Control backend responses.

await page.route('**/users',route=>route.fulfill());

#8 API Testing

Test APIs without browser.

await request.get('/users');

#9 Parallel Execution

Run tests faster.

workers:4

#10 Retries

Reduce intermittent failures.

retries:2

#11 Projects

Run in multiple browsers.

projects:[{name:'chrome'}]

#12 Soft Assertions

Continue even after assertion failure.

expect.soft(locator).toBeVisible();

#13 Shadow DOM

Handle web components easily.

page.locator('custom-element')

#14 Accessibility Testing

Use semantic locators.

page.getByRole('button')

#15 HAR Recording

Capture network traffic.

recordHar:{path:'network.har'}
