Version 1.52

Highlights

New method [method: LocatorAssertions.toContainClass] to ergonomically assert individual class names on the element.
```
  expect(page.get_by_role('listitem', name='Ship v1.52')).to_contain_class('done')
```

Aria Snapshots got two new properties: /children for strict matching and /url for links.

expect(locator).to_match_aria_snapshot("""
  - list
    - /children: equal
    - listitem: Feature A
    - listitem:
      - link "Feature B":
        - /url: "https://playwright.dev"
""")

Miscellaneous

New option [option: APIRequest.newContext.maxRedirects] in [method: APIRequest.newContext] to control the maximum number of redirects.
New option [option: Locator.ariaSnapshot.ref] in [method: Locator.ariaSnapshot] to generate reference for each element in the snapshot which can later be used to locate the element.
HTML reporter now supports NOT filtering via !@my-tag or !my-file.spec.ts or !p:my-project.

Breaking Changes

Base URL matching is not supported in [method: Page.frame] anymore. We recommend migrating to [method: Page.frameLocator] instead for having a more convenient API.
Glob URL patterns in methods like [method: Page.route] do not support ? and [] anymore. We recommend using regular expressions instead.
Method [method: Route.continue] does not allow to override the Cookie header anymore. If a Cookie header is provided, it will be ignored, and the cookie will be loaded from the browser's cookie store. To set custom cookies, use [method: BrowserContext.addCookies].
macOS 13 is now deprecated and will no longer receive WebKit updates. Please upgrade to a more recent macOS version to continue benefiting from the latest WebKit improvements.

Version 1.51

Highlights

New option [option: BrowserContext.storageState.indexedDB] for [method: BrowserContext.storageState] allows to save and restore IndexedDB contents. Useful when your application uses IndexedDB API to store authentication tokens, like Firebase Authentication.

Here is an example following the authentication guide:
```
# Save storage state into the file. Make sure to include IndexedDB.
storage = await context.storage_state(path="state.json", indexed_db=True)

# Create a new context with the saved storage state.
context = await browser.new_context(storage_state="state.json")
```

New option [option: Locator.filter.visible] for [method: Locator.filter] allows matching only visible elements.

# Ignore invisible todo items.
todo_items = page.get_by_test_id("todo-item").filter(visible=True)
# Check there are exactly 3 visible ones.
await expect(todo_items).to_have_count(3)

New option contrast for methods [method: Page.emulateMedia] and [method: Browser.newContext] allows to emulate the prefers-contrast media feature.
New option [option: APIRequest.newContext.failOnStatusCode] makes all fetch requests made through the [APIRequestContext] throw on response codes other than 2xx and 3xx.

Miscellaneous

Added method [method: LocatorAssertions.toHaveAccessibleErrorMessage] to assert the Locator points to an element with a given aria errormessage.

UI updates

New button in Codegen for picking elements to produce aria snapshots.
Additional details (such as keys pressed) are now displayed alongside action API calls in traces.
Display of canvas content in traces is error-prone. Display is now disabled by default, and can be enabled via the Display canvas content UI setting.
Call and Network panels now display additional time information.

Breaking

[method: LocatorAssertions.toBeEditable] and [method: Locator.isEditable] now throw if the target element is not <input>, <select>, or a number of other editable elements.

Version 1.49

Aria snapshots

New assertion [method: LocatorAssertions.toMatchAriaSnapshot] verifies page structure by comparing to an expected accessibility tree, represented as YAML.

page.goto("https://playwright.dev")
expect(page.locator('body')).to_match_aria_snapshot('''
  - banner:
    - heading /Playwright enables reliable/ [level=1]
    - link "Get started"
    - link "Star microsoft/playwright on GitHub"
  - main:
    - img "Browsers (Chromium, Firefox, WebKit)"
    - heading "Any browser • Any platform • One API"
''')

You can generate this assertion with Test Generator or by calling [method: Locator.ariaSnapshot].

Learn more in the aria snapshots guide.

Tracing groups

New method [method: Tracing.group] allows you to visually group actions in the trace viewer.

# All actions between group and group_end
# will be shown in the trace viewer as a group.
page.context.tracing.group("Open Playwright.dev > API")
page.goto("https://playwright.dev/")
page.get_by_role("link", name="API").click()
page.context.tracing.group_end()

Breaking: `chrome` and `msedge` channels switch to new headless mode

This change affects you if you're using one of the following channels in your playwright.config.ts:

chrome, chrome-dev, chrome-beta, or chrome-canary
msedge, msedge-dev, msedge-beta, or msedge-canary

After updating to Playwright v1.49, run your test suite. If it still passes, you're good to go. If not, you will probably need to update your snapshots, and adapt some of your test code around PDF viewers and extensions. See issue #33566 for more details.

Try new Chromium headless

You can opt into the new headless mode by using 'chromium' channel. As official Chrome documentation puts it:

New Headless on the other hand is the real Chrome browser, and is thus more authentic, reliable, and offers more features. This makes it more suitable for high-accuracy end-to-end web app testing or browser extension testing.

See issue #33566 for the list of possible breakages you could encounter and more details on Chromium headless. Please file an issue if you see any problems after opting in.

pytest test_login.py --browser-channel chromium

Miscellaneous

There will be no more updates for WebKit on Ubuntu 20.04 and Debian 11. We recommend updating your OS to a later version.

WebSocket routing

New methods [method: Page.routeWebSocket] and [method: BrowserContext.routeWebSocket] allow to intercept, modify and mock WebSocket connections initiated in the page. Below is a simple example that mocks WebSocket communication by responding to a "request" with a "response".

def message_handler(ws: WebSocketRoute, message: Union[str, bytes]):
  if message == "request":
    ws.send("response")

page.route_web_socket("/ws", lambda ws: ws.on_message(
    lambda message: message_handler(ws, message)
))

See [WebSocketRoute] for more details.

UI updates

New "copy" buttons for annotations and test location in the HTML report.
Route method calls like [method: Route.fulfill] are not shown in the report and trace viewer anymore. You can see which network requests were routed in the network tab instead.
New "Copy as cURL" and "Copy as fetch" buttons for requests in the network tab.

Miscellaneous

New method [method: Page.requestGC] may help detect memory leaks.
Requests made by [APIRequestContext] now record detailed timing and security information in the HAR.

preview of font assets

Miscellaneous

The mcr.microsoft.com/playwright/python:v1.47.0 now serves a Playwright image based on Ubuntu 24.04 Noble. To use the 22.04 jammy-based image, please use mcr.microsoft.com/playwright/python:v1.47.0-jammy instead.
The :latest/:focal/:jammy tag for Playwright Docker images is no longer being published. Pin to a specific version for better stability and reproducibility.
TLS client certificates can now be passed from memory by passing [option: Browser.newContext.clientCertificates.cert] and [option: Browser.newContext.clientCertificates.key] as bytes instead of file paths.
[option: Locator.selectOption.noWaitAfter] in [method: Locator.selectOption] was deprecated.

TLS Client Certificates

Playwright now allows to supply client-side certificates, so that server can verify them, as specified by TLS Client Authentication.

You can provide client certificates as a parameter of [method: Browser.newContext] and [method: APIRequest.newContext]. The following snippet sets up a client certificate for https://example.com:

context = browser.new_context(
    client_certificates=[
        {
            "origin": "https://example.com",
            "certPath": "client-certificates/cert.pem",

Clock

Utilizing the new [Clock] API allows to manipulate and control time within tests to verify time-related behavior. This API covers many common scenarios, including:

testing with predefined time;
keeping consistent time and timers;
monitoring inactivity;
ticking through time manually.

# Initialize clock with some time before the test time and let the page load
# naturally. `Date.now` will progress as the timers fire.
page.clock.install(time=datetime.datetime(2024, 2, 2, 8, 0, 0))
page.goto("http://localhost:3333")

# Pretend that the user closed the laptop lid and opened it again at 10am.
# Pause the time once reached that point.
page.clock.pause_at(datetime.datetime(2024, 2, 2, 10, 0, 0))

# Assert the page state.
expect(page.get_by_test_id("current-time")).to_have_text("2/2/2024, 10:00:00 AM")

# Close the laptop lid again and open it at 10:30am.
page.clock.fast_forward("30:00")
expect(page.get_by_test_id("current-time")).to_have_text("2/2/2024, 10:30:00 AM")

See the clock guide for more details.

Miscellaneous

Method [method: Locator.setInputFiles] now supports uploading a directory for <input type=file webkitdirectory> elements.
```
page.get_by_label("Upload directory").set_input_files('mydir')
```
Multiple methods like [method: Locator.click] or [method: Locator.press] now support a ControlOrMeta modifier key. This key maps to Meta on macOS and maps to Control on Windows and Linux.
```
# Press the common keyboard shortcut Control+S or Meta+S to trigger a "Save" operation.
page.keyboard.press("ControlOrMeta+S")
```
New property httpCredentials.send in [method: APIRequest.newContext] that allows to either always send the Authorization header or only send it in response to 401 Unauthorized.
Playwright now supports Chromium, Firefox and WebKit on Ubuntu 24.04.
v1.45 is the last release to receive WebKit update for macOS 12 Monterey. Please update macOS to keep using the latest WebKit.

Accessibility assertions

[method: LocatorAssertions.toHaveAccessibleName] checks if the element has the specified accessible name:
```
locator = page.get_by_role("button")
expect(locator).to_have_accessible_name("Submit")
```
[method: LocatorAssertions.toHaveAccessibleDescription] checks if the element has the specified accessible description:
```
locator = page.get_by_role("button")
expect(locator).to_have_accessible_description("Upload a photo")
```
[method: LocatorAssertions.toHaveRole] checks if the element has the specified ARIA role:
```
locator = page.get_by_test_id("save-button")
expect(locator).to_have_role("button")
```

Locator handler

After executing the handler added with [method: Page.addLocatorHandler], Playwright will now wait until the overlay that triggered the handler is not visible anymore. You can opt-out of this behavior with the new no_wait_after option.
You can use new times option in [method: Page.addLocatorHandler] to specify maximum number of times the handler should be run.
The handler in [method: Page.addLocatorHandler] now accepts the locator as argument.
New [method: Page.removeLocatorHandler] method for removing previously added locator handlers.

locator = page.get_by_text("This interstitial covers the button")
page.add_locator_handler(locator, lambda overlay: overlay.locator("#close").click(), times=3, no_wait_after=True)
# Run your tests that can be interrupted by the overlay.
# ...
page.remove_locator_handler(locator)

```
locator = page.locator("iframe[name='embedded']")
# ...
frame_locator = locator.content_frame
frame_locator.getByRole("button").click()
```
New method [method: FrameLocator.owner] converts a [FrameLocator] object to a [Locator]. This can be useful when you have a [FrameLocator] object obtained somewhere, and later on would like to interact with the iframe element.
```
frame_locator = page.frame_locator("iframe[name='embedded']")
# ...
locator = frame_locator.owner
expect(locator).to_be_visible()

New Locator Handler

New method [method: Page.addLocatorHandler] registers a callback that will be invoked when specified element becomes visible and may block Playwright actions. The callback can get rid of the overlay. Here is an example that closes a cookie dialog when it appears.

# Setup the handler.
page.add_locator_handler(
    page.get_by_role("heading", name="Hej! You are in control of your cookies."),
    lambda: page.get_by_role("button", name="Accept all").click(),
)
# Write the test as usual.

Locators Update

Use [method: Locator.or] to create a locator that matches either of the two locators. Consider a scenario where you'd like to click on a "New email" button, but sometimes a security settings dialog shows up instead. In this case, you can wait for either a "New email" button, or a dialog and act accordingly:
```
new_email = page.get_by_role("button", name="New email")
dialog = page.get_by_text("Confirm security settings")
expect(new_email.or_(dialog)).is_visible()
if (dialog.is_visible()):
  page.get_by_role("button", name="Dismiss").click()
new_email.click()
```

Use new options [option: Locator.filter.hasNot] and [option: Locator.filter.hasNotText] in [method: Locator.filter] to find elements that do not match certain conditions.

row_locator = page.locator("tr")
row_locator.filter(has_not_text="text in column 1").filter(
    has_not=page.get_by_role("button", name="column 2 button")
).screenshot()

Use new web-first assertion [method: LocatorAssertions.toBeAttached] to ensure that the element is present in the page's DOM. Do not confuse with the [method: LocatorAssertions.toBeVisible] that ensures that element is both attached & visible.

New APIs

[method: Locator.or]

Version 1.27

Locators

With these new APIs writing locators is a joy:

[method: Page.getByText] to locate by text content.
[method: Page.getByRole] to locate by ARIA role, ARIA attributes and accessible name.
[method: Page.getByLabel] to locate a form control by associated label's text.
[method: Page.getByTestId] to locate an element based on its data-testid attribute (other attribute can be configured).
[method: Page.getByPlaceholder] to locate an input by placeholder.
[method: Page.getByAltText] to locate an element, usually image, by its text alternative.
[method: Page.getByTitle] to locate an element by its title.

page.get_by_label("User Name").fill("John")

page.get_by_label("Password").fill("secret-password")

page.get_by_role("button", name="Sign in").click()

expect(page.get_by_text("Welcome, John!")).to_be_visible()

All the same methods are also available on [Locator], [FrameLocator] and [Frame] classes.

Other highlights

As announced in v1.25, Ubuntu 18 will not be supported as of Dec 2022. In addition to that, there will be no WebKit updates on Ubuntu 18 starting from the next Playwright release.

Behavior Changes

[method: LocatorAssertions.toHaveAttribute] with an empty value does not match missing attribute anymore. For example, the following snippet will succeed when button does not have a disabled attribute.
```
expect(page.get_by_role("button")).to_have_attribute("disabled", "")
```

New option visible for [method: LocatorAssertions.toBeVisible].

Other highlights

New option max_redirects for [method: APIRequestContext.get] and others to limit redirect count.
Python 3.11 is now supported.

Behavior Change

A bunch of Playwright APIs already support the wait_until: "domcontentloaded" option. For example:

page.goto("https://playwright.dev", wait_until="domcontentloaded")

Prior to 1.26, this would wait for all iframes to fire the DOMContentLoaded event.

To align with web specification, the 'domcontentloaded' value only waits for the target frame to fire the 'DOMContentLoaded' event. Use wait_until="load" to wait for all iframes.

New introduction docs

We rewrote our Getting Started docs to be more end-to-end testing focused. Check them out on playwright.dev.

Version 1.23

Network Replay

Now you can record network traffic into a HAR file and re-use this traffic in your tests.

To record network into HAR file:

npx playwright open --save-har=github.har.zip https://github.com/microsoft

Alternatively, you can record HAR programmatically:

context = await browser.new_context(record_har_path="github.har.zip")
# ... do stuff ...
await context.close()

context = browser.new_context(record_har_path="github.har.zip")
# ... do stuff ...
context.close()

Use the new methods [method: Page.routeFromHAR] or [method: BrowserContext.routeFromHAR] to serve matching responses from the HAR file:

await context.route_from_har("github.har.zip")

context.route_from_har("github.har.zip")

Read more in our documentation.

Advanced Routing

You can now use [method: Route.fallback] to defer routing to other handlers.

Consider the following example:

# Remove a header from all requests
async def remove_header_handler(route: Route) -> None:
    headers = await route.request.all_headers()
    if "if-none-match" in headers:
        del headers["if-none-match"]
    await route.fallback(headers=headers)

await page.route("**/*", remove_header_handler)

# Abort all images
async def abort_images_handler(route: Route) -> None:
    if route.request.resource_type == "image":
        await route.abort()
    else:
        await route.fallback()

await page.route("**/*", abort_images_handler)

# Remove a header from all requests
def remove_header_handler(route: Route) -> None:
    headers = route.request.all_headers()
    if "if-none-match" in headers:
        del headers["if-none-match"]
    route.fallback(headers=headers)

page.route("**/*", remove_header_handler)

# Abort all images
def abort_images_handler(route: Route) -> None:
    if route.request.resource_type == "image":
        route.abort()
    else:
        route.fallback()

page.route("**/*", abort_images_handler)

Note that the new methods [method: Page.routeFromHAR] and [method: BrowserContext.routeFromHAR] also participate in routing and could be deferred to.

Web-First Assertions Update

New method [method: LocatorAssertions.toHaveValues] that asserts all selected values of <select multiple> element.
Methods [method: LocatorAssertions.toContainText] and [method: LocatorAssertions.toHaveText] now accept ignore_case option.

Miscellaneous

If there's a service worker that's in your way, you can now easily disable it with a new context option service_workers:

context = await browser.new_context(service_workers="block")
page = await context.new_page()

context = browser.new_context(service_workers="block")
page = context.new_page()

Using .zip path for recordHar context option automatically zips the resulting HAR:

context = await browser.new_context(record_har_path="github.har.zip")

context = browser.new_context(record_har_path="github.har.zip")

If you intend to edit HAR by hand, consider using the "minimal" HAR recording mode that only records information that is essential for replaying:

context = await browser.new_context(record_har_mode="minimal", record_har_path="har.har")

context = browser.new_context(record_har_mode="minimal", record_har_path="har.har")

Playwright now runs on Ubuntu 22 amd64 and Ubuntu 22 arm64.

Version 1.22

New [method: Locator.filter] API to filter an existing locator

buttons = page.locator("role=button")
# ...
submit_button = buttons.filter(has_text="Submit")
submit_button.click()

API Testing

Playwright for Python 1.18 introduces new API Testing that lets you send requests to the server directly from Python! Now you can:

test your server API
prepare server side state before visiting the web application in a test
validate server side post-conditions after running some actions in the browser

To do a request on behalf of Playwright's Page, use new [property: Page.request] API:

# Do a GET request on behalf of page
res = await page.request.get("http://example.com/foo.json")

# Do a GET request on behalf of page
res = page.request.get("http://example.com/foo.json")

Read more in our documentation.

Web-First Assertions

Playwright for Python 1.18 introduces Web-First Assertions.

Consider the following example:

from playwright.async_api import Page, expect

async def test_status_becomes_submitted(page: Page) -> None:
    # ..
    await page.locator("#submit-button").click()
    await expect(page.locator(".status")).to_have_text("Submitted")

from playwright.sync_api import Page, expect

def test_status_becomes_submitted(page: Page) -> None:
    # ..
    page.locator("#submit-button").click()
    expect(page.locator(".status")).to_have_text("Submitted")

Playwright will be re-testing the node with the selector .status until fetched Node has the "Submitted" text. It will be re-fetching the node and checking it over and over, until the condition is met or until the timeout is reached. You can pass this timeout as an option.

Read more in our documentation.

Locator Improvements

[method: Locator.dragTo]

Each locator can now be optionally filtered by the text it contains:

await page.locator("li", has_text="my item").locator("button").click()

page.locator("li", has_text="my item").locator("button").click()

New APIs & changes

accept_downloads option now defaults to True.
sources option to embed sources into traces.

This version was also tested against the following stable channels:

Google Chrome 97
Microsoft Edge 97

Version 1.17

Frame Locators

Playwright 1.17 introduces frame locators - a locator to the iframe on the page. Frame locators capture the logic sufficient to retrieve the iframe and then locate elements in that iframe. Frame locators are strict by default, will wait for iframe to appear and can be used in Web-First assertions.

Frame locators can be created with either [method: Page.frameLocator] or [method: Locator.frameLocator] method.

locator = page.frame_locator("my-frame").locator("text=Submit")
locator.click()

Trace Viewer Update

Playwright Trace Viewer is now available online at https://trace.playwright.dev! Just drag-and-drop your trace.zip file to inspect its contents.

NOTE: trace files are not uploaded anywhere; trace.playwright.dev is a progressive web application that processes traces locally.

Playwright Test traces now include sources by default (these could be turned off with tracing option)
Trace Viewer now shows test name
New trace metadata tab with browser details
Snapshots now have URL bar

HTML Report Update

HTML report now supports dynamic filtering
Report is now a single static HTML file that could be sent by e-mail or as a slack attachment.

You can now use Playwright to install stable version of Edge on Linux:
```
npx playwright install msedge
```

New APIs

Tracing now supports a 'title' option
Page navigations support a new 'commit' waiting option

Version 1.16

🎭 Playwright Library

`locator.wait_for`

Wait for a locator to resolve to a single element with a given state. Defaults to the state: 'visible'.

Comes especially handy when working with lists:

order_sent = page.locator("#order-sent")
order_sent.wait_for()

Read more about [method: Locator.waitFor].

🖱️ Mouse Wheel

By using [method: Mouse.wheel] you are now able to scroll vertically or horizontally.

📜 New Headers API

Previously it was not possible to get multiple header values of a response. This is now possible and additional helper functions are available:

[method: Request.allHeaders]
[method: Request.headersArray]
[method: Request.headerValue]
[method: Response.allHeaders]
[method: Response.headersArray]
[method: Response.headerValue]
[method: Response.headerValues]

🌈 Forced-Colors emulation

Its now possible to emulate the forced-colors CSS media feature by passing it in the [method: Browser.newContext] or calling [method: Page.emulateMedia].

New APIs

[method: Page.route] accepts new times option to specify how many times this route should be matched.
[method: Page.setChecked] and [method: Locator.setChecked] were introduced to set the checked state of a checkbox.
[method: Request.sizes] Returns resource size information for given http request.
[method: Tracing.startChunk] - Start a new trace chunk.
[method: Tracing.stopChunk] - Stops a new trace chunk.

Browser Versions

Version 1.14

⚡️ New "strict" mode

Selector ambiguity is a common problem in automation testing. "strict" mode ensures that your selector points to a single element and throws otherwise.

Pass strict=true into your action calls to opt in.

# This will throw if you have more than one button!
page.click("button", strict=True)

📍 New Locators API

Locator represents a view to the element(s) on the page. It captures the logic sufficient to retrieve the element at any given moment.

The difference between the Locator and ElementHandle is that the latter points to a particular element, while Locator captures the logic of how to retrieve that element.

Also, locators are "strict" by default!

locator = page.locator("button")
locator.click()

Learn more in the documentation.

🧩 Experimental React and Vue selector engines

React and Vue selectors allow selecting elements by its component name and/or property values. The syntax is very similar to attribute selectors and supports all attribute selector operators.

page.locator("_react=SubmitButton[enabled=true]").click()
page.locator("_vue=submit-button[enabled=true]").click()

Learn more in the react selectors documentation and the vue selectors documentation.

✨ New `nth` and `visible` selector engines

nth selector engine is equivalent to the :nth-match pseudo class, but could be combined with other selector engines.
visible selector engine is equivalent to the :visible pseudo class, but could be combined with other selector engines.

# select the first button among all buttons
button.click("button >> nth=0")
# or if you are using locators, you can use first, nth() and last
page.locator("button").first.click()

# click a visible button
button.click("button >> visible=true")

🧟‍♂️ Introducing Playwright Trace Viewer

Playwright Trace Viewer is a new GUI tool that helps exploring recorded Playwright traces after the script ran. Playwright traces let you examine:

page DOM before and after each Playwright action
page rendering before and after each Playwright action
browser network during script execution

Traces are recorded using the new [property: BrowserContext.tracing] API:

browser = chromium.launch()
context = browser.new_context()

# Start tracing before creating / navigating a page.
context.tracing.start(screenshots=True, snapshots=True)

page.goto("https://playwright.dev")

# Stop tracing and export it into a zip archive.
context.tracing.stop(path = "trace.zip")

Traces are examined later with the Playwright CLI:

playwright show-trace trace.zip

That will open the following GUI:
