Version 1.26

Assertions

New option enabled for [method: LocatorAssertions.toBeEnabled].
[method: LocatorAssertions.toHaveText] now pierces open shadow roots.
New option editable for [method: LocatorAssertions.toBeEditable].
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

Highlights

Version 1.18

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.

WebKit 15.4

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.

Ubuntu ARM64 support + more

Playwright now supports Ubuntu 20.04 ARM64. You can now run Playwright tests inside Docker on Apple M1 and on Raspberry Pi.
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].

Docker support for Arm64

Version 1.15

🖱️ Mouse Wheel

By using Page.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:

Request.all_headers()
Request.headers_array()
Request.header_value(name: str)
Response.all_headers()
Response.headers_array()
Response.header_value(name: str)
Response.header_values(name: str)

🌈 Forced-Colors emulation

Its now possible to emulate the forced-colors CSS media feature by passing it in the context options or calling Page.emulate_media().

New APIs

Page.route() accepts new times option to specify how many times this route should be matched.
Page.set_checked(selector: str, checked: bool) and Locator.set_checked(selector: str, checked: bool) was introduced to set the checked state of a checkbox.
Request.sizes() Returns resource size information for given http request.
BrowserContext.tracing.start_chunk() - Start a new trace chunk.
BrowserContext.tracing.stop_chunk() - Stops a new trace chunk.

Browser Versions

Chromium 96.0.4641.0
Mozilla Firefox 92.0
WebKit 15.0

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:
