v1.23.0
Highlights
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 = browser.new_context(record_har_path="github.har.zip")
# ... do stuff ...
context.close()
Use the new methods method: Page.route_from_har
or method: BrowserContext.route_from_har
to serve matching responses from the HAR file:
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
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.route_from_har
or method: BrowserContext.route_from_har
also participate in routing and could be deferred to.
Web-First Assertions Update
- New method
method: LocatorAssertions.to_have_values
that asserts all selected values of<select multiple>
element. - Methods
method: LocatorAssertions.to_contain_text
andmethod: LocatorAssertions.to_have_text
now acceptignore_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 = browser.new_context(service_workers="block") page = context.new_page()
-
Using
.zip
path forrecordHar
context option automatically zips the resulting HAR: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 = browser.new_context(record_har_mode="minimal", record_har_path="har.har")

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