- This leaves just `recordVideos` and `videoSize` options on the context.
- Videos are saved to `artifactsPath`. We also save their ids to trace.
- `context.close()` waits for the processed videos.
api(trace): introduce artifacts options
This introduces launch({ artifactsPath }) and newContext({ relativeArtifactsPath, recordTrace }) options.
- artifactsPath option controls the directory where all artifacts go. If not passed, artifacts are not collected.
- relativeArtifactsPath can be used to put context-specific artifacts into a subfolder. If not passed, shared artifactsPath is used.
- recordTrace controls trace recording.
We also expose trace types under playwright/types/trace.d.ts.
In the follow up:
- videos will be put into artifactsPath;
- downloads will be put into artifactsPath, or keep using existing downloadsPath when artifactsPath is not specified.
These methods are the only users of waitForNavigation and
waitForLoadState on the server side. This refactor lifts the
Progress wrapper to the top-most goBack/goForward/reload call
and leaves waitForNavigation/waitForLoadState as internal helpers.
This way we get a single Progress for the actual api call.
We now use 'launch' under the hood, which erroneously throws
when 'port' is present.
Instead, moved validation to the client side where it belongs,
added tests for validation errors.
Sometimes, we are unable to take a frame snapshot. The most common
example would be "frame is stuck during the navigation in Chromium",
where we cannot evaluate until the frame is done navigating.
In this case, use all other frames and just stub the failing ones
with "Snapshot is not available". Chances are, noone will even see
this frame because it's an invisible tracking iframe.
- Fill and click actions pass metadata to Progress.
- Progress reports success/failure through instrumentation.
- Tracer consumes ActionResult and ActionMetadata and records them.
Currently, only click and fill actions pass metadata to
contain the size of the change. Everything else should follow.
- Print parentGuid when it is not available for __create__.
Some bots show generic "something is undefined" error - let's
get better information about the failure.
- Ignore events on disposed objects outside of tests.
Some bots show this happening for "previewUpdated" - let's see
whether there are more important events that misbehave.
- We do not need the public BrowserType different from BrowserTypeBase anymore.
- Removing 'logName' parameter from runAbortableTask - it will
be used for metadata instead.
This patch:
- moves ffmpeg binaries from `//bin/` to `//third_party/ffmpeg`
- adds [COPYING.GPLv3](https://github.com/FFmpeg/FFmpeg/blob/master/COPYING.GPLv3)
ffmpeg license
- changes npm packaging to include `//third_party/ffmpeg` only in `playwright` and `playwrihgt-chromium` a
This is an alternative approach to #3698 that was setting up a custom
mapping between chromium revisions and our mirrored builds. For example, we were
taking chromium `792639` and re-packaging it to our CDN as Chromium 1000.
One big downside of this opaque mapping was inability to quickly
understand which Chromium is mirrored to CDN.
To solve this, this patch starts treating browser revision as a fractional number,
with and integer part being a chromium revision, and fractional
part being our build number. For example, we can generate builds `792639`, `792639.1`,
`792639.2` etc, all of which will pick Chromium `792639` and re-package it to our CDN.
In the Playwright code itself, there are a handful of places that treat
browser revision as integer, exclusively to compare revision with some particular
revision numbers. This code would still work as-is, but I changed these places
to use `parseFloat` instead of `parseInt` for correctness.
We used to do fetch() to decode the file buffer. However, this is
blocked by strict CSP policy. Instead, we can use explicit
string -> bytes conversion, and trade performance for CSP compliance.
As discussed offline, our testing scenarios assume running trusted
web content - so this warning is just a noise for this usecases.
When it comes to dealing with untrusted web content though, automation
authors need to make sure to not launch browsers under root in the first
place.
This is a large rework of selectors:
- Each BrowserContext now has a separate Selectors instance that has its own registrations.
Most of them share a single sharedSelectors instance, but contexts created for a connected
browser have their own instance.
- Connected browser now gets a RemoteBrowser object that encapsulates Selectors and Browser.
This Selectors object is registered with the api selectors.
- Public selectors.register api iterates over all registered Selectors channels
and registers in each of them.
- createSelector testing method migrated to ElementHandle._createSelectorForTest.
Sometimes I see "cannot call emit on the undefined" error on the bots.
This change adds some more logging, so we could potentially identify where
the issue comes from.
This introduces basic tracing enabled in our tests.
What is captured:
- network resources;
- snapshots at the start of most actions;
- snapshot after the test failure.
How this integrates with test runner:
- context fixture calls private method context._initSnapshotter() and uses Tracer to trace all events;
- all tests share a single test-results/trace-storage directory to store blobs;
- each test has its own trace file.
- npm run show-trace opens a bare-minimum trace viewer that renders snapshots.
Root index.js is only used for local development, so
assuming dev mode there is fine. This way we do not have
to worry about calling setUnderTest early enough.
One by one seems like a resonable minimum size for clicking.
It is not surprising to see a 1x1 native accessible control
that is covered by a custom control that handles input instead.
Due to wrong type usage, we ignored the origin while granting permissions.
Switching to generated types revealed this issue. We should follow up
with switching all dispatchers to the generated types.
This changes the behavior of slowmo to slow down user actions instead of every protocol command. This makes slowmo a lot more predictable. Without this, there is no way to set slowmo to a good value without incurring a huge delay at the start of your test when it sets things up.
This touches:
- noDefaultViewport;
- ignoreAllDefaultArgs;
- env;
- validateXYZ logic that was copying objects - we do not need that anymore;
- shuffles some converters closer to their usage.
This method waits for visible, hidden, stable or enabled state,
similar to the actionability checks performed before actions.
This gives a bit more control to the user. Some examples:
- Allows to wait for something to be stable before taking a screenshot.
- Allows to wait for the element to be hidden/detached after a specific action.
- Never write to console on the server side - we use stdout for
communication. This includes logPolitely and deprecate.
- Pass undefined instead of null in some BrowserContext methods.
- Use explicit _setFileChooserIntercepted instead of on/off magic.
This migrates Firefox to the protocol-based proxy implementation.
Benefits:
- supports secure web proxies (already supported by Chromium)
- unlocks support for SOCKS proxies with authentication
This starts downloading newer Chromium archives from our CDN, but
retains old endpoint for older Chromium revisions.
This backwards compatibility might help later on to implement
a browser bisecting tool.

Everywhere in our api, possibly missing properties are nullable.
However, to make things easier for everyone, we just default to an
empty url instead, so that users do not have to null-check it.
