This saves some CPU cycles while waiting for the page to
change the state, e.g. for animations to complete.
Note that retrying logic is only applicable in rare
circumstances like unexpected scroll in the middle of an
action, or some overlay blocking the click. Usually,
action times out in this cases while retrying.
We currently spawn a process per page when recording
video in Chromium. This triggers "too many listeners" on the
process object once you have enough pages open.
- 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.
- 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.
- 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
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.
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.
This touches:
- noDefaultViewport;
- ignoreAllDefaultArgs;
- env;
- validateXYZ logic that was copying objects - we do not need that anymore;
- shuffles some converters closer to their usage.
- 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
Make sure executable exists before launching it. If it doesn't and
we were launched without custom executable path, print a helpful
instruction to run `npm i playwright` and get browsers downloaded.
Note: there's already a test that makes sure bad executable paths
are treated fairly: 9132d23b2b/test/launcher.jest.js (L54-L59)
This doesn't test missing default browser installation which I think is
fine.
Fixes#3161
WebKit WPE assumes `libglesv2.so` is available on the host system
and uses `dlopen` to open it.
This patch starts using `ldconfig -p` to check if the library
exists on the system.
