This patch starts downloading FFMPEG like we download our browsers
instead of bundling it in the NPM package.
With this patch, NPM size is reduced from 8.8MB to 1.7MB.
Consequences:
- `npx playwright` is drastically faster now
- playwright driver for language bindings is way smaller
- projects that bundle Playwright can pass Apple Notorization
Fixes#5193
- We don't need this, since it should propagate from the main frame.
- Forcing focus in oopif immediately focuses it and blurs currently
focused frame. This leads to undesired side effects, e.g. selects
being closed.
This switches vp8 to "realtime" mode that works fast, adapting to
the speed of incoming frames, and produces the best quality in can
given realtime constraints.
In practice, this gives 2x larger video files but no noticible quality
difference. It also eliminates huge delays for encoding the video.
Drive-by: document our ffmpeg option choices and add some links
to documentation for future use.
This change is adding a new property on the BrowserContextOptions class called `_debugName`. This property allows defining a user-friendly name for the browser context, and currently it is being used in one place, the Trace Viewer. When user provides the new value in the following way:
```typescript
const { chromium } = require('playwright');
(async () => {
const browser = await chromium.launch();
const context = await browser.newContext({ _traceDir: __dirname, _debugName: 'My custom testcase name' });
await context.close();
await browser.close();
})();
```
The `_debugName` will be saved in the `*.trace` file for this browser context, on the `context-created` event, under the key `debugName`.
Later, when such a trace is displayed using Trace Viewer, the `debugName` will be displayed in the dropdown in the top right part of the app instead of the actual trace filename.
Fixes#5157.
- Instead of capturing snapshots on demand, we now stream them
from each frame every 100ms.
- Certain actions can also force snapshots at particular moment using
"checkpoints".
- Trace viewer is able to show the page snapshot at a particular
timestamp, or using a "checkpoint" snapshot.
- Small optimization to not process stylesheets if CSSOM was not used.
There still is a lot of room for improvement.
When `page.reload()` is racing against the renderer-initiated
navigation, we might end up with `waitForNavigation()` being rejected
before the reload implementation is able to catch it.
To avoid that, carefully use Promise.all and await `waitForNavigation`
from the get go.
Same happens to `page.goForward()` and `page.goBack()`.
This changes quoted text selector like `text="Foo Bar"` to perform
normalized whitespace match.
Most of the time users want to match some string visible on the page,
and that always means normalized whitespace.
We keep the case sensitivity and full-string vs substring difference
between quoted and unquoted matches.
This adds `{Page,Frame}.isChecked(selector)` and `ElementHandle.isChecked()` methods.
Useful to do assertions in tests:
```js
await page.click('text="Add TODO"');
expect(await page.isChecked('.item-done')).toBe(false);
```
These methods are useful for verification in tests, e.g.
```js
expect(await page.isEnabled(':text("Remove All")')).toBe(false);
await page.click(':text("Add Item")');
expect(await page.isVisible('.item:text("new item")')).toBe(true);
expect(await page.isEnabled(':text("Remove All")')).toBe(true);
```
When element with position:sticky covers some part of
the scroll container, we could fail to scroll from under it
to perform an action. To fight this, we can try different
scroll alignments and scroll to the top/bottom/center
in the attempt to scroll away from sticky header/footer/sidebar.
Windows 7 was end-of-lifed on January 14, 2020. We don't support this
system, but we'd like to have a best-effort to work there.
It does look like Chromium is missing some libraries on Win 7, however
it still manages to work there. To support this usecase, this patch
starts printing console warning about missing libraries on Win 7 only
instead of refusing to launch.
Fixes#3496
We now default to `text` that does substring case-insensitive match
with normalized whitespace. `text-is` matches the whole string.
`matches-text` is renamed to `text-matches`.
When parsing CSS, we assume everything is a valid CSS function,
unless it is in the list of custom functions. This way we'll parse
future CSS functions automatically.
