- Intercept CSSOM modifications and recalculate overridden css text.
- When css text does not change, use "backwards reference" similar
to node references.
- Set 'Cache-Control: no-cache' for resources that could be overridden.
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.
This introduces an http server that serves our frontend and our snapshots. There is more work to untangle the big server into a few modules.
This change allows us:
- Maybe eventually serve the trace viewer as a web page.
- Rely on browser caches for fast snapshot rendering. This PR also adds "snapshot on hover" feature, subject to change.
feat(trace viewer): Extending existing NetworkTab view
Currently the network tab contains a limited amount of information on the resources that were loaded in the browser. This change proposes extending the details displayed for each resource, to include:
- HTTP method,
- Full url,
- Easily visible response content type,
- Request headers,
- Request & response bodies.
Such level of information could help quickly understand what happened in the application, when it was communicating with backend services. This can help debug tests quicker to figure out why they are failing.
This implementation still needs some clean up & tests improvement, but I wanted to propose such changes and gather your feedback before going too far.
- 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()`.
Folio 0.3.17 doesn't differentiate between expected and unexpected
flakiness, thus no longer supporting the "flaky" annotation.
Flaky specs are reported after run, but flaky specs do not render
test run as failed. We'll track flakiness separately via a dashboard.
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.
Tests were waiting for `framesent` event after awaiting `page.evaluate`.
Sometimes, `page.evaluate` took long enough and finished after
the `framesent`.
Drive-by: small fixes for mode=service test fixture.
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.
