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()`.
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.
Pre-BigSur, MacOS updates were labeled as "minor" releases, so we had
to bake separate builds for different 10.X releases.
In BigSur era, it doesn't seem to be the case, so for now we can re-use
our BigSur builds across all BigSur versions (11.0, 11.1 and 11.2).
If we ever need to have a custom build for some bigsur minor version,
e.g. `11.6`, we'll have a new browser platform along with generic
`mac11` platform.
Fixes#4775.
fix(trace viewer): updating default traceStorageDir value
When `npx playwright show-trace <tracePath>` command is executed, without providing the `resources` optional parameter, the function expected the `traceStorageDir` default value to be the same directory as in which the tracePath resides. This change updates it to the `dirname(tracePath)/trace-resources` if it exists. Such a directory hirerachy is the default that is created when running the tracer in Playwright.
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);
```
- Allow specifying which browsers to install. This comes handy in playwright-cli.
- Print "npx playwright" as a tool name in help messages, instead of "cli".
