Instead of filtering the whole trace file on export, we write
into separate trace file for each chunk. We also write a separate
trace.network file with all resources, because it is reused between
chunks.
This brings us towards `tracing.startFile()/stopFile()` api.
fix(test runner): avoid internal error for step end without begin
Consider the following scenario:
- Test finishes and starts tearing down fixtures.
- Fixture teardown starts a step S and then times out.
- We declare the test finished (with timeout).
- Dispatcher shuts down the worker and spins a new one for a retry.
Additionally, it clears steps information for the test to be
ready for the new retry. Step S information is lost.
- Meanwhile, during worker teardown, the step S does
actually finish (usually with an error), and we send stepEnd for S.
- Dispatcher does not know what to do with step S end and
prints an internal error.
The fix is to ignore certain messages from the shutting down worker that failed.
When browser receives multiple header values for the same header name,
we present them as LF-separated value. This is not considered valid in
Node, so we should split by LF when serving a snapshot.
There more invalid characters in headers, so just in case we try/catch it.
- Simplify by only considering client/ vs non-client/
- Fix stack traces when calling from other playwright code, e.g. from the cli
- Account for re-entrant calls that happen when
instrumenting context creation/desctruction
- Add tests
- Fix StackTraceView on Windows
When sharing a context between tests and using `'on-first-retry'` we
could end up with tracing still running in non-retried tests. That's
extra overhead without a reason.
Without this, Playwright's CDP feature leaves unreachable
targets (namely OOPIFs).
This change allows for more advanced experimentation in user-land
without relying on out-of-band CDP connections and clients.
Now you can, for example, call `DOM.getDocument` on the
page OR main frame, observe there is an iframe node with
no `contentDocument` (i.e. OOPIF), make note of the referenced
`frameId`, and then iterate of page.frames() calling `Target.getInfo`
on each to link the Playwright Frame with the CDP `frameId` and
then recurse.

Using a worker fixture forces a new worker. This might be unexpected
when part of the test file runs in one worker, and another runs
in another worker. Top-level use of worker fixtures is still fine.
- Uses some auto fixtures to set default options and instrumentation on BrowserType.
- Moves screenshot, trace and video to worker-scoped fixtures.
- Throws in page/context when used from beforeAll/afterAll.
- Plumbs around BrowserType to be accessible from Browser and BrowserContext.
Each hook gets its own test scope. This is not too useful for
object fixtures like `page` (although one can use a page in
`beforeAll` to save storage state), but much more useful for option
fixtures like `viewport`.
This patch adds support for the `vue` selector engine that allows
selecting DOM elements based on the component name.
> **NOTE**: `vue` engine supports Vue2 and Vue2.

This patch adds support for the `react` selector engine that allows
selecting DOM elements based on the component name.
> **NOTE**: in case of multi-root components (React.Fragment), `react`
engine will select all root DOM elements.
> **NOTE**: `react` engine supports react v15+.

Subsequent invocations reset the trace. This removes the `tracing._reset` method.
Also fixed a bug where BASE element was not reset properly.
Also fixed a bug where tracing would affect the result of protocol call
by setting `callMetadata.error` property.
`tracing._export({ path })` exports current tracing state into a file
and does not require tracing to be stopped.
`tracing._reset()` resets current tracing state, but keeps resources
around so they can be referenced in the future snapshots. Does not stop.
The usage pattern is:
```js
await tracing.start({ screenshots: true, snapshots: true });
// ...
await tracing._reset();
// Do stuff, it will all be in the export below.
await tracing._export({ path });
// ...
await tracing.stop();
```
