Adds a buffer mode that can be toggled by pressing <kbd>b</kbd>. When
engaged, changed test files are collected and shown on screen. The test
run is then kicked off by pressing <kbd>Enter</kbd>.
This changes the signal to start a test run from <kbd>Cmd+s</kbd> to a
<kbd>Enter</kbd> press in the test terminal. It should help users with
auto-save and make it easier to run on long-running tests. It feels very
similar to running `npx playwright test`, but without having to write a
filter.

This PR rewrites `watchMode.ts` to use `TestServer` under the hood. It's
essentially a complete rewrite, so don't pay too much attention on the
old implementation. Note that there's no changes to tests, so all
behaviour we have specced out there still works.
To make this work without a superfluous WebSocket connection, I had to
refactor `TestServerConnection` a little. Originally, I pulled this into
a [separate PR](https://github.com/microsoft/playwright/pull/32132), but
then realised how small the refactoring is. So it's in this PR now. Let
me know if you'd like to land it separately.
Introduces an `--only-changed [base ref]` option.
`playwright test --only-changed` filters the test run to only run test
suites that have uncommitted changes.
`playwright test --only-changed=foo` runs only tests that were changed
since commit `foo`.
In pull request CI, this can be used to run changed tests first and fail
fast: `--only-changed=$GITHUB_BASE_REF`.
During local development, it can be used to quickly filter down to the
touched set of tests suites.
In some rare usecases, this can also help to cut down on CI usage for
pull requests. Tread with caution though.
File dependencies are taken into account to ensure that if you touched a
utility file, all relevant tests are still executed.
Closes https://github.com/microsoft/playwright/issues/15075
Broken out of https://github.com/microsoft/playwright/pull/31727 as per
@dgozman's
[request](https://github.com/microsoft/playwright/pull/31727#discussion_r1685793229).
The PR goal is to remove the `suite` argument from the Component
testing's Vite Plugin. `suite` is used to enrich Vite's dependency graph
with information about dependencies between test suites and helper
files. It essentially merges the Vite graph with the
`compilationCache.ts > fileDependencies` graph, and then writes the
result back into `compilationCache.ts > externalDependencies`.
By refactoring this to make the connection on the reading end in
`collectAffectedTestFiles`, we can drop the `suite` parameter.
We didn't yet have a test that depended on the dependency graph being
connected correctly between `fileDependencies` and
`externalDepedencies`, so I've [extended an existing
test](53a539938b)
to capture that.
When collecting dependencies both from CJS loader and from ESM loader,
the latter would overwrite the dependencies set instead of appending.
Also make sure cts/cjs/mts/mjs are all supported equally.
