What was happening?
- When we use CT, we go over the test files, look at the imports using
`tsxTransform.ts` and store them inside a map, these we feed into the
import registry which we build using Vite and have access inside the
browser
- In case of an inline component in the same file as where the test file
is, this is not happening.
- jsx-runtime via babel kicks in, transforms every JSX component in
something like that:
```
{
__pw_type: 'jsx',
type: [Function: MyInlineComponent],
props: { value: 'Max' },
key: undefined
}
```
this then gets passed into `wrapObject` which maps any function from the
Node.js side into expose function calls so they work inside the browser.
The assumption for `wrapObject` was to do it mostly for callbacks. So it
does for `type` - which is actually our component. We then pass this to
the React render function, which calls back the exposed function but we
never return anything, so it mounts `undefined`.

While there have been experiments from certain vendors to get the
'client only' code inside a server side file, we should throw for now to
not confuse users. We might revisit this in the future since Babel / TSX
doesn't support it outside of the box.
Fixes https://github.com/microsoft/playwright/issues/32167
Instead of plumbing it through a custom unspecified config field, make
it a part of plugin interface.
Additionally, use task runner for starting/stopping dev server.
Supercedes https://github.com/microsoft/playwright/pull/31915, closes

When TypeScript resolves a specifier via path mapping, it does not
interpret `package.json`. If path mapping resolves to a directory, it
only looks at the `index.js` file in that directory if it's in CommonJS
mode.
We need to mirror this in our `esmLoader.ts`.

Currently, when the server notifies the UI about changed files, the UI
determines what files to re-run based on an old test list. By listing
tests before that, we make sure that the test list is up-to-date, and
that added tests are included in the next run.
I've also removed the `listChanged` event as discussed in the team sync.
The event isn't used anywhere and fires in exactly the same cases where
`testFilesChanged` fired, so i've folded them into one another. This allowed simplifying `Watcher`.
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.
