Pinging @elastic/kibana-core (Team:Core)

The Core code contains just 4 leftovers

3:

• src/core/server/saved_objects/service/lib/scoped_client_provider.test.js
• src/core/server/saved_objects/service/saved_objects_client.test.js
• src/core/server/saved_objects/service/lib/repository.test.js

The last one is src/core/jest.config.js

Gonna wait until #117056 is merged for repository.test.js, as this PR impacts the file

#117259 is going to remove the last javascript files from /src/core.

I checked our owned plugins and packages, and the only ones still having javascript files are:

• /src/plugins/home/ 30 files

• /src/plugins/kibana_overview/ (TIL we own this thing) 3 files

  • such as src/plugins/kibana_overview/public/components/synopsis/synopsis.js

• packages/kbn-i18n, 1 file

  • packages/kbn-i18n/src/core/locales.js

Note that most FTR tests are not code-owner assigned, so we probably have some javascript files in /test and /x-pack/test too, such as test/api_integration/apis/status/status.js

ok, I hope we can do it #116415. Also, in the future, all the functional tests will be under appropriate domain folders.

We're no longer owners of the home plugin, and all other files have been converted to typescript. This can be closed.
