What:
Makes our dependency on
@testing-library/dom
optional.Why:
@testing-library/dom
is a sizable dependency to pull in just for the name of the queries which are a pretty static thing, and it is possible to usejest-dom
without@testing-library
; it also conflicts with Yarn PnP when using a more specific variant as it's recommended to not have@testing-library/dom
as a dependency in that case.How:
Using the same logic to what we do in
eslint-plugin-jest
for extending@typescript-eslint/eslint-plugin
rules - in this case, we have a default list of queries we expect to exist which we use if we're not able to get a more up-to-date list via requiring@testing-library/dom
.Note that I have purposely not added support for checking for more specific variants as part of this change; I plan to do that as a follow-up once this has been landed.
