test(wtr): remove unnecessary support for .only files @W-19098252#5513
Conversation
instead of weird fake module
There's no setup/teardown needed, it's a single test, and WTR provides per-file encapsulation
working toward just importing and executing things, but not quite there yet
two env vars for the same goal is unnecessary
I think the last one was a concurrency related timeout, which was previously addressed.
helper files shouldn't have side effects; all setup should be in the setup file
no longer necessary
all tests are run in isolation
it's just one code blob now, not multiple scripts
ensures we never accidentally use the wrong one
Web Test Runner lets you specify individual files via CLI, so the workaround is not necessary.

The
.onlyfile hack was originally implemented for tests because there was no alternative way to focus on a single test.Web Test Runner allows you to specify a single file to execute (e.g .
yarn test:hydration test-hydration/some/test/index.spec.js), so this workaround is not necessary.Details
