The setup file runs once per test file and imported all eight message catalogs, several hundred kilobytes each, which made setup the largest share of a component-suite run. It now primes EN, the fallback floor of the t() chain. A test that renders another locale primes it at module scope through primeLocales(), which loads the catalog via the production loader in a file-level beforeAll.

/**
|
|
* Unit-test setup.
|
|
*
|
|
* Seed the client-side locale cache with the EN bundle. In production
|
|
* only the active locale reaches the client (boot script, then dynamic
|
|
* import on switch — see `src/lib/i18n/load-locale.ts`). Tests mount
|
|
* `I18nProvider` standalone — often with `renderToStaticMarkup`, which
|
|
* is synchronous and cannot await a dynamic import — so EN, the fallback
|
|
* floor of the t() chain, is primed up front.
|
|
*
|
|
* Only EN. Every catalog is several hundred kilobytes and this file runs
|
|
* once per test file, so priming all of them made setup the largest share
|
|
* of a unit run. A test that renders another locale primes it itself:
|
|
*
|
|
* import deMessages from "../../../messages/de.json";
|
|
* primeMessages("de", deMessages);
|
|
*
|
|
* Server-side translation (`getServerTranslator`, `shared-resolve`) holds
|
|
* every catalog on its own and needs no priming.

* Several paths start a promise, return without awaiting it, and log on the

|

|
|
* console write to the main thread as an `onUserConsoleLog` RPC call and
|
|
* rejects whatever is still pending on that channel while it tears a test file
|
|
* down, so a write that lands in that window fails the whole run with

|
|
* — blamed on the file the worker was tearing down, which is not the test that
|
|
* started the work and need not log anything of its own. Awaiting the
|
|
* registered tasks here removes the precondition instead of muting the
|
|
* console, which would have thrown away a real signal and left the
|
|
* non-determinism in place. See `src/lib/logging/background-tasks.ts`.
