Do you know how to mock $t from i18n ?

[frck006]

Hi,

I wonder If you have an example about how to mock "$t" in the template of a component ?
Example:

<TextInput
	labelText={$t(label)}
/>

I use Vitest.dev to run unit test.
I try to mock a module '$lib/translations'.
It's ok for the method "get", but I don't know how to do about "subscribe".

vi.mock('$lib/translations', async () => {
	// // Import partiel du module. 
	const mod = await vi.importActual<typeof import('$lib/translations')>('$lib/translations')
	const t = {
		...mod.t,
		subscribe: vi.fn().mockImplementation(() => ({ unsubscribe: () => vi.fn() })),
		// subscribe: () => 'XXXXXXXXXXXXXXXXXXXXXXXXXX',
		get: vi.fn().mockReturnValue('Code'),
	}
	return { ...mod, t }
})

Regards

I was wondering about the same thing, for my particular case I just used a readable with a function that returns back the key:

vi.mock('$lib/i18n', async () => {
	return { t: readable((key: string) => key) };
});
