testing an async store

[till]

Hey,

I am trying to test a store in isolation — without any components.

In the past, I used the following to mock fetch calls in svelte and wanted to do something similar for the store:

		beforeEach(() => {
			fetchMocker.mockIf(/^http:\/\/api-testing\.local.*$/, (req) => {
				let body
				let status = 200
				if (req.url.endsWith('/path')) {
					body = pathJsonResponse
				}

				return {
					status: status,
					headers: {
						'Content-Type': 'application/json',
					},
					body: JSON.stringify(body),
				}
			})
		})

When I use this method with my test, the store never finishing loading. I suspect this is due to the async nature of my calls, which works well in the app. But how do I tell vitest to wait for it to load in a test case?
