Difference in __mocks__ automocks with Jest

[EvHaus]

In Jest, when you have automocks like this:

• __mocks__
  • ora
    • index.js

This mock gets auto loaded for all tests. However, in Vitest it only gets automocked if you also add vi.mock('ora') in your tests.

Curious, is this by design? In some ways I like it because it's more explicit, but it does make migrating from Jest to Vitest more difficult.

This was done by design. We don't support automockig at this stage of development. Two main reasons are: it's more explicit and it gives better performance, since we don't need to resolve every request and try to find a mock.

I personally don't think we should support automocking. I asked people in Discord, when implemented vi.mock, and the people voted to not includid right now. If you think it's needed, you can start a discussion in Discord 👍🏻

I'm happy with this design. I would recommend updating the docs though. Perhaps add:

Unlike Jest, files in __mocks__ are not loaded unless vi.mock() is called.

in the "Automocking algorithm" section?
