Can't we just wrap exports here:
?

And while we are here, let's throw an error, if factory returns non-object. (With a help message that it should return { default }, if user wants to mock default export)

I split the proxy objects. The export object proxy is now happening where you suggested, and the factory proxy object is now returning an error if the return value is not an object.

Why do we need a proxy, if we can just check it here:
https://github.com/jereklas/vitest/blob/bdd74e50836a70d9aae410781f5c6fdbe5093f3a/packages/vitest/src/runtime/mocker.ts#L109
?
Factory can also return a promise that resolves to primitive

You need the proxy on the exports object because you don't know which export is being accessed until the calling code imports something?
I need to head to bed, but will try taking a look at your factory related concern tomorrow.

We do need a roxy for exports object, but I don't see why we need proxy for calling a factory - we are calling it ourselves on https://github.com/jereklas/vitest/blob/bdd74e50836a70d9aae410781f5c6fdbe5093f3a/packages/vitest/src/runtime/mocker.ts#L109

Ah gotcha. I misunderstood your statement.

Should also check null, i think?

Looks like a test unrelated to my changes failed in CI? I ran them locally without any issue. What's the process for getting tests re-ran? |
