This is a breaking change, but it simplifies mental model A LOT. Scoped fixtures can only use other scoped fixtures with a higher scope, and scope is explicit (but overriding the fixture also inherits all the options by default, like in PW).
By default, any extended value has a test scope. You cannot override the extended value to provide a DIFFERENT scope, it now throws an error. This is needed to remove the ambiguity of defining a worker fixture and then overriding its "static" dependency inside the suite:
// this worked previously
const test = base
.extend('port', 5300)
.extend('config', { scope: 'worker' }, ({ port }) => {
return `localhost:${port}`
})But if you want to override the port, you need to invalidate or overwrite the WORKER fixture that we already initialized - which makes little sense
test.override('port', 5000) // what to do here?Using test.override with a scope other than test in general is now forbidden, unless it's called at the top level of the file (which still causes some unexpected issues with worker fixtures because they will leak to other test files in the same worker - I wonder if we could force a new worker instead).

This also makes it so you cannot call test.extend('', { scope: 'file' }) inside a suite, it's only allowed in the top level of the module now

I wasn't checking these test cases previously and the new extend/override behavior makes sense to me.

Damn it, snapshots fail on rolldown because it processes files differently 😡 |
