How to reset singleton instance in tests.

[Podul]

Hi!
I added the container trait and tried to call Container.shared.reset(), Scope.singleton.reset() and Container.shared.db.reset(), it doesn't work.
Here‘s a simple example:

extension Container {
    var db: Factory<MyType> {
        self { MyType() }
        .singleton
    }
}

@Suite(.container { $0.mock() })
struct xxxTests {}

extension Container {
    func mock() {
        self.reset()
        // self.db.reset()
        // Scope.singleton.reset()
    }
}

Thanks a lot for your help. 🙏

Container.shared.reset only resets container registrations, options, and caches. Has no effect on resolved singletons.

Resetting db should clear db's registrations, options, and clear its entry in the singleton cache.

Scope.singleton.reset() should zap a previously resolved singleton.

I reran the tests on those, should work. If not, need a minimum project that illustrates error.

The reason is that I imported FactoryKit into both the main target and the test target.
Once I removed it from the test target, it worked.

Thank you for your time.

Yep, that's bad. Added a specific warning against that to the README

Do not, however, import FactoryKit into the Test target. That can lead to duplicate factories and indeterminate behavior.
