Module.verify() (koin 4.0.0) doesn’t report missing dependency when binding to an interface.
Even though in the following setup dataStore is not declared, the test passes.

single<AuthRepository> {
    AuthRepositoryImpl(
       dataStore = get()
    )
}

In the test logs there is only this mention about AuthRepository :

|-> definition [Singleton: 'com.example.koinscope.model.repositories.AuthRepository']
| bind types: [class com.example.koinscope.model.repositories.AuthRepository]

Does verify require additional setup to properly check the dependencies of the concrete implementations?

Migrate to Koin constructor dsl, in your module. And run the test again, please.

single(::AuthRepositoryImpl)

[Mihai Batista]

@Pedro Francisco de Sousa Neto it worked, thanks for the pointer!

[Mihai Batista]

when retrieving a named definition the documentation hints at using the standard dsl, is there a way to make use of verify for that case?

[Pedro Francisco de Sousa Neto]

Unhappily verify function just check your parameters if you're using Koin Constructor DSL. There is a lack of implementation, I guess. 😢

To check dependencies without migrating to constructor dsl you need to use the checkDependencies. But is deprecated.

@arnaud.giuliani one more person suffering with this scenario again. FYI

[arnaud.giuliani]

you would need to discouple the inner definition, from the bound type: single {AuthRepositoryImpl(get()) } bind AuthRepository::class

[arnaud.giuliani]

else verify can't find what's really under the hood for yoru definition

[Mihai Batista]

@arnaud.giuliani thanks! after making this change it checks the dataStore dependency. I’ve noticed that it doesn’t check if there is a declaration with that qualifier, only that there is a definition for that type, is this something currently missing?

For ex:

single {
        AuthRepositoryImpl(
            dataStore = get(named("myStore2"))
        )
    } bind AuthRepository::class

would pass, even if there is only a dataStore named myStore1 declared.

[arnaud.giuliani]

yeah, the "named" param is not a static info ... in Koin Annotations you would be able to do so
