if I have an interface like

interface LocalsearchCustomerClient {
	fun <http://Customer.post|Customer.post>(): Flux<URI>
}

and a test using Mockito like @Mock private lateinit var localsearchCustomerClient: LocalsearchCustomerClient, can I mock the call somehow?

I tried `Mockito.`when`(localsearchCustomerClient.run(any<LocalsearchCustomerClient.() -> Flux<URI>>())).thenReturn(Flux.empty())` but that gives me Misplaced or misused argument matcher detected here.

or, oth, am I trying too hard to use extension functions here? should it just be fun post(customer: Customer): Flux<URI>?

Please use #mockk instead. Mockito even with mockito-kotlin is a poor mocking framework with outdated architecture and inconsitent API. Use a real mocking framework designed for Kotlin from the ground up.

Thanks, did not know about mockk!
