org.mockito.exceptions.verification.TooManyActualInvocations:
Wanted 1 time:

Using the appropriate VerificationMode:
import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;
verify(mockObject, atLeast(2)).someMethod("was called at least twice");
verify(mockObject, times(3)).someMethod("was called exactly three times");

For Kotlin:
build gradle:
testImplementation "com.nhaarman.mockitokotlin2:mockito-kotlin:2.2.0"
code:
interface MyCallback {
fun someMethod(value: String)
}
class MyTestableManager(private val callback: MyCallback){
fun perform(){
callback.someMethod("first")
callback.someMethod("second")
callback.someMethod("third")
}
}
test:
import com.nhaarman.mockitokotlin2.times
import com.nhaarman.mockitokotlin2.verify
import com.nhaarman.mockitokotlin2.mock
...
val callback: MyCallback = mock()
val uut = MyTestableManager(callback)
uut.perform()
val captor: KArgumentCaptor<String> = com.nhaarman.mockitokotlin2.argumentCaptor<String>()
verify(callback, times(3)).someMethod(captor.capture())
assertTrue(captor.allValues[0] == "first")
assertTrue(captor.allValues[1] == "second")
assertTrue(captor.allValues[2] == "third")
