Reactive repository does not save an object - mongodb

Question

I think I don't understand well how a Reactive repository and handlers using it work. I have written a special test class only to test the simpliest handler using a repository
#SpringBootTest
class TestRepository() {
#Autowired
lateinit var myRepo: myRepo
#Autowired
lateinit var myHandler: MyHandler
#Test
fun `save with a handler`() {
val myObject = MyObject()
myHandler.save(request).subscribe()
StepVerifier.create (myRepository.count() ) <--this does not work
.expectNext (1L )
.expectComplete().verify()
}
#Test
fun `test only database saving`() {
val object = MyObject()
myRepo.save(myRepo).subscribe()
StepVerifier.create (myRepo.count() ) <-- this works
.expectNext (1L )
.expectComplete().verify()
}
}
my handler and repository are defined in the following way:
#Service
class MyHandler(private val myRepository: MyRepository) {
fun save(object: MyObject): Mono<MyObject> {
return myRepository.save(request)
}
}
#Repository
interface MyRepo : ReactiveMongoRepository<MyObject, String> {
fun save(request: MyObject): Mono<MyObject>
}
I also tried to play with subscribe method but it still does not see the results.
What should I correct?

Use Mono.then function to chain save and count functions and get a resulting Mono:
#Test
fun `save with a handler`() {
val countAfterSave = myHandler.save(MyObject()).then(myRepository.count());
StepVerifier.create(countAfterSave)
.expectNext(1L)
.expectComplete()
.verify()
}
