Is it possible to use stubFor here? If yes, how to do it? If not, how to test this code?

    public Mono<Void> trelloCallback(Type payload) {
        webClient.post()
                 .uri(URL)
                 .bodyValue(payload)
                 .headers(httpHeaders -> httpHeaders.add(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE))
                 .retrieve()
                 .bodyToMono(Void.class)
                 .subscribe();
        return Mono.empty();
    }

Info: If we add .subscribe to the code, it runs in the background.

I test the result, and I can see WireMock.stubFor is working with the subscribe call.

For more explanation, We first create a WireMock.stubFor for some endpoint call. Then we make an actual call using the webTestClient to do integration test. And then verify the result using

verify(exactly(1), postRequestedFor(urlEqualTo(SOME_URL)));
// For SOME_URL create a `stubFor`
