Небольшой вопрос по модульному тестированию с веб-клиентом Junit5 + Spring.
У меня есть базовый класс @Service с веб-клиентом @Autowired.

Код: Выделить всё

@Autowired private final WebClient webClient;
private MyAtServiceClass(WebClient webClient) {
this.webClient = webClient;
}

public Mono sendHttpRequestToSomewhere(String payload) {
return webClient.mutate().baseUrl("http://...").build().post().body(BodyInserters.fromValue(payload)).retrieve().bodyToMono(MyPojo.class);
}

Поскольку я просто хочу провести модульное тестирование, я делаю «макет» со следующим в своем тестовом классе:

Код: Выделить всё

String payload = getSomeHardedCodedJsonPayload();
WebClient webClient = WebClient.builder()
.exchangeFunction(clientRequest ->
Mono.just(ClientResponse.create(HttpStatus.OK)
.header("content-type", "application/json")
.body(payload)
.build())
).build();

MyAtServiceClass myAtServiceClass     = new MyAtServiceClass(webClient);
Mono mono = myAtServiceClass.sendHttpRequestToSomewhere();
assertEquals(“foo”, mono.block().getFoo());

Однако, когда я запускаю модульный тест, ожидая, что он просто вернет мне мой манекен, я получаю сообщение об исключении отказа в соединении ниже.
Какова основная причина, пожалуйста?

Код: Выделить всё

Небольшой вопрос по модульному тестированию с веб-клиентом Junit5 + Spring.
У меня есть базовый класс @Service с веб-клиентом @Autowired.
[code]@Autowired private final WebClient webClient;
private MyAtServiceClass(WebClient webClient) {
this.webClient = webClient;
}

public Mono sendHttpRequestToSomewhere(String payload) {
return webClient.mutate().baseUrl("http://...").build().post().body(BodyInserters.fromValue(payload)).retrieve().bodyToMono(MyPojo.class);
}
[/code]
Поскольку я просто хочу провести модульное тестирование, я делаю «макет» со следующим в своем тестовом классе:
[code]String payload = getSomeHardedCodedJsonPayload();
WebClient webClient = WebClient.builder()
.exchangeFunction(clientRequest ->

).build();

MyAtServiceClass myAtServiceClass     = new MyAtServiceClass(webClient);
Mono mono = myAtServiceClass.sendHttpRequestToSomewhere();
assertEquals(“foo”, mono.block().getFoo());
[/code]
Однако, когда я запускаю модульный тест, ожидая, что он просто вернет мне мой манекен, я получаю сообщение об исключении отказа в соединении ниже.
Какова основная причина, пожалуйста?
