Question

如何测试接收ServerRequest并返回Mono<ServerResponse>的 handler 方法？

我可以通过ServerRequest创建一个org.springframework.mock.web.reactive.function.server.MockServerRequest.builder()。然后在ServerResponse.statusCode()上声明。但是，我想测试此ServerResponse的正文，但无法提取它。

ServerResponse response = target.search(MockServerRequest.builder()
    .method(HttpMethod.GET)
    .build()
  ).block();

assertThat(response.statusCode()).isEqualTo(HttpStatus.OK);
//assertThat(response.body()).isNotNull();

我不想使用WebTestClient进行更广泛的测试，我想使用单元测试来测试所有可能的响应情况。

谢谢

Answer 1

因此，看来最好的解决方案是使用WebTestClient。但是，可以在没有运行服务器的情况下使用此服务器。

spring-test模块包括一个WebTestClient，可用于在有或没有运行服务器的情况下测试WebFlux服务器端点。

技巧是使用bindTo..()构建器方法。就我而言，bindToRouterFunction(new MyRouter(new MyHandler()))效果很好

我有完全相同的问题，因为我不想为每个测试都启动整个Spring上下文。感谢您自己回答中的信息，这对我有所帮助。这是一个完整的示例，包括Mockito和JUnit5：

import java.util.Arrays;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.junit.jupiter.MockitoExtension;
import org.springframework.http.MediaType;
import org.springframework.test.web.reactive.server.WebTestClient;

@ExtendWith(MockitoExtension.class)
class UsersHandlerTest {
  @Mock
  UserRepository userRepository;

  WebTestClient client;

  @BeforeEach
  public void setUp() {
    UsersHandler usersHandler = new UsersHandler(userRepository);
    Router router = new Router(usersHandler);

    Mockito.when(userRepository.findAll()).thenReturn(
      Arrays.asList("", ""));

    client = WebTestClient.bindToRouterFunction(router.getUsers()).build();
  }

  @Test
  public void getCommands() {
    client.get().uri("/users")
      .accept(MediaType.APPLICATION_JSON_UTF8)
      .exchange()
      .expectStatus().isOk()
      .expectBody().json("{}");
  }
}

我已经要求 similar question 坚持不使用 WebTestClient。在发现可以将响应转换为允许检查主体（实体）的类型后，我最终回答了我自己的问题。

魔术线（Kotlin）是：

df <- structure(list(source = c("o", "o", "n", "n", "o", "o", "n", 
"n", "o", "o", "n", "n", "o", "o", "n", "n", "o", "o", "n", "n", 
"o", "o", "n", "n"), activty = c("low", "high", "low", "high", 
"low", "high", "low", "high", "low", "high", "low", "high", "low", 
"high", "low", "high", "low", "high", "low", "high", "low", "high", 
"low", "high"), jar = c("blank1", "blank1", "blank1", "blank1", 
"jar1", "jar1", "jar1", "jar1", "jar2", "jar2", "jar2", "jar2", 
"blank2", "blank2", "blank2", "blank2", "jar3", "jar3", "jar3", 
"jar3", "jar4", "jar4", "jar4", "jar4"), sampling = c("blank",

"soil", "soil", "soil", "blank", "blank", "blank", "blank", "soil", 
"soil", "soil", "soil", "soil", "soil", "soil", "soil"), x = c(34L, 
31L, 32L, 35L, 21L, 22L, 23L, 23L, 27L, 28L, 29L, 27L, 34L, 32L, 
31L, 36L, 25L, 25L, 26L, 25L, 19L, 18L, 20L, 20L), y = c(46L,

45L, 48L, 37L, 37L, 38L, 37L, 34L, 30L, 34L, 33L), x_pct = c(1, 
1.02, 0.98, 1.01, 1.62, 1.43, 1.37, 1.54, 1.26, 1.13, 1.09, 1.31,

1.78), y_pct = c(0.99, 1.01, 1.01, 1.01, 1.38, 1.28, 1.31, 1.36, 
1.17, 0.95, 1.09, 1.22, 1.01, 0.99, 0.99, 0.99, 1.23, 1.18, 1.17, 
1.28, 1.34, 1.45, 1.31, 1.44)), class = "data.frame", row.names = c(NA, 
-24L))

Spring Webflux，测试`ServerResponse`
