Я хочу написать Integration Test на контроллере моего приложения Spring WebFlux, но я не хочу использовать ни @WebFluxTest, ни @SpringBootTest ...
Почему?
Это потому, что эти аннотации запускают все приложение, которое занимает много секунд, и я просто хочу протестировать контроллер.
Что я хочу сделать, так это написать тесты, которые мы могли бы сделать в классическом Spring Web Application с MockMvc.
Моя проблема в том, что я не знаю, как настроить свой View Resolver, поэтому при запуске теста я получаю эту ошибку:
16:56:35.881 [main] ERROR org.springframework.web.server.adapter.HttpWebHandlerAdapter - [22a6d75c] 500 Server Error for HTTP GET "/product"
java.lang.IllegalStateException: Could not resolve view with name '/product/product'.

Поскольку я использую Apache Freemarker, я попытался добавить
@Import({ FreeMarkerAutoConfiguration.class})
Но у меня на самом деле нет контекста Reactive, поэтому все необходимые компоненты не создаются из-за:
@ConditionalOnWebApplication(type = ConditionalOnWebApplication.Type.REACTIVE)
Итак, я попытался создать отсутствующие компоненты самостоятельно:
@Bean
public FreeMarkerViewResolver freeMarkerViewResolver(FreeMarkerProperties properties) {
FreeMarkerViewResolver resolver = new FreeMarkerViewResolver();
resolver.setPrefix(properties.getPrefix());
resolver.setSuffix(properties.getSuffix());
resolver.setRequestContextAttribute(properties.getRequestContextAttribute());
resolver.setViewNames(properties.getViewNames());
return resolver;
}
@Bean
public ViewResolverRegistry viewResolverRegistry (ApplicationContext applicationContext, FreeMarkerViewResolver freeMarkerViewResolver) {
ViewResolverRegistry viewResolverRegistry = new ViewResolverRegistry(applicationContext);
viewResolverRegistry.viewResolver(freeMarkerViewResolver);
return viewResolverRegistry;
}
@Bean
public WebFluxConfigurationSupport webFluxConfigurationSupport(ViewResolverRegistry viewResolverRegistry) {
WebFluxConfigurationSupport webFluxConfigurationSupport = new WebFluxConfigurationSupport();
ReflectionTestUtils.setField(webFluxConfigurationSupport, "viewResolverRegistry", viewResolverRegistry);
return webFluxConfigurationSupport;
}
Но это не работает ...
Ну, я не понимаю, как я могу просто написать этот тест и сделать его простым ...
Контроллер:
package fr.myclient.product.controller;
import fr.myclient.product.service.ProductService;
import lombok.AllArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestHeader;
import org.springframework.web.bind.annotation.RequestMapping;
import reactor.core.publisher.Mono;
@Slf4j
@Controller
@RequestMapping(value = "/product")
@AllArgsConstructor
public class ProductController {
private ProductService productService;
@GetMapping
public Mono<String> getProduct(Model model, @RequestHeader(name = "productId") String productId) {
return this.productService.getProduct(productId)
.doOnNext(p -> model.addAttribute("product", p))
.thenReturn("/product/product");
}
}
Интеграционный тест:
package fr.myclient.product.controller;
import fr.myclient.product.config.ControllerTestConfiguration;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Tag;
import org.junit.jupiter.api.Test;

import org.springframework.test.web.reactive.server.WebTestClient;
@Tag("IntegrationTest")
@ExtendWith(SpringExtension.class)
@ContextConfiguration(classes = ControllerTestConfiguration.class)
public class ProductControllerIntegrationTest {
@Autowired
private ProductController productController;
protected WebTestClient client;
@BeforeEach
public void setUp() throws Exception {
client = WebTestClient.bindToController(productController).build();
}
@Test
public void shouldGetProduct() throws Exception {
client.get()
.uri("/product")
.header("productId", "12345678")
.accept(MediaType.APPLICATION_JSON_UTF8)
.exchange()
.expectStatus()
.isOk();
}
}
Конфигурация ControllerTest:
package fr.myclient.product.config;
import fr.myclient.product.model.Product;
import fr.myclient.product.service.ProductService;
import org.mockito.Mockito;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;

@Configuration
@ComponentScan(basePackages = "fr.myclient.product.controller")
public class ControllerTestConfiguration {
@Bean
public ProductService productService() {
ProductService mockProductService = Mockito.mock(ProductService.class);
Product data = Product.builder()
.code("12345678")
.build();
Mono<Product> monoProduct = Mono.just(data);
when(mockProductService.getProduct("12345678")).thenReturn(monoProduct);
return mockProductService;
}
}
