@WebFluxTest Doesn't Import the ErrorWebFluxAutoConfiguration #16258
Description
Synopsis
As I was experimenting with the @WebFluxTests to test Reactive controllers, I noticed that the provided test auto-configurations do not import the default ErrorWebExceptionHandler, so the following test would fail:
@AutoConfigureErrors
@RunWith(SpringRunner.class)
@WebFluxTest(PersonController.class)
public class ReactiveWebApplicationTests {
@Autowired private WebTestClient webClient;
@Test
public void personName_CanNotBeBlank() {
webClient.post().uri("/persons")
.contentType(MediaType.APPLICATION_JSON_UTF8)
.syncBody("{}")
.exchange()
.expectStatus().isBadRequest()
.expectBody()
.jsonPath("$.errors[0].code").isEqualTo("name.blank");
}
}This can be easily fixed just by importing the ErrorWebFluxAutoConfiguration:
@AutoConfigureErrors
@RunWith(SpringRunner.class)
@WebFluxTest(PersonController.class)
@ImportAutoConfiguration(ErrorWebFluxAutoConfiguration.class)
public class ReactiveWebApplicationTests {
@Autowired private WebTestClient webClient;
@Test
public void personName_CanNotBeBlank() {
webClient.post().uri("/persons")
.contentType(MediaType.APPLICATION_JSON_UTF8)
.syncBody("{}")
.exchange()
.expectStatus().isBadRequest()
.expectBody()
.jsonPath("$.errors[0].code").isEqualTo("name.blank");
}
}Suggestion
Although the problem is so easy to fix, that'd be great if we import the default auto-configuration automatically. For example by adding an AutoConfigureErrorWebFlux annotation.

Apparently supporting WebExceptionHandlers was added in #13627 but the default auto-configuration is missing from the WebFluxTest.
