如何使用@WebfluxTest 测试异常 [英] How to test exception with @WebfluxTest
问题描述
我正在尝试使用 @WebfluxTest
测试我的控制器的异常路径,但它总是抛出服务器异常,然后返回 500 错误.
I am trying to test exception path for my controller with @WebfluxTest
, but it is always throws a server exception and then return a 500 error.
测试代码是这里:
@Test
@Ignore // ignore it temporarily
public void getPostByNonExistedId_shouldReturn404() {
given(posts.findById("1"))
.willReturn(Mono.empty());
client.get().uri("/posts/1").exchange()
.expectStatus().isNotFound();
verify(this.posts, times(1)).findById(anyString());
verifyNoMoreInteractions(this.posts);
}
控制器代码为:
@GetMapping("/{id}")
public Mono<Post> get(@PathVariable("id") String id) {
return this.posts.findById(id).switchIfEmpty(Mono.error(new PostNotFoundException(id)));
}
PostNotFoundException
在后台被正确捕获,但在我的 @WebfluxTest
测试中没有被我的自定义 RestExceptionHandler
处理.
The PostNotFoundException
is caught in the background correctly, but it is not handled by my custom RestExceptionHandler
in my @WebfluxTest
test.
推荐答案
对于这个问题的未来听众,这个问题被提出为 一个针对 Spring Boot 问题跟踪器的问题 由问题作者提出,并已通过添加对 WebExceptionHandler
的支持解决在 @WebFluxTest
中,所以有问题的代码应该可以正常工作,因为 在撰写本文时尚未发布的 Spring Boot 2.1.0.M3.
For the future audience for this question, this question was raised as an issue against the Spring Boot issue tracker by the author of the question and has been resolved via adding support for WebExceptionHandler
in @WebFluxTest
, so the code in question should just work since the Spring Boot 2.1.0.M3 which is not released yet at the time of writing.
