springboot~WebTestClient的使用

在使用springboot进行开发时，单元测试是必要的，当你建立一个spring项目时，它会为我们自己生成一个测试项目，当你的项目开始过程中，测试用例是同时要进行的，我们在进行WEB层的集成测试时，可以使用spring为我们提供的WebTestClient工具，非常方便，提供了基于restful的各种类型和状态！

下面测试用例也是spring在github上开源的，大叔作为总结，把它收录在博客里。

package com.example.webclientdemo;

import com.example.webclientdemo.payload.GithubRepo;
import com.example.webclientdemo.payload.RepoRequest;
import org.assertj.core.api.Assertions;
import org.junit.FixMethodOrder;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.MethodSorters;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.reactive.server.WebTestClient;
import reactor.core.publisher.Mono;


@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class WebclientDemoApplicationTests {

    @Autowired
    private WebTestClient webTestClient;

    @Test
    public void test1CreateGithubRepository() {
        RepoRequest repoRequest = new RepoRequest("test-webclient-repository", "Repository created for testing WebClient");

        webTestClient.post().uri("/api/repos")
                .contentType(MediaType.APPLICATION_JSON_UTF8)
                .accept(MediaType.APPLICATION_JSON_UTF8)
                .body(Mono.just(repoRequest), RepoRequest.class)
                .exchange()
                .expectStatus().isOk()
                .expectHeader().contentType(MediaType.APPLICATION_JSON_UTF8)
                .expectBody()
                .jsonPath("$.name").isNotEmpty()
                .jsonPath("$.name").isEqualTo("test-webclient-repository");
    }

    @Test
    public void test2GetAllGithubRepositories() {
        webTestClient.get().uri("/api/repos")
                .accept(MediaType.APPLICATION_JSON_UTF8)
                .exchange()
                .expectStatus().isOk()
                .expectHeader().contentType(MediaType.APPLICATION_JSON_UTF8)
                .expectBodyList(GithubRepo.class);
    }

    @Test
    public void test3GetSingleGithubRepository() {
        webTestClient.get()
                .uri("/api/repos/{repo}", "test-webclient-repository")
                .exchange()
                .expectStatus().isOk()
                .expectBody()
                .consumeWith(response ->
                        Assertions.assertThat(response.getResponseBody()).isNotNull());
    }

    @Test
    public void test4EditGithubRepository() {
        RepoRequest newRepoDetails = new RepoRequest("updated-webclient-repository", "Updated name and description");
        webTestClient.patch()
                .uri("/api/repos/{repo}", "test-webclient-repository")
                .contentType(MediaType.APPLICATION_JSON_UTF8)
                .accept(MediaType.APPLICATION_JSON_UTF8)
                .body(Mono.just(newRepoDetails), RepoRequest.class)
                .exchange()
                .expectStatus().isOk()
                .expectHeader().contentType(MediaType.APPLICATION_JSON_UTF8)
                .expectBody()
                .jsonPath("$.name").isEqualTo("updated-webclient-repository");
    }

    @Test
    public void test5DeleteGithubRepository() {
        webTestClient.delete()
                .uri("/api/repos/{repo}", "updated-webclient-repository")
                .exchange()
                .expectStatus().isOk();
    }
}

本例主要用来测试响应式的mongodb控件，其中也有一些坑，我们在reactive-mongodb一节里再说！
