我正在使用webflux和springboottest在spring boot中进行测试。

 buildscript {
    ext {
        springBootVersion = '2.0.5.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}


ext {
    springCloudVersion = 'Finchley.SR1'
}

dependencies {
    compile('org.junit.jupiter:junit-jupiter-api')
    compile('org.springframework.boot:spring-boot-starter-webflux')
   testCompile('org.springframework.boot:spring-boot-starter-test')
    testRuntimeOnly("org.junit.jupiter:junit-jupiter-engine")
    testCompile('io.projectreactor:reactor-test')

}

dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
    }
}

测试用例 

@SpringBootTest
@ExtendWith({SpringExtension.class})

class DemoTest {

    private WebTestClient webTestClient;

    @BeforeEach
    void beforeEach(ReactiveWebApplicationContext context) {
        webTestClient = WebTestClient.bindToApplicationContext(context)
                .configureClient()
                .build();
    }
@Test
    void contextLoads() {
}

我遇到以下错误

org.junit.jupiter.api.extension.ParameterResolutionException: Failed to resolve parameter [org.springframework.boot.web.reactive.context.ReactiveWebApplicationContext arg0] in executable [void demo.test.DemoTest.beforeEach(org.springframework.boot.web.reactive.context.ReactiveWebApplicationContext)]

问题似乎与Spring boot和Finchley之间的版本冲突有关，因此请尝试将版本降级为2.0.1或2.0.4。

将springBootVersion = '2.0.5.RELEASE'移至springBootVersion = '2.0.1.RELEASE'或springBootVersion = '2.0.4.RELEASE'。

正如http://projects.spring.io/spring-cloud和2.0.1一起建议Finchley.SR1。

As explained in the reference documentation，您只需将@AutoConfigureWebTestClient添加到测试类中，并要求Spring Boot在测试类中注入一个已经配置的WebTestClient实例。

类似的东西：

@SpringBootTest
@ExtendWith({SpringExtension.class})
@AutoConfigureWebTestClient
class DemoTest {

    @Autowired
    private WebTestClient webTestClient;

    @Test
    void contextLoads() {
    }
}

答案 2 :(得分：0)

这是我的工薪阶层

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@AutoConfigureWebTestClient
internal class ApplicationTest {

    @Test
    fun contextLoads() {
        Assertions.assertTrue(true)
    }

}
