[FIXED] Error while injecting MockMvc with Spring Boot

Issue

I'm trying to use mockmvc but it always shows the error:

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.test.web.servlet.MockMvc' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

My class:

@AutoConfigureMockMvc
@ExtendWith(SpringExtension.class)
@TestPropertySource(locations = "classpath:application-cliente.properties")
public class ClienteRepositoryTest {

    @Autowired
    private MockMvc mockMvc;

    @MockBean
    private ClienteService clienteService;

    @Test
    public void simpleMockTest() throws Exception {
        var clienteMock = new Cliente("Jessica Pereira");
        Mockito.doReturn(Optional.of(clienteMock)).when(clienteService).buscar(2L);
        this.mockMvc.perform(MockMvcRequestBuilders.get("/api/clientes/pf/{id}", 1L))
                .andExpect(MockMvcResultMatchers.status().isOk());
    }
}

And my gradle

plugins {
    id 'org.springframework.boot' version '2.1.3.RELEASE'
    id 'java'
}

apply plugin: 'io.spring.dependency-management'

group = 'com.rjdesenvolvimento'
version = '0.0.1'
sourceCompatibility = '11'

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
    maven { url 'https://repo.spring.io/milestone' }
}

ext {
    set('springCloudVersion', 'Greenwich.SR1')
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.cloud:spring-cloud-starter-oauth2'
    implementation 'org.springframework.cloud:spring-cloud-starter-security'
    compileOnly 'org.projectlombok:lombok'
    compile('org.glassfish.jaxb:jaxb-runtime:2.3.1')
    runtimeOnly 'org.springframework.boot:spring-boot-devtools'
    runtimeOnly 'org.postgresql:postgresql'
    annotationProcessor 'org.projectlombok:lombok'
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'junit', module: 'junit'
    } '
    testRuntime 'org.junit.jupiter:junit-jupiter-api'
    testRuntime 'org.junit.jupiter:junit-jupiter-engine'
    testRuntime 'com.h2database:h2'
}

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

test {
    useJUnitPlatform()
}

Solution

@AutoConfigureMockMvc should be used with @SpringBootTest or instead you can use @WebMvcTest to just load Spring MVC infrastructure for limited controller(s).

Often, @WebMvcTest is limited to a single controller and is used in combination with @MockBean to provide mock implementations for required collaborators.

@WebMvcTest also auto-configures MockMvc. Mock MVC offers a powerful way to quickly test MVC controllers without needing to start a full HTTP server.

You can also auto-configure MockMvc in a non-@WebMvcTest (such as @SpringBootTest) by annotating it with @AutoConfigureMockMvc.
