No qualifying bean of type 'org.springframework.test.web.servlet.MockMvc - spring-boot

Question

Spring boot 2
build.gradle:
dependencies {
implementation 'com.google.code.gson:gson:2.7'
implementation 'com.h2database:h2'
implementation 'javax.servlet:jstl:1.2'
implementation 'org.springframework.boot:spring-boot-devtools'
implementation 'org.springframework.boot:spring-boot-starter'
implementation 'org.springframework.boot:spring-boot-starter-actuator'
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
implementation 'org.springframework.boot:spring-boot-starter-jdbc'
implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'org.apache.tomcat.embed:tomcat-embed-jasper'
testImplementation('org.springframework.boot:spring-boot-starter-test') {
exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
}
testImplementation 'org.junit.jupiter:junit-jupiter:5.5.2'
}
test {
useJUnitPlatform()
}
User model:
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.validation.constraints.NotNull;
#Entity
public class User {
#Id
#GeneratedValue
private long id;
#NotNull
private String name;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
#Override
public String toString() {
return "\nUser{" +
"id = " + id +
", name = '" + name + '\'' +
'}';
}
}
in my controller:
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.ArrayList;
import java.util.List;
#RestController
public class UserController {
private UserRepository userRepository;
// If class has only one constructore then #Autowired wiil execute automatically
public UserController(UserRepository userRepository) {
this.userRepository = userRepository;
User user = new User();
user.setName("Peter");
userRepository.save(user);
}
#GetMapping("/users")
public List<User> getAllUsers() {
List<User> usersList = new ArrayList<>();
userRepository.findAll().forEach(usersList::add);
return usersList;
}
}
My repo:
import org.springframework.data.repository.CrudRepository;
public interface UserRepository extends CrudRepository<User, Integer> {
}
and here my test:
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.http.MediaType;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import java.util.ArrayList;
import java.util.List;
import static org.mockito.BDDMockito.given;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
#SpringBootTest
public class UserControllerTest {
#Autowired
private MockMvc mockMvc;
#MockBean
private UserRepository userVehicleService;
#Test
public void testExample() throws Exception {
List<User> userList = new ArrayList<>();
User user = new User();
user.setName("Peter");
userList.add(user);
given(this.userVehicleService.findAll()).willReturn(userList);
this.mockMvc.perform(MockMvcRequestBuilders.get("/users").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().string("[{\"id\":\"1\",\"name\":\"Peter\"}]"));
}
}

Add #AutoConfigureMockMvc to your test class.
