在编写控制器的单元测试时模拟自定义验证器的依赖项

编程问答 2022-06-15

问题描述

我正在为Spring Boot应用程序的controller编写单元测试。
我使用了Custom Validator来验证请求正文数据，验证器依赖于另一个组件ConstantManager，它是一个弹簧@Component。

当我运行测试时，得到一个exception。

自定义验证器 

public class MessageValidator implements ConstraintValidator<ValidateTMessage,List<Message>> {

private ConstantManager constantManager;

@Autowired
public MessageValidator(ConstantManager constantManager) {
    this.constantManager = constantManager;
}

@Value("${message.length.max}")
@Setter
private int messageLength;


@Override
public boolean isValid(List<Message> message,ConstraintValidatorContext context) {
       // logic
    return true;
}

}

ControllerTest 

@Test
void whenCreateServiceWithValidDataThenReturn_201() throws Exception {
    String appId = "AppId";
    ServiceDetails service = initServiceDetailsObj();
    given(anbservicesService.createServiceConfig(appId,service)).willReturn(service);
    given(constantManager.isLanguageAllowed(any())).willReturn(true);
    given(constantManager.isValid(any())).willReturn(true);

    mockMvc
            .perform(MockMvcRequestBuilders.post(BASE_URL+"/config")
                    .header("appId",appId)
                    .contentType(MediaType.APPLICATION_JSON)
                    .content(objectMapper.writeValueAsString(service)))
            .andDo(print())
            .andExpect(status().isCreated())
            .andExpect(MockMvcResultMatchers.jsonPath("$.id",is(service.getId())))
            .andExpect(MockMvcResultMatchers.jsonPath("$.name",is(service.getName())))
            .andExpect(MockMvcResultMatchers.jsonPath("$.config").isNotEmpty());
}

ConstantManager 

@Component
public class ConstantManager {
private static final Map<String,Map<Data,String[]>> voices = new TreeMap<>();

private static List<String> countries = new ArrayList<>();


private CountryRepository countryRepository;

@Autowired
public ConstantManager(CountryRepository countryRepository) {
    this.countryRepository = countryRepository;
}


public boolean isLanguageAllowed(String language) {
    return voices.containsKey(language.toLowerCase());
}

public boolean isCountryCodeExist(String countryCode) {
    return countries.contains(countryCode.toLowerCase());
}

void loadCountries() {
    // code 
}

void constructVoices() {
   // code
}

private String[] getVoices(String language,Data data) {
    code
}

public boolean isValidVoice(int position,String language,Data data) {
   //code
}
