我有一个包含一些JUnit测试的项目，当我尝试使用mvn clean install package -X -e运行该项目时，我得到一个错误提示，说测试存在一些问题，这是出现的错误：

但是，如果我将项目作为JUnit测试运行，则所有测试运行良好，并且没有错误。当我阅读surfire-reports日志时，测试似乎失败了：

但是，如果我运行该特定测试，则它可以按预期运行，这就是JUnit测试。

public class SrvCreateFinancialStatementRiskAnalysisTest {

    @Mock
    ISrvIntRiskBusinessAdmissions srvIntRiskBusinessAdmissions = new SrvIntRiskBusinessAdmissions();

    @InjectMocks
    ISrvRiskBusinessAdmissionsV0 srvRiskBusinessAdmissionsV0 = new SrvRiskBusinessAdmissionsV0();

    @Mock
    BusinessServicesToolkitManager businessToolKit;

    public FinancialStatementEvaluation evaluation;

    @Before
    public void setUp() {
        MockitoAnnotations.initMocks(this);
        evaluation = FactoryCreateFinancialStatementRiskAnalysis.factoryFinancialStatementEvaluation();
    }

    @Test(expected = BusinessServiceException.class)
    public void testObligatoryParameterIdNull() {
        evaluation.setId(null);
        srvRiskBusinessAdmissionsV0.createFinancialStatementRiskAnalysis("2019060EAI", "ES0182002030251", "AqRWQ111XX",
                evaluation);
    }
}

测试“失败”的类：

public final class ValidatorCreateFinancialStatementRiskAnalysis {

    private static final Log LOG = LogFactory.getLog(ValidatorCreateFinancialStatementRiskAnalysis.class);

    private ValidatorCreateFinancialStatementRiskAnalysis() {

    }

    public static void validateFinancialSatementEvaluationRecord(String riskAssessmentId, String participantId,
            String financialStatementId, FinancialStatementEvaluation evaluation) {

        Validate.notNull(riskAssessmentId, "riskAssessmentId");
        Validate.notEmpty(riskAssessmentId, "riskAssessmentId");

        Validate.notNull(participantId, "participantId");
        Validate.notEmpty(participantId, "participantId");

        Validate.notNull(financialStatementId, "financialStatementId");
        Validate.notEmpty(financialStatementId, "financialStatementId");

        if(evaluation == null) {
            throw new BusinessServiceException("mandatoryParametersMissing", "financialStatementEvaluation");
        }

        ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
        Validator validator = factory.getValidator();

        Set<ConstraintViolation<FinancialStatementEvaluation>> violations = validator.validate(evaluation);
        for (ConstraintViolation<FinancialStatementEvaluation> violation : violations) {
            LOG.info(violation.getMessage() + ": " + violation.getPropertyPath().toString());
            throw new BusinessServiceException(violation.getMessage(), violation.getPropertyPath().toString());
        }

    }
}

我正在使用javax.validation验证我的参数，“知道测试正确时为什么会出错吗？

1 个答案:

答案 0 :(得分：0)

问题出在此测试中：

@Test(expected = BusinessServiceException.class)
public void testObligatoryParameterIdNull() {

您期望它抛出BusinessServiceException。基本上说“该测试必须抛出此异常，否则将是测试失败”。但是它不会抛出它，而是可以正常运行。

请检查您的逻辑以查看其未引发异常的原因，或者删除(expected = BusinessServiceException.class)。
