調試時失敗的JUnit是正確的

Question

我有一個包含一些JUnit測試的項目，當我嘗試使用mvn clean install package -X -e運行該項目時，我得到一個錯誤提示，說測試存在一些問題，這是出現的錯誤：

但是，如果我將項目作為JUnit測試運行，則所有測試都運行良好，並且沒有錯誤。 當我閱讀surfire-reports日志時，似乎出現了測試失敗：

但是，如果我運行該特定測試，那么它將按預期運行，這就是JUnit測試。

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);
    }
}

測試“失敗”的類：

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驗證我的參數，“知道測試正確時為什么會出錯嗎？”

Answer 1

問題出在此測試中：

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

您期望它引發BusinessServiceException 。 基本上說“此測試必須拋出此異常，否則將導致測試失敗”。 但是它不會拋出它，而是可以正常運行。

檢查您的邏輯以查看為什么它沒有引發異常，或者刪除(expected = BusinessServiceException.class) 。
