错误java.lang.IllegalStateException：在JUnit中运行测试时，无法加载ApplicationContext

Question

我在使用JUnit执行统一测试时遇到问题。该应用程序由Spring Boot和具有JDK 8版本的Java组成。当我运行测试时，它显示错误“使用JUnit启动测试时加载ApplicationContext时出错”

package com.dev.loyaltyservice.loyalty.transaction.unit;

import com.dev.loyaltyservice.loyalty.transaction.domain.ActivityType;
import com.dev.loyaltyservice.loyalty.transaction.infrastructure.dataproviders.bus.ActivityIdentificationSelector;
import com.dev.loyaltyservice.loyalty.transaction.infrastructure.dataproviders.bus.response.OriginInfo;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.math.BigDecimal;

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class ActivityIdentifierTest {
    private static final String identificationCustom1 = "123124";
    private static final String identificationCustom2 = "AABBCC00";
    private static final BigDecimal total = new BigDecimal(1);
    private static final BigDecimal totalRefunds = new BigDecimal(-1);

    @Test
    public void it_should_return_custom1_value_when_is_refund_tpv() {
        String activityIdentifierCustom1 = "123124";

        OriginInfo.Activity activity = new OriginInfo.Activity(
                "",
                totalRefunds, "", 0, 0, 0, 0, activityIdentifierCustom1, null);

        String actualIdentification = ActivityIdentificationSelector.getIdentificationFrom(ActivityType.REFUND_TPV, activity);

        Assert.assertEquals(identificationCustom1, actualIdentification);
    }

    @Test
    public void it_should_return_custom2_value_when_is_refund_web() {
        String activityIdentifierCustom1 = "1231241";
        String activityIdentifierCustom2 = "AABBCC00";
        OriginInfo.Activity activity = new OriginInfo.Activity(
                "",
                totalRefunds, "", 0, 0, 0, 0, activityIdentifierCustom1,     activityIdentifierCustom2);

        String actualIdentification = ActivityIdentificationSelector.getIdentificationFrom(ActivityType.REFUND_WEB, activity);

        Assert.assertEquals(identificationCustom2, actualIdentification);
    }
}

向我显示的错误如下：执行测试时发生错误??有人知道发生了什么吗？

非常感谢您，
