Getting PowerMock Error: java.lang.AbstractMethodError: org.powermock.api.mockito.internal.mockmaker.PowerMockMaker

Question

I am getting PowerMock error but I am not using PowerMocking. I am using normal mocking. This is my class which I want to test:

import java.util.List;

import org.apache.commons.lang.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class IlinqBeanDataBuilder {

    @Autowired
    private Settings settings;

    private static final String SERVICE_CODE_FOR_FACILITY_COUNTRY = "SERVICE_CODE_FOR_FACILITY_COUNTRY";
    private static final String SERVICE_CODE_A_CONSTANT = "A";

    private static final String HARD_DOWN = "HARD DOWN";
    private static final String QUICK_QUESTION = "QUICK QUESTION";
    private static final String PARTIAL_DOWN = "PARTIAL DOWN";

    private static final String COMPLETELY_DOWN = "Completely Down";
    private static final String UP = "Up";
    private static final String PARTIALLY_DOWN = "Partially Down";

    public RfsData prepareIlinqData(RequestData requestdata) throws FileNotFoundException {

        System.out.println("M into prepare illinq data");
        RfsData iLinkDataBean = new RfsData();
        iLinkDataBean.setCountryCode(requestdata.getCountryCode());
        iLinkDataBean.setSystemId(requestdata.getEquipmentID());
        iLinkDataBean.setModality(requestdata.getModality());
        /**
         * Removing the US from FacilityID In future fix need to change based on
         * some related information
         */
        iLinkDataBean.setCustomerId(requestdata.getFacilityID().substring(3));

        iLinkDataBean.setFirstname(requestdata.getName());
        iLinkDataBean.setPnumber(requestdata.getPhoneNumber());
        iLinkDataBean.setExtension(requestdata.getExtension());
        iLinkDataBean.setDescription(requestdata.getDescription());
        iLinkDataBean.setShortDescription(requestdata.getShortDescription());
        iLinkDataBean.setPeriod(requestdata.getTimePeriod());
        iLinkDataBean.setIlinq_local(requestdata.getLocale());
        iLinkDataBean.setRequestApp(requestdata.getRequestingApp());

        iLinkDataBean.setIsocode(requestdata.getIsoCode());
        iLinkDataBean.setProblemtype(requestdata.getProblemType());
        if (StringUtils.isNotBlank(requestdata.getEquipmentStatus())
                || StringUtils.isNotEmpty(requestdata.getEquipmentStatus())) {
            if (requestdata.getEquipmentStatus().trim().equalsIgnoreCase(HARD_DOWN)) {
                iLinkDataBean.setStatus(COMPLETELY_DOWN);
            } else if (requestdata.getEquipmentStatus().trim().equalsIgnoreCase(QUICK_QUESTION)) {
                iLinkDataBean.setStatus(UP);
            } else if (requestdata.getEquipmentStatus().trim().equalsIgnoreCase(PARTIAL_DOWN)) {
                iLinkDataBean.setStatus(PARTIALLY_DOWN);
            } else {
                iLinkDataBean.setStatus(requestdata.getEquipmentStatus());
            }
        }

        String CountryCode = iLinkDataBean.getCountryCode();
        System.out.println("Hi country code is:" + CountryCode);

        String list1 = this.settings.getString("contactge.americas.country.codes");
        System.out.println("list 1 data is:" + list1);

        String list2 = this.settings.getString("contactge.asia.country.codes");
        String list3 = this.settings.getString("contactge.europe.country.codes");
        String list4 = this.settings.getString("contactge.japan.country.codes");
        List<String> RegionList1 = Arrays.asList((list1.split(",")));
        List<String> RegionList2 = Arrays.asList((list2.split(",")));
        List<String> RegionList3 = Arrays.asList((list3.split(",")));
        List<String> RegionList4 = Arrays.asList((list4.split(",")));

        System.out.println("List1 data is:" + RegionList1);
        System.out.println("List2 data is:" + RegionList2);
        System.out.println("List3 data is:" + RegionList3);

        String RegionCode = null;
        if (RegionList1.contains(CountryCode)) {
            System.out.println("M in list 1");

            RegionCode = "Americas";

        } else if (RegionList2.contains(CountryCode)) {
            System.out.println("M in list 2");
            RegionCode = "ROA";
        } else if (RegionList3.contains(CountryCode)) {
            System.out.println("M in list 3");
            RegionCode = "EMEA";
        } else if (RegionList4.contains(CountryCode)) {
            System.out.println("M in list 4");
            RegionCode = "Japan";
        }

        System.out.println("Region code:" + RegionCode);
        iLinkDataBean.setRegionCode(RegionCode);
        System.out.println("ilinq data bean builder data:" + iLinkDataBean);

        // Getting regionCode from CountryCode using property file
        // iLinkDataBean.setRegionCode(RegionCode);
        System.out.println("system id----------------:" + iLinkDataBean.getSystemId());

        System.out.println("ilinq data bean builder data:" + iLinkDataBean);
        return iLinkDataBean;
    }
}

This is my test class. In this, I am mocking setting object which fetch data from database and I am doing inject mock at ILinqBeanDataBuilder.

        RfsData rfs = iLinqdata.prepareIlinqData(reqData);
        System.out.println(rfs.getCountryCode());

        Assert.assertEquals("CA", rfs.getCountryCode());
    }
}

I am getting this error:

Answer 1

I guess that Settings is a final class. Mockito 1.x itself cannot mock final classes and probably tries to mock them by including PowerMock - which you don't have installed.

To solve your issue, you can upgrade to at least Mockito 2.1.0 and enable the support for mocking final classes and methods . If you need to stick with an older version, either don't mock final classes, or (if you really have no other choice) give PowerMock a try.
