EasyMock PowerMock IllegalStateException with Ant and not ID

Question

我正在使用带有Easymock扩展的Powermock 1.4.9。

以下是我要测试的方法

Public class SomeClass {
    public String methodToTest(String id) throws Exception {
        try {
            ClassA ojbectA = MyFactory.staticMethod();
            String str = helperMethod(id);
            ojbectA.methodA(str);
            return objectA.methodB(str);
        }
        catch (Exception e) {
            throw e;
        }
    }
}

以下是测试类和我为测试上述方法而编写的测试。我同时使用PowerMock和EasyMock，因为我有静态和私有方法调用。

import org.easymock.EasyMock;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.api.easymock.PowerMock;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import static org.easymock.EasyMock.isA;
import static org.powermock.api.easymock.PowerMock.mockStatic;
@RunWith(PowerMockRunner.class)
@PrepareForTest{{SomeClass.class,MyFactory.class, ClassA.class}}
public class TestClass {
@Test
public void testMethod1() {
    try {
        ClassA mockA = PowerMock.createMock(ClassA.class);
        mockStatic(MyFactory.class);
        SomeClass someObj = PowerMock.createPartialMock(SomeClass.class,"helperMethod");
        String mockLog = "This is sample";
        String mockId = "mockId";
        String woMockId = "WO_mockId";
        //Mock all static methods
        EasyMock.expect(MyFactory.staticMethod()).andReturn(mockA);
        //Partial mocking
        PowerMock.expectPrivate(someObj,"helperMethod",mockId).andReturn(woMockId);
        //Mock methodA(String) method
        mockA.methodA(EasyMock.isA(String.class));
        PowerMock.expectLastCall().times(0, 1);
        //When methodB(String) is called, intercept it and return a standard value.
        EasyMock.expect(mockA.methodB(isA(String.class))).andReturn(mockLog);
        EasyMock.replay(mockA);
        EasyMock.replay(someObj);
        PowerMock.replay(MyFactory.class);
        String obtainedResult = someObj.getWorkorderLogByWoId(mockId);
        assertEquals(obtainedResult,mockLog);

        EasyMock.verify(mockA);
        EasyMock.verify(someObj);
        PowerMock.verify(MyFactory.class);
    }
    catch (Exception e) {
        e.printStackTrace();
    }
}
}

这在Intellij IDEA和Eclipse上运行良好，没有任何例外。但是，当我使用 ANT 在命令行运行此测试时，出现以下异常。

有一个请求原始代码而不替换字符串。所以下面是代码。

import com.xyz.ems.common.UnitTestCase;
import com.xyz.ems.server.services.logmessage.LogMessageManager;
import com.xyz.ems.server.services.workorder.database.WorkOrderManager;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;

import static org.easymock.EasyMock.expect;

@RunWith(PowerMockRunner.class)
@PrepareForTest({WorkOrderManager.class,WorkOrderFactory.class,     LogMessageManager.class})
public class WorkOrderManagerPM_JTest extends UnitTestCase {

public WorkOrderManagerPM_JTest(String name) {
    super(name);
}
@Before
public void firstMethod() {
    assertTrue(true);
}
@After
public void lastMethod() {
    assertTrue(true);
}
@Test
public void testGetWoLogByObjectId() {
    try {
        LogMessageManager logMsgMgrMock = createMock(LogMessageManager.class);
        mockStatic(WorkOrderFactory.class);
        WorkOrderManager wMgr = createPartialMock(WorkOrderManager.class,"buildWorkOrderIdString");
        String mockLog = "This is sample";
        String mockId = "mockId";
        String woMockId = "WO_mockId";
        //Mock all static methods
        expect(WorkOrderFactory.getLogMessageManager()).andReturn(logMsgMgrMock);
        //Partial mocking
        expectPrivate(wMgr,"buildWorkOrderIdString",mockId).andReturn(woMockId);
        //Mock openLogMessageDoc() method
        logMsgMgrMock.openLogMessageDoc(isA(String.class));
        expectLastCall().times(0, 1);
        //When getAllLogMessageAsString() is called, intercept it and return a standard value.
        expect(logMsgMgrMock.getAllLogMessagesAsString(isA(String.class))).andReturn(mockLog);
        replay(logMsgMgrMock);
        replay(wMgr);
        replay(WorkOrderFactory.class);
        String obtainedResult = wMgr.getWorkorderLogByWoId(mockId);
        assertEquals("getWorkorderLogByWoId() general case passed",obtainedResult,mockLog);

        verify(logMsgMgrMock);
        verify(wMgr);
        verify(WorkOrderFactory.class);
    }
    catch (Exception e) {
        e.printStackTrace();
        fail("Failed to test getWorkorderLogById()");
    }
}

而被测的原始方法...

public class WorkOrderManager {
public String getWorkorderLogByWoId(String woId) throws WorkOrderServiceEMSException {
    try {
        LogMessageManager logMsgMgr = WorkOrderFactory.getLogMessageManager();
        String workOrderLogId = buildWorkOrderIdString(woId);
        logMsgMgr.openLogMessageDoc(workOrderLogId);
        return logMsgMgr.getAllLogMessagesAsString(workOrderLogId);
    }
    catch (Exception e) {
        String msg = "Failed to get Work Order Log for workorder Id : " + woId;
        throw new WorkOrderServiceEMSException(msg, WorkOrderServiceEMSError.WO_GET_WOLOG_BY_OBJECTID.newInstanceWithFormatArgs(woId), e);
    }
}
}
