以遞歸方法使用EasyMock

Question

我正在使用EasyMock 3.2生成的一系列Strict Mocks來遞歸調用自身的方法。通過設置我的嘲笑的期望，我可以控制該方法，使其只調用一次，然後退出。但是，我看到EasyMock中的一些非常奇怪的行爲，看起來像一個錯誤，它讓人對預計方法的次數感到困惑。

例如：

final Collection srcCollection = EasyMock.createStrictMock(Collection.class); 
final NativeBroker broker = EasyMock.createMockBuilder(NativeBroker.class) 
    .addMockedMethod("getCollection") 
    .addMockedMethod("getSubject") 
    .createStrictMock(); 

expect(srcCollection.getURI()).andReturn(src); 

replay(srcCollection, broker); 

//run the test 
broker.checkPermissionsForCopy(srcCollection, dest, newName); 

verify(srcCollection, broker); 

信息從EasyMock的錯誤：

java.lang.AssertionError: 
    Expectation failure on verify: 
     Collection.getURI(): expected: 2, actual: 1 
     at org.easymock.internal.MocksControl.verify(MocksControl.java:226) 
     at org.easymock.EasyMock.verify(EasyMock.java:2080) 

我只指示EasyMock的期望一個結果，爲何還以爲我想要兩個？我也得到了同樣的錯誤，如果我改變我的期望，這樣的：

expect(srcCollection.getURI()).andReturn(src).once(); 

...它得到的陌生人......

如果我改變我的期望，這樣的：

expect(srcCollection.getURI()).andReturn(src).times(2); 

我得到的錯誤：

java.lang.AssertionError: 
    Expectation failure on verify: 
     Collection.getURI(): expected: 3, actual: 1 
     at org.easymock.internal.MocksControl.verify(MocksControl.java:226) 
     at org.easymock.EasyMock.verify(EasyMock.java:2080) 

而且，如果進一步更改我的期望，這樣的：

expect(srcCollection.getURI()).andReturn(src).anyTimes(); 

我得到一個更奇怪的錯誤：

java.lang.IllegalStateException: last method called on mock already has a non-fixed count set. 
    at org.easymock.internal.MocksControl.replay(MocksControl.java:216) 
    at org.easymock.EasyMock.replay(EasyMock.java:2012) 

沒有人有任何建議或知道的遞歸函數與EasyMock的任何限制？

我看不出這段代碼有什麼問題。

經紀人的兩個模擬方法是否被期望不被調用？

我做了一個測試用例。你能讓它失敗嗎？

public class AppTest { 

public static interface Collection { 
    String getURI(); 
} 

public static class NativeBroker { 

    public void checkPermissionsForCopy(Collection srcCollection, String dest, 
      String newName) { 
     srcCollection.getURI(); 
    } 

    public Collection getCollection() { 
     return null; 
    } 

    public String getSubject() { 
     return null; 
    } 
} 

String src = "http://src.com"; 
String dest = "http://dest.com"; 
String newName = "my name"; 

@Test 
public void testApp() { 
    final Collection srcCollection = EasyMock.createStrictMock(Collection.class); 
    final NativeBroker broker = EasyMock.createMockBuilder(NativeBroker.class) 
      .addMockedMethod("getCollection") 
      .addMockedMethod("getSubject") 
      .createStrictMock(); 

    expect(srcCollection.getURI()).andReturn(src); 

    replay(srcCollection, broker); 

    // run the test 
    broker.checkPermissionsForCopy(srcCollection, dest, newName); 

    verify(srcCollection, broker); 
}}

在我的情況下，我重複相同的期望值2次。它拋出：

java.lang.IllegalStateException：在mock上調用的最後一個方法已經有一個非固定的計數集。

E.G.

SchedulingDataForVersion dataForVersion = createNiceMock(SchedulingDataForVersion.class); 
TaskSource mockedTaskSource = createNiceMock(TaskSource.class); 

    expect(mockedTaskSource.getOrderElement()).andReturn(orderLine).anyTimes(); 
    expect(mockedTaskSource.getOrderElement()).andReturn(orderLine).anyTimes(); 

    replay(dataForVersion, mockedTaskSource); 

正確之一是：

SchedulingDataForVersion dataForVersion = createNiceMock(SchedulingDataForVersion.class); 
TaskSource mockedTaskSource = createNiceMock(TaskSource.class); 

    expect(dataForVersion.getOrderElement()).andReturn(orderLine).anyTimes(); 
    expect(mockedTaskSource.getOrderElement()).andReturn(orderLine).anyTimes(); 

    replay(dataForVersion, mockedTaskSource
