Java EasyMock TestCase在检查异常时失败

我已经为我的代码编写了一个测试用例，使用EasyMock检查BusinessServiceException。但是测试用例失败了（不是错误）。有人能告诉我为什么会发生这种情况吗？这就是为什么这个测试用例失败的原因

Java代码：

 public class ListHelper {
    @Resource(name = "shoppingListService")
    private ShoppingListService shoppingListService;
    public void setShoppingListService(ShoppingListService shoppingListService) {
            this.shoppingListService = shoppingListService;
        }


        Public Map<String, String> getShoppingListCount(String partnerId, String userId){
                // Shopping List Section
                Map<String, String> shoppingListDetails = null;
                try {
                    shoppingListDetails = shoppingListService.getShoppingListTotal(partnerId, userId);
                } catch (BusinessServiceException e) {
                }
                return shoppingListDetails;
            }

• 您的方法不会抛出异常，因为您在空catch块中丢弃了它。

您应该将方法更改为以下内容：

public Map<String, String> getShoppingListCount(String partnerId, String userId) throws BusinessServiceException {
    // Shopping List Section
    Map<String, String> shoppingListDetails = shoppingListService.getShoppingListTotal(partnerId, userId); // do not catch the possible exception

    return shoppingListDetails;
}

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

    EasyMock.expect(shoppingListService.getShoppingListTotal("p120-90", "2012")).andThrow(new BusinessServiceException("Failure"));
    EasyMock.replay(shoppingListService);

    // pass the mock!
    ListHelper listHelper = new ListHelper(shoppingListService);

    try{
        listHelper.getShoppingListCount("p120-90", "2012");
    }finally{
        EasyMock.verify(shoppingListService);
    }
}

为什么

listHelper

而不是

shoppingListService

？您的测试用例是如何失败的？没有异常？ShoppingListService是一个接口。我正在测试的方法在ListHelper中。在失败跟踪中，它显示“java.lang.AssertionError:Expected Exception:com.优惠券.nextgen.Exception.BusinessServiceException”，您能给我们看更多代码吗？我看不出您在哪里将mock（shoppingListService）传递给测试对象（listHelper）。我会怀疑这样的事情：

listHelper=newlistHelper（shoppingListService）嗨，我上传了完整的代码…请检查一下。
@Test(expected= BusinessServiceException.class)
public void testGetShoppingListCountBusinessServiceException() throws BusinessServiceException {

    EasyMock.expect(shoppingListService.getShoppingListTotal("p120-90", "2012")).andThrow(new BusinessServiceException("Failure"));
    EasyMock.replay(shoppingListService);

    // pass the mock!
    ListHelper listHelper = new ListHelper(shoppingListService);

    try{
        listHelper.getShoppingListCount("p120-90", "2012");
    }finally{
        EasyMock.verify(shoppingListService);
    }
}
