java - Junit中的InvalidUseOfMatchersException

问题描述

当我尝试使用 java JUnit 时，我得到了 org.mockito.exceptions.misusing.InvalidUseOfMatchersException: 异常。

代码：

@RunWith(MockitoJUnitRunner.class)
public class EmailAggregatorTest {

@Mock
private SalesOrderDAO salesDao;

@InjectMocks
private EmailAggregator emailAggregator;

@Test
public final void triggerCreditSignalConfirmationEmail() {
    Collection<Order> orders = getOrder();
    when(salesDao.getSalesOrderItems(1l)).thenReturn(getSalesOrderList());
    OrderEmail aggregateCreditSignalEmails = emailAggregator.aggregateCreditSignalEmails(orders);
    Assert.assertEquals("TRANS_OrderConf", aggregateCreditSignalEmails.getEmails().get(0).getEmailCampaignName());

}

private List<SalesOrderItem> getSalesOrderList() {
    List<SalesOrderItem> salesOrderItemList = new ArrayList<>();
    SalesOrderItem salesOrderItem = salesOrder();
    salesOrderItemList.add(salesOrderItem);
    return salesOrderItemList;
}

private SalesOrderItem salesOrder() {
    ProductCatalog productCatalog = new ProductCatalog();
    SalesOrderItem salesOrderItem = new SalesOrderItem();
    salesOrderItem.setOrderItemIdentifier(Mockito.any(Long.class));
    salesOrderItem.setProductUnitPrice(Mockito.any(String.class));
    salesOrderItem.setProductNetAmount(BigDecimal.ZERO.setScale(2, BigDecimal.ROUND_HALF_EVEN).toPlainString());
    salesOrderItem.setDiscountAmount(BigDecimal.ZERO.setScale(2, BigDecimal.ROUND_HALF_EVEN).toPlainString());
    salesOrderItem.setItemNetAmount(BigDecimal.ZERO.setScale(2, BigDecimal.ROUND_HALF_EVEN).toPlainString());
    salesOrderItem.setServiceCreditAmount(BigDecimal.ZERO);
    salesOrderItem.setTaxAmount(BigDecimal.ZERO.setScale(2, BigDecimal.ROUND_HALF_EVEN).toPlainString());
    salesOrderItem.setTaxPercentage(BigDecimal.ZERO.setScale(2, BigDecimal.ROUND_HALF_EVEN));
    salesOrderItem.setProductQuantity(1);
    productCatalog.setProductCatalogIdentifier(14625);
    salesOrderItem.setProductCatalog(productCatalog);
    return salesOrderItem;
}

private Collection<Order> getOrder() {
    List<FreeProductQueue> freeProductList = new ArrayList<>();
    FreeProductQueue freeProduct = new FreeProductQueue();
    freeProduct.setAddress1("9230 Research Blvd");
    freeProduct.setAddress2("street");
    freeProductList.add(freeProduct);
    List<Order> order = new ArrayList<Order>(
            transform(freeProductList, new ConvertFreeProductQueueToPhoenixOrderFunction()));
    SalesOrder salesOrder = new SalesOrder();
    salesOrder.setOrderIdentifier(Mockito.anyLong());
    salesOrder.addSalesOrderItem(salesOrder());
    order.stream().forEach(q -> q.addSales(salesOrder));
    return order;
}

}

例外：

    org.mockito.exceptions.misusing.InvalidUseOfMatchersException: 
Invalid use of argument matchers!
1 matchers expected, 3 recorded.
This exception may occur if matchers are combined with raw values:
    //incorrect:
    someMethod(anyObject(), "raw String");
When using matchers, all arguments have to be provided by matchers.
For example:
    //correct:
    someMethod(anyObject(), eq("String by matcher"));

For more info see javadoc for Matchers class.

解决方案

不得在 when 或 verify 调用之外使用匹配器。

在您的代码中显然不是这种情况：

salesOrderItem.setOrderItemIdentifier(Mockito.any(Long.class));
salesOrderItem.setProductUnitPrice(Mockito.any(String.class));

有关此要求的更多详细信息，请参阅Mockito 匹配器如何工作？
