如何在测试方法中简化 mockito/hamcrest 参数匹配器？

Question

下面的测试方法出现在spring-guide 教程中。是否有一个不太复杂的语法来编写这个测试，或者我怎样才能把它分解成更小的块？

verify(orderService).createOrder(
      org.mockito.Matchers.<CreateOrderEvent>argThat(
        allOf( org.hamcrest.Matchers.<CreateOrderEvent>
            hasProperty("details",
                hasProperty("dateTimeOfSubmission", notNullValue())),

        org.hamcrest.Matchers.<CreateOrderEvent>hasProperty("details",
                hasProperty("name", equalTo(CUSTOMER_NAME))),

        org.hamcrest.Matchers.<CreateOrderEvent>hasProperty("details",
                hasProperty("address1", equalTo(ADDRESS1))),
        org.hamcrest.Matchers.<CreateOrderEvent>hasProperty("details",
                hasProperty("postcode", equalTo(POST_CODE)))
    )));

Answer 1

您可以切换 hasProperty 和 allOf 匹配器。

verify(orderService).createOrder(
      org.mockito.Matchers.<CreateOrderEvent>argThat(
        org.hamcrest.Matchers.<CreateOrderEvent>hasProperty("details",
          allOf(
            hasProperty("dateTimeOfSubmission", notNullValue()),
            hasProperty("name", equalTo(CUSTOMER_NAME)),
            hasProperty("address1", equalTo(ADDRESS1)),
            hasProperty("postcode", equalTo(POST_CODE)))
    )));
