我正在为处理来自 Magento 实例的新数据的 Mule 应用程序编写一个测试套件(使用 Munit)。我的流程之一是轮询 Magento 的新客户,它收到的消息类型为:com.magento.api.CustomerCustomerEntity

我想知道如何模拟它,以便在我的测试用例中,当调用 Magento 消息处理器时,我可以返回相同类型的有效负载并做出适当的断言?

目前我的 Munit 测试如下所示:

<mock:config name="mock_MagentoToSalesforce" doc:name="Mock configuration"/>
<spring:beans>
    <spring:import resource="classpath:MagentoToSalesforce.xml"/>
    <spring:bean id="myBean" name="myBean" class="com.magento.api.CustomerCustomerEntity">
        <spring:property name="email" value="test@test.com"/>
    </spring:bean>
</spring:beans>

<munit:test name="MagentoToSalesforce-test-getCustomersFlowTest" description="Test">
    <mock:when config-ref="mock_MagentoToSalesforce" messageProcessor=".*:.*" doc:name="Mock">
        <mock:with-attributes>
            <mock:with-attribute whereValue-ref="#[string:Get New Customers]" name="doc:name"/>
        </mock:with-attributes>
        <mock:then-return payload-ref="#[app.registry.myBean]"/>
    </mock:when>
    <flow-ref name="getCustomers" doc:name="Flow-ref to getCustomers"/>
</munit:test>

我要测试的流程是:

<flow name="getCustomers" processingStrategy="synchronous">
    <poll doc:name="Poll">
        <fixed-frequency-scheduler frequency="30" timeUnit="SECONDS"/>
        <watermark variable="watermark" default-expression="#[new org.mule.el.datetime.DateTime().plusYears(-30)]" update-expression="#[new org.mule.el.datetime.DateTime().plusYears(-0)]" selector-expression="#[new org.mule.el.datetime.DateTime(payload.created_at, 'yyyy-MM-dd HH:mm:ss')]"/>
        <magento:list-customers config-ref="Magento" filter="dsql:SELECT confirmation,created_at,created_in,customer_id,dob,email,firstname,group_id,increment_id,lastname,middlename,password_hash,prefix,store_id,suffix,taxvat,updated_at,website_id FROM CustomerCustomerEntity WHERE updated_at &gt; '#[flowVars.watermark]'" doc:name="Get New Customers"/>
    </poll>
    <foreach doc:name="For Each">
        <data-mapper:transform config-ref="MagentoCustomer_To_SalesforceContact" doc:name="Map Customer to SFDC Contact">
            <data-mapper:input-arguments>
                <data-mapper:input-argument key="ContactSource">Magento</data-mapper:input-argument>
            </data-mapper:input-arguments>
        </data-mapper:transform>
        <flow-ref name="upsertSalesforceContactFlow" doc:name="upsertSalesforceContactFlow"/>
    </foreach>
</flow>

按照 Ryan 的回答进行更新:

更改了表达式以返回#[ent = new com.magento.api.CustomerCustomerEntity(); ent.setEmail('test@test.com'); return [ent];]注释的有效负载,更改了方法setEmail以匹配此处的文档。我得到的错误是:

一种方法是使用构造函数或属性/设置器自己构建对象。

来自文档: http: //mulesoft.github.io/magento-connector/2.1.2/java/com/magento/api/CustomerCustomerEntity.html

<mock:then-return payload-ref="#[ent = new com.magento.api.CustomerCustomerEntity(); ent.email('test@test.com'); return ent;]"/>

您还可以将这些对象创建为可重用的 spring bean 并从 MEL 中引用它们。

    <bean class="com.magento.api.CustomerCustomerEntity" id="myEntityWithEmail">
            <property name="email" value="test@test.com" />
    </bean>

    <mock:then-return payload-ref="#[app.registry.myEntityWithEmail]"/>

更新后,我可以看到您使用了一个期望集合或可迭代的 foreach。您可以使用以下命令在 MEL 中简单地返回自定义对象的集合: [] 例如:

#[ent = new com.magento.api.CustomerCustomerEntity(); ent.email('test@test.com'); return [ent];]

更多关于 MEL 的信息:https ://developer.mulesoft.com/docs/display/current/Mule+Expression+Language+MEL

或者你可以再次使用 Spring 返回一个列表:

<util:list id="entities">
    <ref bean="myEntityWithEmail" />
</util:list>
