[英]Problems with unit testing a spring integration program
我正在尝试对xpath路由器进行单元测试,但是有问题。 这是我的上下文文件:
<int:channel id="toTransactionTypeRouterChannel" />
<int-xml:xpath-router id="transactionsTypeRouter"
input-channel="toTransactionTypeRouterChannel" resolution-required="false"
evaluate-as-string="true" default-output-channel="errorChannel">
<!-- Select node name of the first child -->
<int-xml:xpath-expression
expression="name(/soapNs:Envelope/soapNs:Body/schNs:processArchiveRequest/schNs:fulfillmentRequest/schNs:requestDetail/*[1])"
namespace-map="archiveNamespaceMap" />
<int-xml:mapping value="sch:bulkRequestDetail"
channel="bulkChannel" />
<int-xml:mapping value="sch:transactionalRequestDetail"
channel="transactionChannel" />
</int-xml:xpath-router>
<int:channel id="bulkChannel" />
<int:channel id="transactionChannel" />
<int:transformer input-channel="bulkChannel"
output-channel="consoleOut" expression="'Bulk channel has received the payload' " />
<int:transformer input-channel="transactionChannel"
output-channel="consoleOut" expression="'Transaction channel has received payload' " />
<int:transformer input-channel="errorChannel"
output-channel="consoleOut" expression="'Error channel has received payload' " />
如您所见,这里有2条不同的路由(批量,传输)+错误通道。这是我的跨通道路由的单元测试用例:
@Test
public void testTransactionFlow() throws Exception {
try {
Resource bulkRequest = new FileSystemResource("src/main/resources/mock-message-examples/SampleProcessArchiveTransRequest.xml");
String transRequestStr= extractResouceAsString(bulkRequest);
toTransactionTypeRouterChannel.send(MessageBuilder.withPayload(transRequestStr).build());
Message<?> outMessage = testChannel.receive(0);
assertNotNull(outMessage);
junit的上下文文件
<int:bridge input-channel="transactionChannel"
output-channel="testChannel"/>
<int:channel id="testChannel">
<int:queue/>
</int:channel>
如您所见,在junit上下文文件中,我将事务通道连接到测试通道。在junit测试用例中,我正在通过junit方法向路由器发送有效负载,并尝试从输入通道和用它来断言。 但是断言失败,因为来自事务通道的消息在转到junit coontext文件中给定的路由到inputChannel之前直接进入consoleOut。 在进入consoleOut之前如何截获消息? 我还尝试添加wireTap拦截器,但它们没有起作用:
WireTap wireTap = new WireTap(someChannel);
boolean w = wireTap.isRunning();
transactionChannel.addInterceptor(wireTap);
基本上,我需要一个单独的流程来进行单元测试。
使用该配置,您只需向transactionChannel
添加第二个使用者-消息将循环分发到转换器和网桥。
您可以通过以id
作为EventDrivenConsumer
自动装配它并在发送消息之前对其进行stop()
来取消订阅该测试用例的转换器。
