I have a problem :

I have two component A and B (Two wars ) :

A for storage(Neo4J) and B for search(Elasticsearch).

the communication between the components is managed by Spring Integration using HTTP Inbound/Outbound .

Here is MY configuration files for spring integration : Server A (Storage)

<int:annotation-config/> <bean class="org.springframework.integration.http.inbound.UriPathHandlerMapping"/> <int:gateway id="searchGateway" service-interface="xxxxx.IAuditSearchService"/> <int-http:outbound-gateway auto-startup="true" request-channel="sendRequest" url="http://localhost:8081/B/api/es" extract-request-payload="true"/> <int-http:inbound-gateway request-channel="searchResult" request-payload-type="xxxxx.SearchResult" path="/api/searchResult" supported-methods="POST"/> <int:object-to-json-transformer auto-startup="true" id="objectToJson" input-channel="searchRequest" output-channel="sendRequest"> </int:object-to-json-transformer> <int:json-to-object-transformer input-channel="searchReply" auto-startup="true" id="jsonToObject" output-channel="searchResult" type="xxxxxxxx.SearchResult"> </int:json-to-object-transformer> <int:channel id="searchRequest"/> <int:channel id="sendRequest"/> <int:channel id="searchReply"/> <int:channel id="searchResult"/>

In the other side : Server B : 

 <int:annotation-config/> <beans:bean class="org.springframework.integration.http.inbound.UriPathHandlerMapping"/> <int-http:inbound-gateway request-channel="searchRequest" reply-channel="searchReply" path="/api/es" request-payload-type="xxxx.AuditChange" supported-methods="POST"/> <int:gateway id="searchGateway" service-interface="xxxx.IAbSearchResult"/> <int-http:outbound-gateway auto-startup="true" request-channel="searchResult" url="http://localhost:9080/A/api/searchResult"/> <int:json-to-object-transformer id="jsonToObject" input-channel="searchRequest" type="xxxxxx.AuditChange"/> <int:object-to-json-transformer id="objectToJson" input-channel="searchReply" output-channel="searchResult"/> <int:channel id="searchRequest"/> <!--<int:channel id="esDelete"/>--> <int:channel id="searchReply"/> <int:channel id="searchResult"/>

My question :

I want to do an integration test from the server A to Server B To server A .

What's the best strategy ? It's possible to do it without mocking ? It's possible to do it without starting the servers ? (Servers A and B down)

Best Regards Nabil Belakbir

I'm not sure is this you want for integration tests.

You can use Spring mvc test framework to test inbound gateway without starting up any server.

@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = { /*omitted*/ }) @WebAppConfiguration public class HttpInboundGatewayIntegrationTests { private MockMvc mockMvc; @Autowired private WebApplicationContext wac; @Before public void setup() throws Exception { this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build(); } @Test public void testInboundGateway() throws Exception { // mockMvc.perform(get("/api/searchResult"). param("aParam", aParam). param("anotherParam",anotherParam)). andExpect(status().isForbidden()); }

But if you want to test the gateway only, you'd better sperate the spring configuration into different xmls(a-http-gateway.xml for the InboundGateway alone, for example).

On the other hand, A server has to be started up for test outbound gateway without stubbing or mocking. Maybe you are interested in https://github.com/dreamhead/moco, it's a simple framework to stub http server.

Thanks for your response . My problem is that Server A and Server B are comlettely separated . SO Spring MVC test will allow me to test the InboundGateway without starting the server A . I can do this also by testing the Gateway directelly . SO the problem is that when the server A will try to reach the server B . In this case the server B must be started or mocked . I didn't find otehr way to do this properly . Thanks also for moco It can be helpfull in my case

See the testing examples and advanced testing examples for ideas about how to test flows independently.
