Now the route is nice and simple.
Unit testing it
Now lets turn our attention to unit testing it. From part 4 we have an unit test that is capable of exposing a webservice and send a test request and assert a mail is received. We will refactor this unit test to start up Camel, as it's Camel that should expose the webservice.
As Camel is very flexible we can create a camel context, add the routes and start it in 3 lines of code so we do it:
| Code Block |
|---|
|
protected void startCamel() throws Exception {
camel = new DefaultCamelContext();
camel.addRoutes(new ReportIncidentRoutes());
camel.start();
|
And the rest of the unit test is quite self documenting so we print it here in full:
| Code Block |
|---|
|
/**
* Unit test of our routes
*/
public class ReportIncidentRoutesTest extends TestCase {
private CamelContext camel;
// should be the same address as we have in our route
private static String ADDRESS = "http://localhost:8080/part-five/webservices/incident";
protected void startCamel() throws Exception {
camel = new DefaultCamelContext();
camel.addRoutes(new ReportIncidentRoutes());
camel.start();
}
protected static ReportIncidentEndpoint createCXFClient() {
// we use CXF to create a client for us as its easier than JAXWS and works
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setServiceClass(ReportIncidentEndpoint.class);
factory.setAddress(ADDRESS);
return (ReportIncidentEndpoint) factory.create();
}
public void testRendportIncident() throws Exception {
// start camel
startCamel();
// assert mailbox is empty before starting
Mailbox inbox = Mailbox.get("incident@mycompany.com");
assertEquals("Should not have mails", 0, inbox.size());
// create input parameter
InputReportIncident input = new InputReportIncident();
input.setIncidentId("123");
input.setIncidentDate("2008-08-18");
input.setGivenName("Claus");
input.setFamilyName("Ibsen");
input.setSummary("Bla");
input.setDetails("Bla bla");
input.setEmail("davsclaus@apache.org");
input.setPhone("0045 2962 7576");
// create the webservice client and send the request
ReportIncidentEndpoint client = createCXFClient();
OutputReportIncident out = client.reportIncident(input);
// assert we got a OK back
assertEquals("0", out.getCode());
// let some time pass to allow Camel to pickup the file and send it as an email
Thread.sleep(3000);
// assert mail box
assertEquals("Should have got 1 mail", 1, inbox.size());
// stop camel
camel.stop();
}
}

Conclusion
We have now seen how we have created a more nicer solution leveraging Camel's powerful routing capabilities.
