How to use camel mock to get full XML? - unit-testing

Question

In a unit test with camel, I can make asserts using xpath to check if the output xml is correct. But instead, I'd like to use XMLUnit to validate the xml against another entire xml file. Is that possible? The following test succeeds, but I'd like to adjust it to get the actual XML.
#Test
public void testSupplierSwitch() throws Exception
{
MockEndpoint mock = getMockEndpoint("mock:market-out");
mock.expectedMessageCount(1);
EdielBean edielBean = (EdielBean)context.getBean("edielbean");
edielBean.startSupplierSwitch(createCustomer(), createOrder(), "54", "43");
assertMockEndpointsSatisfied();
}

Here is one example of how you can solve it, using mockEndpoint.getExchanges()
public class XmlUnitTest extends CamelTestSupport{
#EndpointInject(uri = "mock:market-out")
MockEndpoint marketOut;
#Override
#Before
public void setUp() throws Exception {
super.setUp();
context.addRoutes(new RouteBuilder() {
#Override
public void configure() throws Exception {
from("direct:in")
.setBody(constant("<xml>data</xml>"))
.to(marketOut.getEndpointUri());
}
});
}
#Test
public void sameXml() throws Exception {
marketOut.expectedMessageCount(1);
template.sendBody("direct:in", "body");
marketOut.assertIsSatisfied();
final String actual = marketOut.getExchanges().get(0).getIn().getBody(String.class);
final Diff diff = XMLUnit.compareXML("<xml>data</xml>", actual);
assertTrue(diff.similar());
assertTrue(diff.identical());
}
#Test()
public void notSameXml() throws Exception {
marketOut.expectedMessageCount(1);
template.sendBody("direct:in", "body");
marketOut.assertIsSatisfied();
final String actual = marketOut.getExchanges().get(0).getIn().getBody(String.class);
final Diff diff = XMLUnit.compareXML("<xml>invalid</xml>", actual);
assertFalse(diff.similar());
assertFalse(diff.identical());
}
}
