jMock injection

agattik Oct 16, 2008 5:03 PM

The reference documentation has a paragraph on injecting mock classes. Is there a way to inject dynamic mocks like those created with jMock?

Here's an example dynamic mock that I would like to inject. Unwrapping all that logic to a full-blown class would be much less concise.

Mockery context = new Mockery();
final OntologyDataFactory factory = context.mock(OntologyDataFactory.class);
context.checking(new Expectations() {
     {
          atLeast(1).of(factory).createOntologySource(null, source);
          will(returnValue(ontologySource));

          atLeast(1).of(factory).createOntologyIndividual(
                    with(ontologySource), with(any(String.class)),
                    with(any(String.class)));
          will(returnValue(ontologyIndividual));
     }
});

Sorry for not answering that fast but... it might help others...
we found a solution here that works fine...
Suppose you have a CustomerDAO in your src/main folder under com.my.customer.CustomerDAO...
Code a MockCustomerDAO on your src/test folder under the same package as follows

public class MockCustomerDAO { public static CustomerDAO customerDAO; @Unwrap public CustomerDAO getCustomerDAO() { return customerDAO; } }

The tricks are:

Dont annotate the Mock class otherwise if you are using WTP and run it directly you'll get your mock class instead of your real class

declare a static field and let seam inject this instance instead of the Mock Class using the @Unwrap annotation

The next step is to configure the mock component with the same name of the real annotated component on the components.xml under src/test/resources with the mock precedence of 40.

This solution follows the premise that your test suite will load the components.xml under src/test/resources/WEB-INF and your development Tomcat on WTP will use src/main/resources.

Hope this helps,
