Description

I'm trying to use CamelSpringDelegatingTestContextLoader with TestNG. Here's my test class:

MyTest.java

@ContextConfiguration(classes = SpringTestConfiguration.class, loader = CamelSpringDelegatingTestContextLoader.class)
public class MyTest extends AbstractCamelTestNGSpringContextTests {
    @Autowired
    private CamelContext camelContext;

    @Test
    public void test() {
        Assert.notNull(camelContext);
    }
}

Configuration class:

SpringTestConfiguration.java

@Configuration
@ComponentScan(basePackageClasses = {SpringTestRoot.class})
public class SpringTestConfiguration extends CamelConfiguration {
}

Here's the exception I'm getting:

If I drop AbstractCamelTestNGSpringContextTests and use AbstractTestNGSpringContextTests and copy the listeners I'm able to execute the test.

Will there be TestNG support for CamelSpringDelegatingTestContextLoader?
