I have a maven project which i'm using MapStruct to generate mappers to help in the job of translating entities into DTOs and vice-versa. This mappers are generated during the generate-sources phase of maven, and stored into target/generated-sources and target/AppName/WEB-INF/classes folders.
For example, I have this Mapper
@Mapper
public interface RuleMapper {
RuleDto ruletoDto(Rule rule);
//other cool stuf
}
I configurated MapStruct to use CDI, so it will generate the following:
@Generated(
value = "org.mapstruct.ap.MappingProcessor",
date = "2016-12-19T23:19:36-0200",
comments = "version: 1.1.0.CR1, compiler: javac, environment: Java 1.8.0_112"
)
@Singleton
@Named
public class RuleMapperImpl implements RuleMapper {
@Override
public RuleDto ruletoDto(Rule rule) {
ruleDto ruleDto = new ruleDto();
if ( rule != null ) {
ruleDto.setIdRule( rule.getIdRule() );
}
return ruleDto;
}
}
It works perfectely when running on Wildfly server, the problem is that I'm trying to junit test this class, for this, I implemented a custom runner as shown bellow:
import org.junit.runners.BlockJUnit4ClassRunner;
import org.junit.runners.model.InitializationError;
public class WeldJUnit4Runner extends BlockJUnit4ClassRunner {
public WeldJUnit4Runner(Class<Object> clazz) throws InitializationError {
super(clazz);
}
@Override
protected Object createTest() throws Exception {
final Class<?> test = getTestClass().getJavaClass();
return WeldContext.INSTANCE.getBean(test);
}
}
And:
import org.jboss.weld.environment.se.Weld;
import org.jboss.weld.environment.se.WeldContainer;
public class WeldContext {
public static final WeldContext INSTANCE = new WeldContext();
private final Weld weld;
private final WeldContainer container;
private WeldContext() {
this.weld = new Weld();
this.container = weld.initialize();
Runtime.getRuntime().addShutdownHook(new Thread() {
@Override
public void run() {
weld.shutdown();
}
});
}
public <T> T getBean(Class<T> type) {
return container.instance().select(type).get();
}
}
These implementations were taken from here.
Finally, the test:
@RunWith(WeldJUnit4Runner.class)
public class RuleMapperTest {
@Inject
private RuleMapper ruleMapper;
@Test
public void coolTestName() {
Assert.assertTrue(Boolean.TRUE);
}
}
When I try to run, this is the console output:
log4j:WARN No appenders could be found for logger (org.jboss.logging). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
warning about logs, and the following exception:

Like Weld wasn't abble to lookup the generated class.
The beans.xml
is already created under src/test/resources/META-INF/beans.xml
:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"

version="1.1" bean-discovery-mode="all">
</beans>
Can anybody point me a solution to this problem? I've already searched something simillar, but no success.
