I try to use Springs own Dependency Injection in a Junit test case:
import static org.hamcrest.CoreMatchers.equalTo;
import static org.hamcrest.CoreMatchers.is;
import static org.junit.Assert.assertThat;
import org.binarisinformatik.api.AppConfig;
import org.binarisinformatik.satzrechner.SatzRechner;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes=AppConfig.class)
//@SpringApplicationConfiguration(classes = {AppConfig.class})
public class SatzRechnerTest {
@Autowired
private SatzRechner satzRechner; //SUT
@Before
public void setUp() {
// AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(SatzRechnerTest.class);
//satzRechner=context.getBean(SatzRechner.class);
}
@Test
public void addiere_satz_4komma6_zu_zahlwert_10() {
assertThat("Addition von \"4,6\" ergibt nicht 10!",
satzRechner.summe("4,6"), is(equalTo(10)));
}
Im testing a class names SatzRechner
in which Spring should also autowire some variables. Here is my Class under test:
@Component
public class SatzRechner {
@Autowired //@Inject
private Rechner taschenRechner;
@Autowired
private Zahlenfabrik zahlenfabrik;
public Integer summe(String zeichenSatz) {
return taschenRechner.summe(zahlenfabrik.erzeugeZahlen(zeichenSatz));
}
}
And AppConfig.class
which is using as Configurationfile looks like that:
@Configuration
@ComponentScan(value={"org.binarisinformatik"})
public class AppConfig {
}
What is here the problem?
