Injection de dépendance

14

@RunWith(Arquillian.class)public class GreeterArqIT {

@Deployment public static Archive<?> deploy() { return ShrinkWrap.create(JavaArchive.class) .addClasses(Greeter.class, Location.class) .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml"); }

@Inject Greeter greeter;

@Test public void testGreet() throws Exception { String who = "World"; String expected = "Hi " + who; String actual = greeter.greet(who);

Déploiement du composant

15

@Deployment public static Archive<?> deploy() {

return ShrinkWrap.create(JavaArchive.class)

.addClasses(Greeter.class, Location.class)

.addAsResource("config.properties")

.addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");

}

1. Créer l'archive

16

@Deployment public static Archive<?> deploy() {

return ShrinkWrap.create(JavaArchive.class)

.addClasses(Greeter.class, Location.class)

.addAsResource("config.properties")

.addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");

}

2. Ajouter du contenu

17

@Deployment public static Archive<?> deploy() {

return ShrinkWrap.create(JavaArchive.class)

.addClasses(Greeter.class, Location.class)

.addAsResource("config.properties")

.addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");

}

3. Déployer

18

@Deployment public static Archive<?> deploy() {

File[] requiredLibraries = Maven.resolver() .loadPomFromFile("pom.xml") .importRuntimeAndTestDependencies() .resolve() .withTransitivity() .asFile();

return ShrinkWrap .create(WebArchive.class) ... .addAsLibraries(requiredLibraries); }
