:imagesdir: images = The Simplest "Micro" Deployment (ArqTip #2) The second Arquillian tip is the simplest “micro” deployment. Its a Arquillian deployment that uses the hole project as deployment with no need for adding individual classes, packages or libraries: image::simplest-deployment.png[] [source,java,linenumbers] ---- @RunWith(Arquillian.class) public class SimplestDeployment { @Deployment public static Archive createDeployment() { WebArchive war = ShrinkWrap.create(ZipImporter.class, "cdi-crud.war"). importFrom(new File("target/cdi-crud.war")).as(WebArchive.class); war.addAsResource("persistence.xml", "META-INF/persistence.xml");//replace with test persistence return war; } @Inject CarService carService; @Test @UsingDataSet("car.yml") public void shouldCountCars() { assertNotNull(carService); assertEquals(carService.crud().count(), 4); } } ---- This basically uses a previously builded project as deployment and just replaces its persistence.xml to use a https://github.com/rmpestano/cdi-crud/blob/cdi-crud-universe/src/test/resources/persistence.xml[test database^]. Compare it with a https://github.com/rmpestano/cdi-crud/blob/cdi-crud-universe/src/test/java/com/cdi/crud/util/Deployments.java#L27[traditional deployment here^]. Of course that this simplicity comes with a price: . Its not a true micro deployment because it uses the hole application. If your application is big the deployment can take considerable time(seconds); . You need to build the application before running the test. Here you lose a big advantage of Arquillian which is to *not build the application if a test (even functional tests) has failed*. To overcome problem #2 you can execute the tests in surefire *integration-tests phase*: [source,xml] ---- simple-deployment maven-surefire-plugin 2.16 after-package integration-test test false **/*SimplestDeployment.java ---- There is an issue from 2012 in Arquillian issue tracker which address this feature of a “simplest deployment” using a single annotation, https://issues.jboss.org/browse/ARQ-74[see the issue here^].
