Gradle and Arquillian Chameleon

26 February 2018

The lastest Gradle 4.6 release candiates come with BOM-import support.

It can be enabled in the settings.gradle by defining enableFeaturePreview('IMPROVED_POM_SUPPORT').

With this, the Arquillian BOM can be easily imported and the dependecies to use Arquillian with the Chameleon Adapter look like the following:

dependencies {
    providedCompile 'javax:javaee-api:7.0'

    // this is the BOM
    testCompile 'org.jboss.arquillian:arquillian-bom:1.3.0.Final'
    testCompile 'org.jboss.arquillian.junit:arquillian-junit-container'
    testCompile 'org.arquillian.container:arquillian-container-chameleon:1.0.0.Beta3'

    testCompile 'junit:junit:4.12'
    testCompile 'org.mockito:mockito-core:2.10.0'
}

Chameleon allows to easily manage the container adapters by simple configuration in the arquillian.xml. As of today, Wildfly and Glassfish are supported but not Websphere liberty.

To define Wildfly 11, the following arquillian.xml (place under src/test/resources) is sufficient:

<?xml version="1.0" encoding="UTF-8"?>
<arquillian xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://jboss.org/schema/arquillian"
    xsi:schemaLocation="http://jboss.org/schema/arquillian http://jboss.org/schema/arquillian/arquillian_1_0.xsd">

    <container qualifier="wildfly" default="true">
        <configuration>
            <property name="chameleonTarget">wildfly:11.0.0.Final:managed</property>
        </configuration>
    </container>
</arquillian>

With this little bit of Gradle and Arquillian magic, you should be able to run a test like below. The Wildfly 11 container will be downloaded on the fly.

@RunWith(Arquillian.class)
public class GreetingServiceTest {

    @Deployment
    public static WebArchive deployService() {
        return ShrinkWrap.create(WebArchive.class)
                .addClass(Service.class);
    }

    @Inject
    private Service service;

    @Test
    public void shouldGreetTheWorld() throws Exception {
        Assert.assertEquals("hello world", service.hello());
    }
}
