Preloader image

TomEE has several arquillian adapter flavors:

  • openejb-embedded: a plain embedded OpenEJB supporting most of EE features

  • tomee-embedded: a full TomEE running in the same JVM

  • tomee-remote: a standard TomEE running in its own process as in production

  • tomee-webapp (not recommanded): an adapter starting from a Tomcat and installing tomee-webapp

Embedded or Remote?

Big advantage of embedded adapters is to be able to debug as usual. However it has few drawbacks which can make you rething this choice:

  • JVM resources are available where it will likely not be the case in war mode (src/main/resources typically)

  • You can mix server and client side features when writing a test

  • Classloading is a bit different by design and less isolated (test dependencies) so you can get runtime surprises when really deploying

To summarize: the choice is the trade off you choose between easiness and reality of the simulation.

in TomEE build we build the same tests against all tomee adapters in the same build/module, this means you can use embedded adapter in dev and activate remote tomee too (not only cause then if there is a failure you don’t know if you missed it locally or if it is due to the switch of adapter) on your continuous integration platform.
all configurations have defaults

TomEE Remote

if a server is already started on host:port then it will be used instead of starting the configured TomEE type.

To use a custom instance with arquillian ensure to have ejbd and tomee webapp activated. A way is to have in conf/system.properties these entries:

tomee.remote.support=true
openejb.system.apps=true

# you can customize it depending the security level you need on the instance
tomee.serialization.class.whitelist =
tomee.serialization.class.blacklist = org.codehaus.groovy.runtime.,org.apache.commons.collections.functors.,org.apache.xalan,java.lang.Process

For really remote instances (= not on localhost) you need the deployerProperties of previous snippet too:

Multiple instances

With arquillian you can create cluster or isolated instances. Here is a sample arquillian.xml:

<?xml version="1.0" encoding="UTF-8"?>
<arquillian xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="
    http://jboss.org/schema/arquillian
    http://jboss.org/schema/arquillian/arquillian_1_0.xsd">
 <group qualifier="tomee-cluster">
  <container qualifier="tomee-1">
   <configuration>
    <property name="httpPort">-1</property>
    <property name="stopPort">-1</property>
    <property name="ajpPort">-1</property>
    <property name="dir">target/tomee1</property>
    <property name="appWorkingDir">target/wd1</property>
   </configuration>
  </container>
  <container qualifier="tomee-2">
   <configuration>
    <property name="httpPort">-1</property>
    <property name="stopPort">-1</property>
    <property name="ajpPort">-1</property>
    <property name="dir">target/tomee2</property>
    <property name="appWorkingDir">target/wd2</property>
   </configuration>
  </container>
 </group>
</arquillian>

Then in your test just specify the container you are testing against:

@RunWith(Arquillian.class)
public class MultipleTomEETest {
 @Deployment(name = "war1", testable = false)
 @TargetsContainer("tomee-1")
 public static WebArchive war1() {
  return /* ... */;
 }

 @Deployment(name = "war2", testable = false)
 @TargetsContainer("tomee-2")
 public static WebArchive war2() {
  return /* ... */;
 }

 @Test
 @OperateOnDeployment("war1")
 public void testRunningInDep1(
    @ArquillianResource URL url) {
   // test on tomee 1, url is contextual
 }

 @Test
 @OperateOnDeployment("war2")
 public void testRunningInDep1(
    @ArquillianResource URL url) {
   // test on tomee 1, url is contextual
 }
}
