Arquillian Liberty Managed

An Arquillian container adapter (DeployableContainer implementation) that can start and stop a local Liberty process and run tests on it over a remote protocol (effectively in a different JVM).

Prerequisites

Prerequisite Version

This DeployableContainer has been tested with the latest two releases of Open Liberty and WebSphere Liberty. Requires Java EE 8 or below.

For Jakarta EE 9 projects, check out the documentation here.

Prerequisite Configuration

The following features are required in the server.xml of the Liberty server.

<!-- Enable features -->
<featureManager>
    <feature>jsp-2.3</feature>
    <feature>localConnector-1.0</feature>
    <feature>j2eeManagement-1.1</feature> <!-- Optional, needed to allow injection on ArquillianResources related to servlets -->
    <feature>usr:arquillian-support-1.0</feature> <!-- Optional, needed for reliable reporting of correct DeploymentExceptions -->
</featureManager>

Read more about configuring the arquillian-support-1.0 feature here.

You will also need to enable the applicationMonitor MBean support in your server.xml:

<applicationMonitor updateTrigger="mbean"/>

If you need a sample server.xml, please refer to the one in our source repository.

Configuration

Default Protocol: Servlet 3.0

To enable Arquillian Liberty Managed in your project, add the following to your pom.xml:

<dependencyManagement>
	<dependencies>
		<dependency>
			<groupId>org.jboss.arquillian</groupId>
			<artifactId>arquillian-bom</artifactId>
			<version>1.4.0.Final</version>
			<scope>import</scope>
			<type>pom</type>
		</dependency>
	</dependencies>
</dependencyManagement>

<dependencies>
	...
	<dependency>
		<groupId>io.openliberty.arquillian</groupId>
		<artifactId>arquillian-liberty-managed</artifactId>
		<version>1.0.6</version>
		<scope>test</scope>
	</dependency>
	...
</dependencies>

Container Configuration Options

Name Type Default Description
wlpHome String None Home directory of the WLP runtime.
serverName String defaultServer Name of the server to start.
httpPort Integer 9080 HTTP Port of the server.
javaVmArguments String None JVM Arguments to pass into the WLP runtime.
deployType String dropins Type of deployment (available: dropins or xml)
sharedLib String None ID of the shared library reference; if provided it will be used as the commonLibraryRef attribute of the application/classloader configuration element
securityConfiguration String None When using xml deployType the referred file will be embedded within the application tag into the server.xml and should be used to configure the security settings.
failSafeUndeployment String None In some scenarios the xml deployType deployments might fail to undeploy because of an open FileHandle on Windows when using an Oracle JVM. Enabling this flag suppresses the exception to be thrown and marks the file to be delete upon exiting the JVM process.
apiTypeVisibility String None String that will be set as the apiTypeVisibility attribute of the application/classloader configuration element. See the WLP Knowledge Center for possible values and default used when this value is not provided.
verifyApps String None Specifies a comma-separated list of names of applications that will be verified to be started before tests are executed
verifyAppDeployTimeout Integer 20 Time in seconds to wait for the verifyApps application deployment to complete and the applications to start
serverStartTimeout Integer 30 Time in seconds to wait for the application server to start
serverStopTimeout Integer 30 Time in seconds to wait for the application server to stop
appDeployTimeout Integer 20 Time in seconds to wait for the application deployment to complete and the application to start
appUndeployTimeout Integer 2 Time in seconds to wait for the application undeployment to complete
allowConnectingToRunningServer Boolean false Allow a connection to be made to an already running application server process
outputToConsole Boolean true When enabled output from the application server process will be emitted to stdout
fileDeleteRetries Integer 30 How many times to attempt deleting a file
standardFileDeleteRetryInterval Integer 50 How long in milliseconds to wait between attempting to delete a file
