arquillian using a random port with tomcat7 embeded - jboss-arquillian

Question

I'd like to use a random port for arquillian.
So in arquillian.xml
I do:
<arquillian>
<container qualifier="tomcat7" default="true">
<configuration>
...
<property name="bindHttpPort">0</property>
...
</configuration>
</container>
</arquillian>
In my unit test:
#ArquillianResource
private URL base;
I hope to have the real port (localPort) used by Apache Tomcat (because yes it start with a random port) but this URL is with 0 port the one from configuration not random one.
So how to have access to this?

Answer 1

Are you using Apache Maven to run such tests ?
Here is how I did. On Maven side I'm using the buildhelper plugin and surefire to define the random port and pass it to tests as a system property
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<executions>
<execution>
<id>reserve-network-port</id>
<phase>initialize</phase>
<goals>
<goal>reserve-network-port</goal>
</goals>
<configuration>
<portNames>
<portName>tomcat.http.port</portName>
</portNames>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<systemProperties>
<!-- Port used for Tomcat HTTP connector -->
<tomcat.http.port>${tomcat.http.port}</tomcat.http.port>
</systemProperties>
</configuration>
</plugin>
</plugins>
And then I configured arquillian with
<arquillian>
<container qualifier="tomcat" default="true">
<configuration>
<property name="bindHttpPort">${tomcat.http.port:9090}</property>
</configuration>
</container
</arquillian>
Note : I'm using a default value for the port for when I'm launching the test from my IDE to avoid to have to manually configure it.

You can use the arquillian-available-port-extension.
Simply add the dependency in your pom
<dependency>
<groupId>com.github.mryan43</groupId>
<artifactId>arquillian-available-port-extension</artifactId>
<version>${arquillian-available-port-extension.version}</version>
</dependency>
and put in your arquillian.xml :
<property name="bindHttpPort">${available.port}</property>
This has the advantage of working both when running in maven and when running in your IDE.
