Testing an Enterprise Information System can be a complex task, as their installation can quite complex and specific to a certain platform architecture.
As Java developers, and resource adapter developers in particularly, we are interested in a setup that will allow us to test the resource adapter against the EIS with as little difficulty as possible.
Having access to a component that easy integrates into our testing environment, and acts as the EIS in question is of benefit.
The IronJacamar EIS test server provides a framework for emulating an Enterprise Information System such that no installation is needed.
The EIS test server contains the following interface

public interface Handler
{
/**
* Handle an interaction with a client

*/
public void handle(InputStream is, OutputStream os);
}
which represents a session between the resource adapter and the EIS.
The java.io.InputStream is the incoming communication coming from the resource adapter, and
the java.io.OutputStream is the EIS' response to the request.
Once the method returns the socket between the resource adapter and the EIS is closed.
This means that the implementation of the Handler interface will represent the binary
protocol between the resource adapter and the EIS. To the resource adapter it will look as it is
communicating with the real Enterprise Information System installation.
The Apache Ant tasks for starting and stopping the EIS test server are defined as the following
<taskdef name="start"
classname="org.jboss.jca.test.eis.ant.Start"
classpathref="main.lib.path.id"/>
<taskdef name="stop"
classname="org.jboss.jca.test.eis.ant.Stop"
classpathref="main.lib.path.id"/>
where main.lib.path.id contains the ironjacamar-test-eis.jar file.
The start task is used, like
<start host="localhost" port="1400"
handler="org.jboss.jca.test.eis.EchoHandler">
<classpath>
<pathelement location="${build.eis.dir}/test"/>
</classpath>
</start>
which starts the EIS test server on localhost using port 1400 with an
implementation of the Handler interface of org.jboss.jca.test.eis.EchoHandler
and a classpath of ${build.eis.dir}/test.
The stop task is used, like
<stop host="localhost" port="1400"/>
which stops the EIS test server on localhost using port 1400.
Between the start and stop tasks the resource adapters unit tests
can be executed.
The Apache Maven mojos for starting and stopping the EIS test server are defined as the following
<build>

The start mojo will run in the process-test-classes phase, and the
stop mojo will run in the test phase.
