- Tester Guide - Integration Testing
  This guide describes the tasks that you can perform for testing various domains, technologies, and applications. To enable testing, you must configure and enable the environment for testing. This guide is intended for Integration testers.
  - Integration Testing
    You can use find information about the tasks that you can perform for testing various domains, technologies, or applications.
    - Testing Java™ applications
      You can use Rational® Integration Tester to test Java™ applications.
    - Testing Java™ Message Service (JMS) systems
      Use the generic JMS plug-in to connect Rational® Integration Tester to a wide range of EAI platforms, which includes any vendor that provides an implementation of this Java™ standard. JMS provides a way of separating the application from the transport layer of providing data. The same Java classes can be used to communicate with different JMS providers by using the JNDI information for a specific provider. The classes first use a connection factory to connect to the queue or topic, and then use populate and send or publish the messages. On the receiving side, the clients then receive or subscribe to the messages
    - Testing Java™ objects
      You can import Plain Old Java™ Objects (POJOs) from JAR files into Rational® Integration Tester in order to parse and construct messages containing the serialized forms of those objects. You can construct and parse the Java objects and perform validation, but you cannot test the objects directly.
    - Testing with Apache Camel components
      You can use Rational® Integration Tester to create tests and stubs by setting up an Apache Camel component in a Rational Integration Tester project. You can configure the technology endpoints supported by the Camel component as the physical resources in the Rational Integration Tester project and test for the services provided by the technology.

    - Testing with the email transport
      When you use applications in your test environment that use email services, you can use Rational® Integration Tester to create tests and stubs for testing the email services. You can set up an email transport in a Rational Integration Tester project and configure the email servers as the physical resources in the Rational Integration Tester project, and then test the email services.
    - Testing with Envoy Proxy (Experimental)
      You can use Rational® Integration Tester to record the HTTP traffic on the Envoy Proxy by using the Experimental HTTP Tap Filter feature of the Envoy Proxy.
    - Testing with the File transport
      As with any other transport, the File transport includes both logical and physical configurations. Tests and stubs are associated with the logical File resource, which represents an abstraction of the File resource and is the same for all environments. The physical File Access configuration includes connection details, and you can configure a different physical File Access for each environment.
    - Testing with the FIX transport
      You can use the Financial Information eXchange (FIX) transport and FIX dictionaries in Rational® Integration Tester to help you test trade-related messages and the systems that use them.
      - FIX dictionaries
        FIX dictionaries can be added to Rational® Integration Tester and applied to messages. You can then construct messages in a format that is meaningful to the system under test.
      - The FIX transport
        Rational® Integration Tester uses the Financial Information eXchange (FIX) transport to connect to applications that use the FIX protocol, acting as a client (initiator) or as a server (acceptor). Additionally, Rational Integration Tester uses packet capture software to record FIX conversations over the FIX transport.
      - Limitations of packet capture
        You must be aware of certain limitations of packet capture.
    - Testing with the HTTP transport
      To provide support for HTTP-based communications, you must configure and run Rational® Integration Tester by using the HTTP transport and SOAP message formatters.

Limitations of packet capture

You must be aware of certain limitations of packet capture.

Prerequisite

In the Library Manager, Application page, the Default Network Device field must be set to a physical interface.

Packet capture basics

Packet capture refers to the interception of a data packet as it travels across a network. Packet capture (as opposed to using an External Proxy Server) is an option when setting the Recording mode for the following transports:

TCP
FIX
HTTP

Packet capture requires specialized software:

On Windows™ systems, Network Packet Capture is not included in the Rational® Integration Tester installation program. If you want to install the Network Packet Capture feature at the time of installation of Rational® Integration Tester, you must select the Network Packet Capture option.
Note: If you want to enable the Network Packet Capture feature anytime after you install Rational® Integration Tester, you can use the Modify option in Installation Manager to modify the software package.
See Installing Rational Integration Tester.
On non-Windows systems, libpcap is typically installed by default. If necessary, you can download the latest package from http://www.tcpdump.org/.

If you choose Packet Capture as your Recording mode, Rational® Integration Tester calls the appropriate packet capture software automatically.

Limitations

Although packet capture is simpler than using an external proxy server, be aware of the following limitations:

Your system administrator might not allow the use of packet capture software due to security concerns with intercepting traffic.
On non-Windows systems, root permissions are required to access the network port in promiscuous mode, and thus to run packet capture.
Packet capture does not work with wireless network adapters. Make sure that the Default Network Device in Library Manager is set to a physical interface.
You can record only those messages that are sent from, or received by, the system running Rational® Integration Tester. You cannot record messages between remote systems.
Packet capture cannot access messages that are sent locally on a Windows™ system, because these messages go through the internal loopback connector. For more information about the internal loopback connector, see http://wiki.wireshark.org/CaptureSetup/Loopback.
