      - Testing Java™ applications
        You can use HCL OneTest™ API to test Java™ applications.
      - Testing Java™ Message Service (JMS) systems
        Use the generic JMS plug-in to connect HCL OneTest™ API 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 HCL OneTest™ API 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 HCL OneTest™ API 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 HCL OneTest API project and test for the services provided by the technology.
      - Testing with Apache Kafka
        Starting from HCL OneTest™ API V10.0.2 and later, you can create Kafka transports to test Kafka services.
      - Testing with Docker
        You can use Docker containers with HCL OneTest™ API to run stubs co-located with your test systems.
      - Testing with the email transport
        When you use applications in your test environment that use email services, you can use HCL OneTest™ API to create tests and stubs for testing the email services. You can set up an email transport in a HCL OneTest API project and configure the email servers as the physical resources in the HCL OneTest API project, and then test the email services.
      - Testing with Envoy Proxy (Experimental)
        You can use HCL OneTest™ API 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, which represents an abstraction of the file 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 HCL OneTest™ API to help you test trade-related messages and the systems that use them.
      - Testing with the HTTP transport
        To provide support for HTTP-based communications, you must configure and run HCL OneTest™ API by using the HTTP transport and SOAP message formatters.
        Adding a synchronization source
        You can add any of the available synchronization sources to automatically create the resources that are required for testing the API that the definition describes.
        WADL documents
        A Web Application Description Language (WADL) document is a machine-readable XML description of HTTP-based web applications (typically REST web services). WADL models the resources provided by a service and the relationships between them.
        Swagger definitions
        A Swagger definition specifies a set of metadata that describes a REST API.
        RAML definitions
        A RAML definition specifies a set of metadata that describes a REST API.
        OpenAPI 3.0 definitions
        An OpenAPI 3.0 definition specifies a set of metadata that describes a REST API.
        Common Schema Definition Language definitions
        Web services
        To provide support for HTTP-based communications and communicate with Web Services, you must configure and run HCL OneTest™ API by using the HTTP transport and SOAP message formatters.
        HTTP transport
        HCL OneTest™ API provides access to HTTP and HTTPS-based communications through an extension of its transport mechanism.
        Creating HTTP transports
        You can facilitate HTTP and HTTPS-based communications by creating physical HTTP transports.
        Creating logical HTTP connections
        In HCL OneTest™ API, tests and stubs reference the logical resources in a project. Therefore, you must create at least one logical HTTP connection for each HTTP transport that you want to use.
        Creating physical web server resources
        After you create logical HTTP connections, you must create physical web server resources and bind the logical HTTP connections to the physical resources so that you can use those resources to create tests and virtual services (stubs).
        Limitations of packet capture
        You must be aware of certain limitations of packet capture.
        Troubleshooting: HTTP and Web Services
        You can use workarounds to common problems that you might encounter when you use HTTP and Web Services.

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 HCL OneTest™ API installation program. If you want to install the Network Packet Capture feature at the time of installation of HCL OneTest™ API, you must select the Network Packet Capture option.
Note: If you want to enable the Network Packet Capture feature anytime after you install HCL OneTest™ API, you can use the Modify option in Installation Manager to modify the software package.
See Installation of 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, HCL OneTest™ API 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 HCL OneTest™ API. 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.
