  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 Apache Kafka
      Starting from IBM® Rational® Integration Tester 10.0.2 and later, you can create Kafka transports to test Kafka services.
    - Testing with Docker
      You can use Docker containers with Rational® Integration Tester 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 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 WebSphere® Portal
      You can configure IBM® Rational® Integration Tester to synchronize IBM WebSphere® Portal resources.
    - Testing with IBM® z/OS® Connect Enterprise Edition
      IBM® z/OS® Connect Enterprise Edition provides a framework for enabling z/OS®-based programs and data to fully participate in the new API economy for mobile and cloud applications. Use IBM® z/OS® Connect Enterprise Edition to access z/OS subsystems, such as CICS®, IMS™ and Batch, by using RESTful APIs with JSON formatted messages. You can access multiple z/OS subsystems concurrently through a common interface.
    - Testing with Istio

        Synchronizing application resources of a Kubernetes cluster service in Rational® Integration Tester
        After you configure the physical connection to a Kubernetes cluster in Rational® Integration Tester, and when you want to test internal services in a Kubernetes cluster, you can synchronize the application resources of the internal service by using Rational Integration Tester. You can also select the tests and stubs that are automatically created for the operations.
        Running tests and stubs
        After you created tests and stubs in Rational® Integration Tester for the internal service of a Kubernetes cluster by using the synchronization feature, you can run the tests and stubs.
      - Publishing and running stubs in Kubernetes
        After you set up a Kubernetes cluster, you can create and publish stubs from Rational® Integration Tester to Kubernetes such that the stubs can be run in Kubernetes. The stubs published can be co-located with existing services that run in the Kubernetes cluster.
    - Testing with Microsoft™ .NET objects
      You can import serializable .NET objects from .NET assembly files (.exe or .dll) into IBM® Rational® Integration Tester and apply them to messages in the same way as you would apply a schema. A service-based test or stub can then send and receive a message containing a serialized form of a .NET object from the assembly file. You can construct and parse the .NET objects and perform validation, but you cannot test the objects directly.
    - Testing the migrated Postman collections
      You can migrate Postman collections and environments that you created in Postman to Rational® Integration Tester. Operations, transports, tests and stubs are automatically created during migration and you can run the tests and stubs in Rational Integration Tester.

Testing internal services in Kubernetes

After you set up a Kubernetes cluster, you can use Rational® Integration Tester to test internal services in Kubernetes that are not exposed through an ingress gateway to external clients.

When you set up a Kubernetes cluster that runs various services, you can use Rational® Integration Tester to create tests or stubs to test the applications or service endpoints owned by the Kubernetes services. Rational® Integration Tester supports testing of the applications that use HTTP or HTTPS transports for communication.

Prerequisites

You must have completed the setting up of the latest version of a Kubernetes cluster in your IT infrastructure and ensured that various services run in the Kubernetes cluster.

You must have a suitable kubeconfig file with access to the Kubernetes cluster in a folder on the computer on which you installed Rational® Integration Tester. The kubeconfig file must contain the following details:

The name of the service that you want to test.
The cluster IP address of the service and the port that the service uses in the cluster.
The namespace that contains the service.
Note: If you do not provide a namespace, Rational® Integration Tester considers the default value of the namespace as default.
The certificate details of the Kubernetes cluster that are required to authenticate the connection requests from Rational® Integration Tester.

Task flow for testing internal services in Kubernetes

You can find information about the tasks that you can follow to test the internal services in Kubernetes.
