    - 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.

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.

Postman

Postman is an open-source collaboration platform for API development. The platform helps to build and test APIs. The features in Postman simplify the steps for building an API and streamline the collaboration so you can create better APIs faster.

The Postman tests are grouped under an entity called Collection and a collection can have another collection as a child. Each collection can have folders and subfolders.

A Request is an entity for a REST API call. Each request can have multiple assertions that are written in the Chai BDD language and each assertion is a test in Postman.

Chai JavaScript language is the default scripting language for assert actions in Rational® Integration Tester, see Chai scripting language.

For more information about Postman, refer to the Postman documentation.

You can find information about how the Postman resources are migrated to the corresponding resources in Rational® Integration Tester in Postman resources migration.
