- Tester Guide - API 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 API testers.
  - API 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 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 an HCL OneTest API 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 10.0.2 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 an 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 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 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.
    - Testing with IBM® API Developer Portals
      You can configure HCL OneTest™ API to synchronize IBM API Connect™ Developer Portal resources or IBM® API Management Developer Portal resources.

      When you want to test the services on applications deployed by the integration node of IBM® App Connect Enterprise, you can use the synchronization feature in HCL OneTest™ API to import details of deployed applications into an HCL OneTest API project. You can select the tests and stubs to be created in your project during the synchronization process in HCL OneTest API.
    - Testing with IBM® Integration Bus
      When you want to test the services on applications deployed by the integration node of IBM® Integration Bus, you can use the synchronization feature in HCL OneTest™ API to import details of deployed applications into an HCL OneTest API project. You can select the tests and stubs to be created in your project during the synchronization process in HCL OneTest API.
    - Testing with IBM® WebSphere® Application Server
      You can configure HCL OneTest™ API to synchronize IBM® WebSphere® Application Server resources.
    - Testing with IBM® WebSphere® MQ messages

      - Working with WebSphere® MQ messages
        You can create publishers and subscribers to send and receive IBM® WebSphere® MQ messages in HCL OneTest™ API.
        WebSphere® MQ message formats
        In order that a receiving system can best interpret the received payload, WebSphere® MQ can indicate the format of user data. User data can contain one or more blocks that can be chained together. Each block includes the format of the next item in the chain. The last block is the user data.
        Messages send request
        MQ messages are sent by using the Send Request action in HCL OneTest™ API tests. The following provides information about how to configure a send request that uses the MQ transport.
        Messages publication
        MQ messages are put on to queues by using the Publish action in HCL OneTest™ API tests.
        Subscribing to messages
        You can retrieve MQ messages from a queue by using the Subscribe action in HCL OneTest™ API tests.
        Creating subscribe actions
        You can create a subscribe action in HCL OneTest™ API Test Factory perspective.
        Selecting the transport and formatter
        You can select the transport and formatter for a Subscribe action.
        Subscribing to MQ messages
        Subscribing to MQ messages requires only the name of the local queue from which messages are reviewed or retrieved. More filtering options, however, are available if needed.
      - Troubleshooting: Websphere MQ
        You can use workarounds to problems that you might encounter when you use IBM® WebSphere® MQ with HCL OneTest™ API.
    - Testing with WebSphere® Portal
      You can configure HCL OneTest™ API to synchronize IBM® WebSphere® Portal resources.

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
      When you have applications hosted in a Kubernetes cluster that have Istio as a service mesh, you can virtualize the services in the cluster by creating stubs and tests for testing with Istio in HCL OneTest™ API.
    - Testing with Kubernetes
      For testing with Kubernetes set up a Kubernetes cluster, and then you can create and publish stubs from HCL OneTest™ API so that stubs can be run within Kubernetes. The stubs published can be co-located with existing services running within the Kubernetes cluster.
    - Testing with Microsoft™ .NET objects
      You can import serializable .NET objects from .NET assembly files (.exe or .dll) into HCL OneTest™ API 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 HCL OneTest™ API. Operations, transports, tests and stubs are automatically created during migration and you can run the tests and stubs in HCL OneTest API.
