Testing with IBM® WebSphere® MQ messages
You can test WebSphere® MQ messages using the WebSphere MQ transport method or JMS interface. HCL OneTest™ API also supports testing WebSphere MQ on z/OS systems.
Working with WebSphere® transports
HCL OneTest™ API creates an WebSphere® MQ transport when you create a physical WebSphere MQ Queue Manager resource in Architecture School.
Configuring WebSphere® MQ transports
After you create a WebSphere® MQ transport, you must configure it to record, send, and receive WebSphere MQ messages within HCL OneTest™ API.
Recording settings
HCL OneTest™ API provides a number of ways to record WebSphere® MQ messages.
Recording by using mirror queues mode
In Mirror Queues mode, HCL OneTest™ API uses an WebSphere® MQ API exit, which is installed on the queue manager, to take a copy of each message and put it into another queue. Therefore, if you record multiple queues, multiple mirror queues are set up.

- 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.
    - Testing with IBM® App Connect Enterprise

      - Installing and configuring HCL OneTest™ API API exits
        You can install and configure HCL OneTest™ API API exits for IBM® WebSphere® MQ.
      - Working with WebSphere® transports
        HCL OneTest™ API creates an WebSphere® MQ transport when you create a physical WebSphere MQ Queue Manager resource in Architecture School.
        Configuring WebSphere® MQ transports
        After you create a WebSphere® MQ transport, you must configure it to record, send, and receive WebSphere MQ messages within HCL OneTest™ API.
        Basic settings
        After you create a transport for WebSphere® MQ, you must configure a few basic settings associated with it.
        MQ SSL settings
        After you create a transport for WebSphere® MQ, you must configure SSL settings for it.
        Recording settings
        HCL OneTest™ API provides a number of ways to record WebSphere® MQ messages.
        Recording by using Queue browsing mode
        In Queue Browsing mode, HCL OneTest™ API uses IBM® WebSphere® MQ browse facility to capture messages.
        Recording by using proxy queues mode
        In Proxy Queues mode, HCL OneTest™ API monitors a "proxy" request queue (denoted by combining the actual queue name with the Queue Suffix), record and remove any messages that are received. It displays these messages in recording studio. Then, it passes the message on to the original queue. Request-based messages that are passed to the proxy queue are amended so that any reply queues that they specify are also converted to use the corresponding proxy queue.
        Recording by using mirror queues mode
        In Mirror Queues mode, HCL OneTest™ API uses an WebSphere® MQ API exit, which is installed on the queue manager, to take a copy of each message and put it into another queue. Therefore, if you record multiple queues, multiple mirror queues are set up.
        Recording by using Dynamic mirror queues mode
        Dynamic Mirror Queues mode is similar to Mirror Queues mode. The main difference between the two modes is that if Dynamic Mirror Queues mode is selected, WebSphere® MQ clears queues automatically. Also, when recording a shared queue in a z/OS queue sharing group, recording with dynamic mirror queues results in only messages from a single queue manager being captured. For recording a shared queue, use the Mirror Queues mode.
        Recording by using Queue aliasing mode
        An alias queue is an WebSphere® MQ object that refers to another queue. The object to which the alias is pointing can be changed without affecting the client application, which continues to reference the alias.
        Recording by using Record-the-transport mode
        To use this recording approach, you must either select the queue manager in the Architecture School Logical View and choose Add event monitor (from top or menu) or add an event monitor in Recording Studio and choose the MQ transport.
        Security settings for HCL OneTest™ API MQ alias queue recording
        If security is enabled for the queue manager, you must enable certain authorities in the queue manager for the HCL OneTest™ API MQ alias queue recording to access the HCL OneTest API alias queue.
        Stubbing settings for MQ transport
        Specify the required stubbing mode and configure the queue settings for a transport for IBM® WebSphere® MQ.
        MQ transport: Read, Write and Browse queue settings

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
      HCL OneTest™ API supports testing with Kubernetes after you set up a Kubernetes cluster. You can test the containerized applications that run as services in Kubernetes in HCL OneTest API. You can also create and publish stubs from HCL OneTest API to Kubernetes and then run the stubs in Kubernetes.
    - 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.

Recording by using mirror queues mode

In Mirror Queues mode, HCL OneTest™ API uses an WebSphere® MQ API exit, which is installed on the queue manager, to take a copy of each message and put it into another queue. Therefore, if you record multiple queues, multiple mirror queues are set up.

About this task

Note: This recording mode is available only if IBM® WebSphere® MQ 7.1 or later is installed and configured in Library Manager.

For general information about WebSphere® MQ API exits, see the WebSphere® MQ documentation. For information about deploying the API exit, see Installing and configuring HCL OneTest API API exits.

Note: When you use mirror queues to record an operation, you might encounter a race condition where the first few replies are sent before the reply queue monitor is set up. To avoid this problem, record the transport rather than the operation.

An example of the process is described in the following steps:

Procedure

Start recording on Q1.
HCL OneTest™ API (Recording Studio) configures the API exit to mirror all messages that are put onto Q1 to Q1_RIT.
The client puts message onto Q1 with the reply queue specified as Q1R.
The queue manager triggers the API exit, which puts a copy of the message onto Q1_RIT.
HCL OneTest™ API (Recording Studio) subscribes to this queue and gets the message. HCL OneTest™ API detects that message specified a reply of Q1R. HCL OneTest™ API configures the API exit to mirror all messages from Q1R to Q1R_RIT.
The server picks up the message from Q1 and replies to Q1R.
The queue manager triggers the API exit, which puts a copy of the message onto Q1R_RIT.
HCL OneTest™ API (Recording Studio) subscribes to this queue and gets the message.
The client receives the reply from Q1R.

When you stop recording, HCL OneTest™ API will, by default, delete the mirrored queue (Q1_RIT and Q1R_RIT in the example) and tell the API exit to stop mirroring. Thus, mirrored queues do not fill up with messages when you are not recording.
