Software testing is an investigation conducted to provide stakeholders with information about the quality of the software product or service under test.

Target Practice for IrisClusters with KWOK

KWOK, Kubernetes WithOut Kubelet, is a lightweight tool that simulates nodes and pods—without running real workloads—so you can quickly test and scale IrisCluster behavior, scheduling, and zone assignment. For those of you wondering what value is in this without the IRIS workload, you will quickly realize it when you play with your Desk Toys awaiting nodes and pods to come up or get the bill for provisioning expensive disk behind the pvc's for no other reason than just to validate your topology.

Here we will use it to simulate an IrisCluster and target a topology across 4 zones, implementing high availability mirroring across zones, disaster recovery to an alternate zone, and horizontal ephemeral compute (ecp) to a zone of its own. All of this done locally, suitable for repeatable testing, and a valuable validation check mark on the road to production.

Overview I'm excited to announce the release of testcontainers-iris-node, a Node.js library that makes it easy to spin up temporary InterSystems IRIS containers for integration and E2E testing. This project is a natural addition to the existing family of Testcontainers adapters for IRIS, including testcontainers-iris-python and testcontainers-iris-java.

Why testcontainers-iris-node? As a Node.js developer working with InterSystems IRIS, I often faced challenges when setting up test environments that mimic production. testcontainers-iris-node solves this by leveraging the testcontainers-node framework to create isolated IRIS environments on-demand.

This is particularly valuable for:

  • Integration testing with IRIS databases
  • Testing data pipelines or microservices
  • Automating test environments in CI pipelines

Features

  • Launches IRIS in Docker containers using Testcontainers
  • Supports custom Docker images and configuration
  • Wait strategies to ensure IRIS is ready before tests begin
  • Clean teardown between test runs

The new version of InterSystems Testing Manager which I released last week brings @Timothy Leavitt's cool
Test Coverage Tool to VS Code, and is my entry for the 2025 Developer Tools contest.

Here's a teaser screenshot showing how the unit tests of the IPM project don't yet cover a feature that apparently allows an IPM repository to override its sort order.

Now that we have a good understanding of Python and its features, let's explore how we can leverage Python within IRIS.

Are you curious about how to run Python scripts directly in your InterSystems IRIS or Caché terminal? 🤔 Good news it's easy! 😆 IRIS supports Embedded Python, allowing you to use Python interactively within its terminal environment.

How to access the Python Shell?

To launch the Python shell from the IRIS terminal, simply run the following command:

Hey Community,

Last week, the InterSystems team held our monthly Developer Meetup in a new venue for the first time ever! In the AWS Boston office location in the Seaport, over 71 attendees showed up to chat, network, and listen to talks from two amazing speakers. The event was a huge success; we had a packed house, tons of engagement and questions, and attendees lining up to chat with our speakers afterwards!

At hackathons that InterSystems participated and I supported, many students were asking how all their teammates could use the same IRIS database that they spun up in a container. I suggested using ngrok to expose their localhost IRIS and realized we don't have documentation on that. Hence, I thought this would be great to let more people knwo about this powerful technique for enhancing collaboration during development and testing.

Hi folks!

I'm building a very simple REST API.

But before testing it via a Web Server what I want to make sure that REST API methods work in principle.

Is it an easy way to "fake" the web-server request and get a result e.g. of the method with signature like that?

ClassMethod GetAllRecords(pRequest As %CSP.Request, pResponse As %CSP.Response) As %Status

e.g. calling it in Terminal?

Hello all!
We fully tested our system http://DataAI.link on InterSystems Cache database and on old IRIS.
We cannot find a free download of IRIS for developer as it was before.
We are looking for help from the community to test our system from the http://DataAI.link by register a user with connection to your testing IRIS database and play with our reports, analytics, AI.

Hi Community,

In this article, I will introduce my application iris-HL7v2Gen .

IRIS-HL7v2Gen is a CSP application that facilitates the dynamic generation of HL7 test messages. This process is essential for testing, debugging, and integrating healthcare data systems. The application allows users to generate a wide variety of HL7 message types, validate their structure against HL7 specifications, explore the message hierarchy, and transmit messages over TCP/IP to production systems. These features are particularly useful in settings where compliance with HL7 standards is mandatory for interoperability between different healthcare organizations or systems.


Application Features

  • Dynamic HL7 Message Generation: Instantly create HL7 messages for a range of message types, facilitating comprehensive testing.
  • Message Structure Exploration: Visualize the structure of generated messages based on HL7 specifications.
  • Value Set Visualization View predefined sets of allowable coded values for specific fields.
  • Message Validation: Validate messages against HL7 standards to ensure compliance.
  • TCP/IP Communication: Easily transmit messages to production using TCP/IP settings.
  • Broad Message Type Support: Supports 184 different HL7 message types, ensuring versatility for various healthcare integration needs.
  • ClassMethod: Generate a Test Message by Invoking a Class Method
  • Version Support: Currently Supports HL7 Version 2.5
