Scaffolding IRIS REST API Tests with IrisOASTestGen

Project Overview / Introduction

Developing and testing REST APIs in InterSystems IRIS often requires a significant amount of boilerplate code. While ObjectScript provides powerful tools for building APIs, writing consistent and repeatable tests can be time‑consuming. This is where IrisOASTestGen comes in.

My experience with APIs and POS integration.

Hola amigo! 😊 Cómo estás hoy,

I would like to share a small part of my learnings from my first ever official project: POS/EDC machine integration with our billing system. This was an exciting challenge where I got hands-on experience working with APIs and vendors.

How does a Payment Machine actually work?

It's simple, start by initiating/creating a transaction, then retrieve its payment status.

Here, initiate/create refers to POST method and Retrieve refers to GET.

Macroses with variable number of optional arguments

Hi,

I need a simple function for formatting a string, like in Python or C#. That's easy:

Class Very.Very.Long.Class.Name
{
ClassMethod Format(fmt As %String, args...) As %String [ Language = python ]
{
return fmt.format(*args)
}
}

To simplify calls, I want to wrap the function into a macro:

Customizing API Test Code Generation with Mustache Templates

The previous article introduced IrisOASTestGen, a tool designed to generate REST API test code for InterSystems IRIS based on OpenAPI 2.0 specifications. It demonstrated how to scaffold test cases using the default templates bundled with OpenAPI Generator.

This follow-up focuses on the next natural step: customizing the generated test code.
By extending the code generation logic with Mustache templates, it becomes possible to express richer semantics, implement CRUD-aware tests, and create more meaningful test suites.
