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:

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.
