k6 Load Test Helper Modules

Developed a suite of JavaScript helper libraries for k6 load testing at Part Software Group. The modules accelerate scenario authoring by providing validated Iranian national IDs, IBAN numbers, retry logic, and request helpers with built-in logging — enabling the QA team to build reliable, repeatable stress tests faster.
