Contribution

It introduces a novel open-source testing system that automates test case generation and execution for payment switches, addressing limitations of existing NPCI simulators.

Findings

Automates test case generation and execution.

Supports local testing environment.

Generates comprehensive test reports.

Abstract

The Payment Switch is an integral component of all modern payment and banking systems in India. The NPCI currently provides a simulator to test payment switches. However, this system has a few disadvantages viz. it lacks an API, it requires manual generation of each test case and during high server loads, the testing process may take a long time. Currently there aren't any open source alternatives to the NPCI simulator. We propose a system which solves these shortcomings. Our proposed system simulates the NPCI system. It allows connection with switches that are to be tested and automates the process of generation and execution of test cases. It also has the capability to generate test reports and can be run locally.
