# Cypress Random Tester (Monkey)
2+
This repository contains the code for a random tester developed using [Cypress](https://www.cypress.io/). Two versions are developed, including a full random tester and a smarter random tester, and the differences between these two remain in the type of commands that each can execute. The detail is explained in sections below
