How can I test a new app feature in a Shopify development environment?

[yaser-alazm]

Hello,

I'm a developer and I have an already developed app for Shopify. The app is developed with JavaScript as a full stack (MERN Stack).

 The app is already working on my local machine. Backend API built using NestJs (Express/NodeJs) and the frontend app is a NextJs (ReactJs) app .

What I want exactly is to test a new feature I already developed for the app, the development environment is on my local machine and I need to test new feature on a development environment for Shopify ( installing the app on Dev Env of Shopify and login to my Dev Env app).

I couldn't find a way to implement the testing in the right way, hoping that I can find a helpful answer here.

Thanks in advanced.
