TestEZ Companion is an open source Visual Studio Code extension that enables Roblox developers to preview their TestEZ unit test results right inside their editor.

To communicate between the Visual Studio Code and Roblox Studio, a custom plugin has been made, communicating using an unit tested HTTP server.

Companion is a tool I made and use frequently when dealing with more sensitive routines. Without it, unit testing would be a slower and less easy to use experience for the developer.

The Code extension is made using tools such as:

• Jasmine (unit testing)
• Webpack (bundling)
• Fastify (HTTP server)
• AJV (schema validation)
• Redux (managing extension state)

At the time of writing, TestEZ Companion has over 1,000 installations and a 5 Star rating on the Microsoft Store.
