RenderingTest

Show deprecated

RenderingTest is an internal testing utility used by Roblox engineers to do performance/regression tests on the rendering pipeline. It is expected to be parented inside of the TestService, and will run LocalScripts parented inside of it when the TestService is ran via TestService/Run.

Selected RenderingTest

One of its more notable features is that, upon being selected in the Explorer, it draws an accurate wireframe of the Camera frustum, visualizing what a Camera would see in the RenderingTest’s configuration.

Recording Test Results

When a RenderingTest is executed by the TestService, the Workspace/CurrentCamera|CurrentCamera of the Workspace has its properties updated so it mirrors the Camera configuration of the RenderingTest.

The recorded data is then sent as JSON with an HTTP-POST request to: localhost:8001/api/v1/submit_test.

For the RenderingTest to pass in Roblox Studio, the request expects the response to be the string "passed". It will also acknowledge the strings "failed" or "golden" as a string response.
