Issue Description

Is there an API that can configure the D435 unit to produce a test video/depth image, instead of the actual camera image? This is useful, for example, in our application's CI system, where we want to prove that we can connect and see video from the camera without having to control what the camera is actually looking at. If the test mode always produces a specific pattern, then we can test that received data to be sure that we're seeing the expected pattern. It's fairly common for cameras to have modes that produce e.g. SMPTE test patterns -- is it possible to configure this unit in a similar way?

Hi @p-ogrady RealSense cameras do not have a test pattern mode. However, the RealSense SDK does have a text-based testing tool called rs-data-collect that will check whether frames are being received from streams without producing an image.
