Installing from apt testing

Hi guys, I am trying to get chromium-unstable installed
I am doing so because it seems not possible to get the chrome.
My objective is to execute

google-chrome-unstable --use-gl=angle --use-angle=gl --use-cmd-decoder=passthrough --enable-webgl2-compute-context

source: https://philipnoonan.github.io/wglFusion/depthColorDemo.html
but using chromium-unstable
Any ideas how to get the latter installed?
After adding testing to sourses list
I am getting

W: Skipping acquire of configured file 'testing/dep11/icons-128x128.tar' as repository 'http://ports.ubuntu.com/ubuntu-ports bionic-security InRelease' doesn't have the component 'testing' (component misspelt in sources.list?)

Hi Andrey1984,

Sorry for the late response, may I know whether this is still an issue?

Thanks

thank you for following up;
we were not able to implement it on Jetson, so we tried it with x86_64;
It is for web browser html5 intel realsense application

Understood, thanks for your update!
