tristan: about running test suite from buildstream. This is how to do it with flatpak

fork of gnome-todo with test suite (docker branch) https://github.com/albfan/gnome-todo

$ git clone https://github.com/albfan/gnome-todo
$ git checkout origin/docker
$ flatpak-builder --repo=repo todo org.gnome.Todo.Test.json
$ flatpak-builder --run todo org.gnome.Todo.Test.json gnome-desktop-testing-runner gnome-todo

Any similarities with buildstream? give me some hints please
