# Workflow for triggering `test-manager` on select platforms.
#
# This is a rather complex workflow. The complexity mainly stems from these sources:
# * figuring out which platforms to test on which runners (prepare-matrices)
# * figuring out if the app and e2e-tests should be built on the runner (build-{linux,windows,macos})
# or if we should download the artifacts from https://releases.mullvad.net/desktop/
# * compiling the output from the different runners and executed platforms.
