Switch CI to Nix flakes
We also move tests to Flakes. This would allow users to submit PRs with a fork of nixpkgs when they want to test nixpkgs PRs against SNM.

Run NixOS tests
|
||||
---------------
|
||||
|
||||
You can run the testsuite via
|
||||
To run the test suite, you need to enable `Nix Flakes
|
||||
<https://nixos.wiki/wiki/Flakes#Installing_flakes>`.
|
||||
|
||||
You can then run the testsuite via
|
||||
|
||||
::
|
||||
|
||||
$ nix-build tests -A external.nixpkgs_20_03
|
||||
$ nix-build tests -A internal.nixpkgs_unstable
|
||||
...
|
||||
$ nix flake check -L
|
||||
|
||||
Since Nix doesn't garantee your machine have enough resources to run
|
||||
all test VMs in parallel, some tests can fail. You would then haev to
|
||||
run tests manually. For instance:
|
||||
|
||||
::
|
||||
|
||||
$ nix build .#hydraJobs.x86_64-linux.external-unstable -L
