I am having trouble understanding the big differences between runTest
and nixosTest
. The diffrences I know of are…
-
runTest
allows including multiple tests andnixosTest
can only be passed one test. - The various docs seem to learn towards
runTest
for any nixos related stuff (like modules) andnixosTest
for packages. And the file paths also align with this (runTest
is defined under nixos/lib/testing/default.nix andnixosTest
at pkgs/build-support/testers/default.nix
But even with that, it seems like it would easy enough to use either function to run a single or multiple test (I am making the assumption that the code to use nixosTest
to run multiple tests would be simple, someone correct me if I am wrong, especially if the purpose of runTest
is to easily run multiple tests).
Also when trying to read threw the code for both, they seem to have significant amounts of different code (even if they do share some code). While I could not quite figure what the differences are, the code leads me to assume that they are likely to have significant differences.
I want to know the significant differences because I am looking to set up testing for my nixos system configs (the “Testing outside the NixOS project” use case from manual), and I can’t decided what I should use, or why to use one over the other.
