Apparently this looks like it was forgotten when doing commit 3884ff70badca0c93c717e6190946a9a2846e948, which refactored the test runner and driver a bit. The passthru argument actually was correctly reintroduced in setupDriverForTest, but the actual makeTest function didn't use it. This fixes the nixpkgs tarball job, which previously failed with: attribute 'elkPackages' missing, at /build/source/pkgs/tools/misc/logstash/6.x.nix:58:30 Signed-off-by: aszlig <aszlig@nix.build> Acked-by: David Arnold <dar@xoe.solutions> Fixes: https://github.com/NixOS/nixpkgs/issues/127274 Merges: https://github.com/NixOS/nixpkgs/pull/127346
