Use this small template to reproduce bugs in den.

Edit the rev list being tested at test.yml, include "main" and any other release tag or commit sha you might want to test. This is useful for showing regressions.

Create a minimal bug reproduction at modules/bug.nix

Each denTest is isolated from others so you can create as many as you want with same hosts and users.

Then run tests:

nix flake check

Running a single test with nixpkgs#nix-unit on PATH:

# append any attrName to run just particular tests
nix-unit --flake .#.tests.systems.x86_64-linux.system-agnostic

Please share a link to your reproduction repo, showing the CI step and the error at CI build.

If you are contributing a bug-fix PR, you can use the following command to use your local den checkout.

nix-unit  --override-input den <den-working-copy>  --flake <your-bogus-repo>#.tests.systems.x86_64-linux.system-agnostic
