Testing & VM Integration

Testing a greeter locally can be tricky since it requires a Wayland compositor and the greetd daemon running as root.

mdgreet solves this by providing a fully configured, containerized NixOS Virtual Machine.

Running the Test VM

If you have Nix installed, you can spin up the test VM directly from the flake. This VM includes dummy users, a compositor (cage), and is configured to run your local build of mdgreet.

nix run .#vm

This command will:

1. Compile mdgreet.
2. Build a minimal NixOS qcow2 image.
3. Launch QEMU with graphical support.

You can log in using any of the test users (e.g., alice, bob) with the password password.

Running Unit Tests

We use standard Cargo tests for non-UI business logic (like theme parsing).
