# Properties Using `nix`. Where `o` is `open` on OSX and `xdg-open` on linux, ```sh nix-build o result/property-tests.pdf ``` Without `nix`, you can install `pandoc` yourself and run ```sh pandoc -s property-tests.md -o property-tests.pdf ``` ## _Details_ The `property-tests.pdf` document is _normative and aspirational_. It does not document tests as they exist in the codebase, but somewhat represents how we think squiggle ought to be tested.
