snapshot

Set PLUSHIE_UPDATE_SNAPSHOTS=1 to force-update golden files.

pub fn assert_tree_snapshot(
  tree: node.Node,
  name: String,
  path: String,

If no golden file exists, creates one (first run). If PLUSHIE_UPDATE_SNAPSHOTS=1 is set, updates the golden file. Otherwise compares JSON and panics on mismatch.

pub fn node_to_json(tree: node.Node) -> json.Json

Serialize a Node to deterministic JSON (sorted keys).
