+++ title = "Tests for nbd graph command" priority = 5 status = "done" ticket_type = "task" dependencies = ["9ad11f"] +++ Add comprehensive unit and integration tests for the nbd graph command introduced across tickets 9c9ebe, e14172, and 9ad11f.

Unit tests (src/tests.rs)

These test graph.rs and the rendering helpers in display.rs in isolation using in-memory Ticket values (no temp files needed).

graph.rs tests

test_graph_build_empty
  TicketGraph::build(&[]) has no nodes.

test_graph_roots_no_deps
  Two tickets with no dependencies → both appear in roots().

test_graph_roots_with_chain
  Ticket B depends on A → only A is a root.

test_graph_subtree_linear
  A → B → C; subtree("a") returns ["a", "b", "c"] (DFS order).

test_graph_subtree_single
  subtree of a leaf returns just that ID.

test_graph_subtree_cycle
  A.deps = [B], B.deps = [A] → subtree("a") returns both without panic/infinite loop.

test_graph_to_json_nodes_and_edges
  Three tickets with two edges → JSON "nodes" has 3 entries, "edges" has 2.

display.rs tests

test_format_graph_single_ticket
  One ticket, no deps → output contains the ID, status, and title on one line; no connector chars.

test_format_graph_two_ticket_chain
  A → B; output has A at col 0 and B indented with "└──".

test_format_graph_branching
  A has two dependents B and C; B's line uses "├──" and C's uses "└──".

test_format_subtree_scope
  A → B, C (unrelated root); format_subtree(graph, "a") does not contain C's ID.

test_format_graph_cycle_label
  Cycle present → output contains "[cycle]" and does not repeat infinitely.

Integration tests (tests/integration.rs)

Use a real temp directory set up with cargo run -- init and tickets created via cmd_create.

test_graph_empty_store
  `nbd graph` on an empty store produces an empty line (or at least exits 0).

test_graph_all_no_deps
  Create two tickets without deps; `nbd graph` output contains both IDs with no indentation.

test_graph_chain
  Create A (no deps) and B (--deps A); `nbd graph` output shows A at top level and B indented.

test_graph_single_ticket
  `nbd graph <id>` for A returns only A and its subtree, not unrelated tickets.

test_graph_json_output
  `nbd graph --json` parses as valid JSON with "nodes" and "edges" arrays.

test_graph_json_subtree
  `nbd graph <id> --json` returns JSON whose "nodes" array contains only reachable tickets.

test_graph_filter
  `nbd graph --filter type=bug` only shows bug tickets and their reachable deps.

test_graph_partial_id
  `nbd graph <3-char-prefix>` resolves to the correct ticket (prefix resolution).
