0.1.0 - 2026-08-18

Initial release.

  • Elixir trace-point macros (tp/2, tp/3, tp_span/3, tp_span/4) wrapping snabbkaffe's Erlang preprocessor macros, with production behaviour controlled by :level and ignore_side_effects:.
  • check_trace/2,3 running and collecting a trace, with checks that pass unless they raise so ordinary ExUnit assertions work.
  • Trace-querying helpers (of_kind/2, projection/2, find_pairs/3, causality/3,4, strict_causality/3,4, and friends), all taking the trace first so they pipe.
  • Waiting helpers (block_until/2,3,4, wait_async_action/3, subscribe, receive_events/1, retry/3).
  • Fault injection and scheduling via snabbkaffe_nemesis (inject_crash, fix_crash, force_ordering).
  • Multi-node trace forwarding (forward_trace/1, unforward_trace/1).
