It supports two flavours of assertion: + + * `assertMatchesSnapshot(lid, id)` — compare a workflow run against a baseline + snapshot file on disk. The file is created on first run; subsequent runs + compare against it. `UPDATE_SNAPSHOTS=true` refreshes the baseline. + * `assertEquivalent(lidA, lidB)` — compare two runs directly, no file. + +Snapshot file format and ignore semantics must stay aligned with the CLI: if a +test passes locally but `nextflow lineage validate` fails in CI (or vice versa) +the abstraction has leaked. +''')
