Defined in:
lib/cov_loupe/loaders/resultset_loader.rb

Overview

Reads and parses a SimpleCov .resultset.json file.

Handles both single-suite and multi-suite resultsets. For multi-suite files, it delegates to SimpleCov's ResultsCombiner (requiring the simplecov gem). Legacy resultsets that store raw line arrays (instead of { "lines" => [...] } hashes) are normalized to the newer format.

Timestamps are extracted from the "timestamp" or "created_at" fields and normalized to integer epoch seconds. Missing or unparseable timestamps default to 0, which disables time-based staleness checks.
