Class: FastCov::FileTracker

Inherits:
AbstractTracker show all
Defined in:
lib/fast_cov/trackers/file_tracker.rb

Overview

Tracks files read from disk during coverage (JSON, YAML, .rb templates, etc.) via File.read, File.open, and YAML load methods.

YAML methods are patched separately because Bootsnap’s compile cache overrides YAML.load_file/safe_load_file to bypass File.open entirely.

Register via: coverage_map.use(FastCov::FileTracker)

Defined Under Namespace

Modules: FilePatch, YamlPatch
