Overview

TestMappingExtractor maps test files to the units they exercise.

Scans spec/*/_spec.rb (RSpec) and test/*/_test.rb (Minitest) to produce one ExtractedUnit per test file. Extracts subject class, test count, shared example usage, and test framework type.

Units are linked to the code under test via :test_coverage dependencies, inferred from the subject class name and file directory structure.

Examples:

extractor = TestMappingExtractor.new
units = extractor.extract_all
spec = units.find { |u| u.identifier == "spec/models/user_spec.rb" }
spec.metadata[:subject_class]  # => "User"
spec.metadata[:test_count]     # => 12
