Overview

Lists the branches a method still needs covered and renders ready-to-paste ‘context ’…‘ do # rspec_parity:covers <branch>` stubs. Backs the `rspec-parity-cover` executable, reusing SufficientContexts’ branch analysis.

When the spec file exists, only branches without a covering annotation are listed (and only for methods that aren’t already fully covered). When it is missing, every branch is listed so a new spec can be bootstrapped.

Constructor Details

#initialize(source_path, spec_path: nil, line: nil) ⇒ CoverageReporter

line narrows the report to the single method enclosing that source line, so ‘rspec-parity-cover file.rb:20` targets one method.
