Module: RSpec::Signal::Backtrace::Parser

Defined in:
lib/rspec/signal/backtrace/parser.rb

Overview

Turns raw backtrace strings into Frames.

Handles the two shapes Ruby emits:

"/path/to/file.rb:12:in `method'"
"/path/to/file.rb:12:in 'Klass#method'"   (Ruby 3.4+ quoting)

and the shapes RSpec emits after its own filtering:

"./spec/models/user_spec.rb:12"
