Class Method Details

.extract_file_path(example) ⇒ Object

Extracts file path from example, preferring id field over file_path This is important for shared examples where file_path points to the shared example file but id contains the actual spec file path (e.g., “./spec/features/entry_spec.rb”)

    example['file_path']
  end
end
