Examples:

returns method definition for attr_writer node

definitions = Rucoa::Source.new(
  content: "    class Foo\n      attr_writer :bar\n    end\n  RUBY\n  uri: '/path/to/foo.rb'\n).definitions\nexpect(definitions[1]).to be_a(Rucoa::Definitions::MethodDefinition)\n",

returns method definition for attr_accessor node

definitions = Rucoa::Source.new(
  content: "    class Foo\n      attr_accessor :bar\n    end\n  RUBY\n  uri: '/path/to/foo.rb'\n).definitions\nexpect(definitions.map(&:qualified_name)).to eq(\n  %w[\n    Foo\n    Foo#bar\n    Foo#bar=\n  ]\n)\n",

ignores unrecognizable attributes

definitions = Rucoa::Source.new(
  content: "    class Foo\n      attr_writer foo\n    end\n  RUBY\n  uri: '/path/to/foo.rb'\n).definitions\nexpect(definitions.map(&:qualified_name)).to eq(\n  %w[\n    Foo\n  ]\n)\n",
