guess_constructor(arg) click to toggle source

Don’t recognise the type so we don’t know how to recreate it in source code. So we’ll take a guess at what might work and let the user fix it up if necessary.

# File lib/mkspec/expectation.rb, line 73
def guess_constructor(arg)
  "#{arg.class.name}.new(#{serialise(arg.to_s)})"
end

end

serialise(arg) click to toggle source

Attempt to recreate the source-code to represent this argument in the setup for our generated spec.

# File lib/mkspec/expectation.rb, line 62
def serialise(arg)
  if %w(Array Hash Float Fixnum String).include? arg.class.name
    arg.pretty_inspect.chop
  else
    guess_constructor arg
  end
