Hey, Ruby coders!
Do you recognize this idiom?
Or this one?
When I wanted to do these two things in my RubyTest project, I had to Google to find out how.
Now if I put this code into my project, will I recognize these idioms later on? Next month? Next year?
I could add comments to explain, but a comment can get stale (not keep up with code changes), or get separated from its code, or even get deleted.
You can help your downstream code enhancer/maintainer by pushing an unusual idiom into a well-named method.
(Hint: If you're not sure who is the downstream enhancer/maintainer, it's you!)
Thus, I created this:
class ObjectHelper def self.get_class_for_class_name(class_name) Object::const_get(class_name) end def self.instantiate_class_for_class_name(class_name, *args) self.get_class_for_class_name(class_name).new(*args) end end
PS: My GitHub project is about test automation in Ruby. It has a Tester Tour of the demo testing for a web UI and for a REST API.
