I have a method which compares if two text files have the same content.
How do I compare if two text files have the same content using RSpec?
On a trivial level:
IO.read(file1).should == IO.read(file2)
If you want to do something nicer, you're likely going to need to write a new matcher, something like have_same_content_as
defined to check for the above condition. "Up and Running with Custom RSpec Matchers" is a nice tutorial on writing custom matchers.
