How do I compare if two text files have the same content using RSpec?

What does your current method look like? You say you have a method that does 'x' so please do show your code. – Sanborne

See sscce.org. You need to show code, sample data and any errors. – Arlon

Answer 1

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.

@Dom: I found it elsewhere and fixed the link. – Soap

Answer 2

For others who stumble across this, check the FileUtils#cmp method:

require 'fileutils'
expect(FileUtils.compare_file(file1, file2)).to be_truthy
