Created February 10, 2016 12:02
Capture stderr in specs
# When you using rspec for commandline tools, and you want to capture stderr in a test,
# this method allows you to do it.
# It could also be adapted to stdout.
#
# Use like:
# stderr = capture_stderr do
# expect{ MyClass.new(arg1, arg2).to raise_error(SystemExit, "my abort message here")
# end
#
# Then you can make expectations based on the variable stderr
