Overview

assert-file Example1:

es = AssertFile.new("testdata/shorten-test.e")
el = AssertFile.new("testdata/shorten-test.el")
system "shorten.rb -l #{el} -e #{es}  testdata/shorten-test-input.e"
assert_file(es)
assert_file(el)

Example2:

assert_file(:expected=>expected, :actual=>actual, :no_remove=>true)

Example3:

AssertFile.transaction(expected) {|asf|
  system "foo input > #{asf}"
}
