test_equality_with_lcs

Compare two strings, or arrays, and get failed results back in an easy to distinguish LCS output.

Let’s say you want to test two strings: @string1 = “Hello World!” @string2 = “Hello Bob!”

*Unit tests*: class ClassName < Test::Unit::TestCase

include TestEqualityWithLCS::Unit

def test_something

assert_equal_with_lcs @string1, @string2

end

end

and

*Spec tests*: define “Something” do

include TestEqualityWithLCS::Spec

it "matches" do
  @string1.should be_equal_with_lcs(@string2)
end

end

result in the output:

‘ ! ! ’ ‘Hello World!’ ‘Hello Bob !’

  • without the quotes though. I added them to bring attention to the included whitespace.

    bump version in a commit by itself I can ignore when I pull)
