Elixir's assert_diff

Simple Elixir's assert_diff for strings which fallbacks to git diff.

It works ONLY within git repo.

Installation

1. Add assert_diff to your list of dependencies in mix.exs:

   def deps do [{:assert_diff, "~> 0.0.2"}] end

2. Import it to your test case:

   import AssertDiff

3. Make sure that you have tmp directory: your_app/tmp

4. Use it:

   test "some test goes here" do assert_diff "Cat" == "Dog" end
