* Humane test output for clojure.test
  This library does two things:
    1. Test output is pretty printed.
    2. Equality assertions are also diffed.

  To use this library, include it in your dev profile:
  : [pjstadig/humane-test-output "0.6.0"]
  
  To activate it you will need to call ~pjstadig.humane-test-output/activate!~.
  One way to do this would be to put this in a ~user.clj~ file in your test
  classpath.

  This test output formatting works great with Emacs and when running Leiningen
  in a console.  However, some IDEs are also bashing in their own versions of
  test formatting.  If you are on a mixed team and some members need to disable
  humane test output, they can define the ~INHUMANE_TEST_OUTPUT~ environment
  variable.

  Once humane-test-output is activated, instead of this:
  : FAIL in (a-test) (humane_test_output_test.clj:7)
  : FIXME, I fail.
  : expected: (= {:foo :bar, :baz :quux, :something "a long string?", :another-key "and another value"} {:fo :bar, :baz :quux, :something "a long string?", :another-key "and another value"})
  :   actual: (not (= {:another-key "and another value", :foo :bar, :something "a long string?", :baz :quux} {:another-key "and another value", :something "a long string?", :fo :bar, :baz :quux}))
  : 
  : FAIL in (a-test) (humane_test_output_test.clj:11)
  : FIXME, I fail.
  : expected: (= {:foo :bar, :baz :quux} {:foo :bar, :baz :quux} {:fo :bar, :baz :quux})
  :   actual: (not (= {:foo :bar, :baz :quux} {:foo :bar, :baz :quux} {:fo :bar, :baz :quux}))
  : 
  : FAIL in (a-test) (humane_test_output_test.clj:14)
  : FIXME, I fail.
  : expected: (list? foo)
  :   actual: (not (list? {:another-key "and another value", :foo :bar, :something "a long string?", :baz :quux}))

  You get this:
  : FAIL in (a-test) (humane_test_output_test.clj:7)
  : FIXME, I fail.
  : expected: {:another-key "and another value",
  :            :foo :bar,

  :   actual: {:fo :bar}
  :     diff: - {:baz :quux,
  :              :something "a long string?",
  :              :foo :bar,
  :              :another-key "and another value"}
  :           + {:fo :bar}
