beginners emacs / clojure compiling error

Question

I'm going through clojure & emacs tutorial from clojure-doc.org, and when compiling the test as suggested, i get following output in emacs nrepl:

    clojure.lang.Compiler$CompilerException: java.lang.RuntimeException: Unable to resolve symbol: deftest in this context, compiling:(/home/jakov/dev/PROJECTS/clojure/test2/test/test2/core_test.clj:1)

To me, it seems like this line is crucial in the nrepl error output:

Caused by: java.lang.RuntimeException: Unable to resolve symbol: deftest in this context

Anyway, i am really a clojure & emacs noob, and I dont have much clue here. All the emacs slime clojure stuff is installed, leiningen2 is installed, java is oracle java 1.6, emacs is emacs 24, and when I run lein test in projects directory, it goes without errors.

Can anyone help me?

EDIT:

My core_test.clj file:

    (deftest pairs-of-values
   (let [args ["--server" "localhost" 
               "--port" "8080" 
               "--environment" "production"]]
      (is (= {:server "localhost"
              :port "8080"
              :environment "production"}
             (parse-args args)))))

My core.clj file:

(defn parse-args [args]
  {})

You really should have posted the code that's in your file. Do you have (ns core-test2 (:use clojure.test)) in there? — Marko Topolnik
I was following clojure-doc.org tutorial word-for-word.. I edited my question, anyway — tonino.j
The tutorial says "Replace the test that is there with the following". I think you replaced the entire contents of the file, instead of only the (deftest ...) part. So the part that you deleted, but shouldn't have, said (ns command-line-arguments.core-test (:use clojure.test command-line-arguments.core)) — Marko Topolnik
Yup. I deleted everything there and put that. I'll try to put that back. — tonino.j
