Testing at leiningen

Question

I am writing a small Clojure project using leiningen with the following directory structure:

project
+ src
  + org/example/project/core.clj
+ test
  + org/example/project/core.clj

When I run lein test, it reports that it performed 0 tests with errors 0, but I specifically put a test that failed in the file test /.../ core.clj.

I added a line :test-path testto my file project.clj, and when I started again, I got an error:

I am running Clojure 1.2 and the last lane (1.3.1).

Looks like a problem with clojure.core or lein code.
