Testing in leiningen
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 ran 0 tests with 0 failures, but I purposely put a test designed to fail in the test/.../core.clj file.
I added the line :test-path test
to my project.clj
file and when I re-ran, got the error:

I am running Clojure 1.2 and the latest lein (1.3.1).
Looks like a prob开发者_开发百科lem with either clojure.core or the lein code.
Had the same issue. After a while I noticed that leins default path to tests are:
test/{project-name}/test/{file-under-test}.clj
^^^^
Note an extra test
directory in the path.
As for the source layout. I think you basically shadow your test with the real core.clj file. That's probably why clojure.test
doesn't find any tests. Did you try a different namespace and file name? eg. test/example/project/test_core.clj
.
