As a newbie to clojure, I have used leiningen to create a sample project with
lein new app first-project
which gave me this directory
Start a REPL with lein repl
, then use require
(require '[clojure.test :refer [run-tests]])
(require 'your-ns.example-test :reload-all)
(run-tests 'your-ns.example-test)
I prefer to stay in the user
namespace, as opposed to changing it with in-ns
as mentioned by another answer. Instead, pass the namespace as an argument to run-tests
(as shown above).
I'd also recommend staying away from (use 'clojure.test)
; that is why I suggested (require '[clojure.test :refer [run-tests]])
above. For more background, read http://dev.clojure.org/jira/browse/CLJ-879
To recap:
Way of require
Full qualification of functions is only needed if you issued an in-ns
earlier. Then do:
(clojure.core/require '[clojure.core :refer [require]]
'[clojure.test :refer [run-tests]]
'[clojure.repl :refer [dir]])
; Load whatever is in namespace "foo.bar-test" and reload everything
; if `:reload-all` has been additionally given
(require 'foo.bar-test :reload-all)
;=> nil
; List your tests for good measure (Note: don't quote the namespace symbol!)
(dir foo.bar-test)
;=> t-math
;=> t-arith
;=> t-exponential
;=> nil
; Check meta-information on a test to verify selector for example
(meta #'foo.bar-test/t-math)
;=> {:basic-math true, :test #object[foo.bar_tes...
; `run-tests` will probably run nothing because the current namespace
; doesn't contain any tests, unless you have changed it with "in-ns"
(run-tests)
;=> Ran 0 tests containing 0 assertions.
; run tests by giving namespace explicitly instead
(run-tests 'foo.bar-test)
;=> Ran 3 tests containing 29 assertions.
In your example above the repl is in the wrong namespace. It may work better if you switch the repl to the core_test
namespace. and then run (run-tests)
.
(in-ns 'first-project.core-test)
(run-tests)
Another fun way of developing tests is to just run them from the REPL until they work, because tests are normal functions with some extra metadata.
(in-ns 'first-project.core-test)
(my-test)
Remember you have to load the file in addition to calling in-ns
Let's say your test file is tests/first_project/core_test.clj
, then you will need to call
(load "tests/first_project/core_test")
(in-ns 'first-project.core-test)
(my-test)
Keep in mind that _
in the file system becomes -
in the namespace and /
becomes .
