Run tests from Clojure Repl and Leiningen
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
.
├── doc
│ └── intro.md
├── LICENSE
├── project.clj
├── README.md
├── resources
├── src
│ └── first_project
│ └── core.clj
├── target

│ └── extract-native.dependencies
└── test
└── first_project
└── core_test.clj
Without modifying any files, I can lauch successfully the only failing test with
lein test
...
Ran 1 tests containing 1 assertions.
1 failures, 0 errors.
Tests failed.
But I am unable to do the same from the REPL using run-tests
lein repl
first-project.core=> (use 'clojure.test)
nil
first-project.core=> (run-tests)
Testing first-project.core
Ran 0 tests containing 0 assertions.
0 failures, 0 errors.
{:type :summary, :pass 0, :test 0, :error 0, :fail 0}
I tried (but does not work)
(require 'first-project.core-test)
Answer
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
