The 'right' way to run unit tests in Clojure

Question

Currently, I define the following function in the REPL at the start of a coding session:

(defn rt []
  (let [tns 'my.namespace-test]
    (use tns :reload-all)
    (cojure.test/test-ns tns)))

And everytime I make a change I rerun the tests:

user=>(rt)

That been working moderately well for me. When I remove a test, I have to restart the REPL and redefine the method which is a little annoying. Also I've heard bad rumblings about using the use function like this. So my questions are:

• Is using use this way going to cause me a problem down the line?
• Is there a more idiomatic workflow than what I'm currently doing?

Answer 1

most people run

lein test

form a different terminal. Which guarantees that what is in the files is what is tested not what is in your memory. Using reload-all can lead to false passes if you have changed a function name and are still calling the old name somewhere.

• calling use like that is not a problem in it's self, it just constrains you to not have any name conflicts if you use more namespaces in your tests. So long as you have one, it's ok.
• using lein lets you specify unit and integration tests and easily run them in groups using the test-selectors feature.
