Clojure test-is results in twitter

Here’s how you can have your your test-is results posted on twitter automatically as they run.

This is useful for example if you have regression tests that run automatically in a remote machine, once a week(for example) and want to find a good way to see the results.

Start by getting jtwitter, put it in your classphath and create:

(import 'winterwell.jtwitter.Twitter)

(defn twitter-update [the_message]
  (let [twitter (new Twitter "username" "password")]
    (.updateStatus twitter the_message)))

Update “username” and “password” with your twitter login.

Then hook it up to the /test-is’/library(test library in clojure): just overwrite the report summary method that by default prints out the summary of the executed tests.

Before:

(defmethod report :summary [m]
  (with-test-out
    (println "\nRan" (:test m) "tests containing"
    (+ (:pass m) (:fail m) (:error m)) "assertions.")
    (println (:fail m) "failures," (:error m) "errors.")))

After:

(defmethod report :summary [m]
  (with-test-out
    (twitter-update (str "[coverager] " (:fail m) " failures, " (:error m) " errors."))
    (println "\nRan" (:test m) "tests containing"
    (+ (:pass m) (:fail m) (:error m)) "assertions.")
    (println (:fail m) "failures," (:error m) "errors.")))

Note that i just added added a line calling the twitter-update method.

And thats it, now every time you run your tests, you will have the failures and errors twittered:

I’ve created a 2nd account on twitter where i post these automated messages. And have my clojure tests(regression tests) running by themselves and i just check twitter to see if all is good.

This little twitter-update method is very easy to re-use for other alerts and automations.
