clojure, twitter and test-is

Here’s a way, using clojure, to get your tests alerts on twitter.

Go get 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.")))

Just 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 actually) running every week, and letting me know if all is good.

This little twitter-update is very easy to use for any kind of alerts and automations.
