How to read json input in stdin ?

Tue, 17 Sep 2019 12:49:04 +0000

I need to read json line input in stdin

Example INPUT

{ "foo" : "bar" }

Testing the -main function who reads from in

Tue, 27 Aug 2019 12:45:38 +0000

My -main function reads arguments from *in*, like this:

(defn -main
  [& args]
  (doseq [ln (line-seq (java.io.BufferedReader. *in*))]
  ; Do something...
))

I use my app basically like: $ lein run < input.txt.

I would like to test this function but I don't know how I would write a test case that simulates the stdin passing data to my -main function.

Thank you.
