Howto automate tests w/ ClojusreScript?

[Timothy Washington]

Hey all, 

I'm digging into ClojureScript at the moment, and am trying to figure out how to automate generated JS code in a shell, like v8. 

In ClojureScript, I have been able to to pull in Google Closure's "goog.testing.jsunit" package. Next step is to take the generated JS code (optimized or not), and be able to automate tests in a JS shell, like v8, SpiderMonkey, rhino, etc. This is where I run into problems. In the directory in which I ran "cljs", I run v8, then load "out/goog/base.js" (analogous to what you'd do in a browser). "bkeeping.js" is generated from "bkeeping.cljs". goog.require breaks at first, until I try it with fubar'd namespace. Then I retry goog.require, and it works. However, I don't see the results of the unit test run. 

Any ideas of what I'm missing?

Thanks for any help 

Tim

Sorry, I should have been clearer. 

In a JS shell (v8, for example), after running... load('bkeeping.js'); , I expect to have a bkeeping object. But that's not there. So I tried a goog.require('bkeeping.js'); , and a 'bkeeping' object still wasn't there. 

Basically, I'd like to able to run compiled JS code in a JS shell. But I'm coming up short (with and without compiler optimizations) in v8, rhino and SpiderMonkey. 

Any ideas?

This should be:

load('out/goog/base.js');
load('out/goog/deps.js');
load('bkeeping.js');

Hmm, I tried this with a v8 shell, and I still get...

> load('out/goog/base.js');

> load('out/goog/deps.js');

> load('bkeeping.js');

> bkeeping.fubar("thing");

(shell):1: ReferenceError: bkeeping is not defined

bkeeping.fubar("thing");

^

Where "cat bkeeping.cljs" gives...

(ns bkeeping

  (:require [goog.testing.jsunit :as testing]))

  

(defn ^:export fubar [n] 

  (str "ZZzz: " n)

)
