Testing PUT requests with Culerity

Sun, 31 Jan 2010 21:22:00 +0000

One major pain at testing with culerity so far was a HtmlUnit bug that causes a ScriptException with PUT AJAX requests in jQuery. When you tried to test an update you got a “java.lang.IllegalArgumentException: The content cannot be null”. Fortunately, this bug is fixed now. With latest HtmlUnit build culerity should run fine, and I tell you how.

I assume you have culerity installed already. If not, follow these instructions for testing Rails apps or these for testing Couchapps.

1. Make sure you have up-to-date versions of celerity and culerity:
$ jruby -S gem install celerity #(gives you celerity-0.7.8)
$ gem install culerity –source http://gemcutter.org #(gives you culerity-0.2.7)

2. Get the latest HtmlUnit nightly build:
$ wget http://build.canoo.com/htmlunit/artifacts/htmlunit-2.7-SNAPSHOT-with-dependencies.zip
$ unzip htmlunit-2.7-SNAPSHOT-with-dependencies.zip
$ cd htmlunit-2.7-SNAPSHOT-with-dependencies/lib
These are the jar files you need to copy into your celerity gem.

3. Find your celerity gem and copy the files:
$ jruby -S gem which celerity
$ cp * PATH_OF_JRUBY_INSTALLATION/lib/ruby/gems/1.8/gems/celerity-0.7.7/lib/celerity/htmlunit

4. The new HtmlUnit needs JQuery 1.4, so you need to upgrade if you haven’t done already. There’s a backwards compatibility plugin for 1.3 if this gives you trouble.

Have fun!
