You can't use Symbols, but you can use Regexps

You can’t use Symbol (although Symbol is accepted with render :action => :new), like:

assert_template :new # WON'T WORK!

But you can use Regexp, e.g.:

assert_template /new/ # WORKS OK

Note that the String matched with your Regexp is the full path to the template relative to the view/ directory of your app, so this will not work:

assert_template /^new$/ # WON'T WORK!

However this might:

assert_template /^employees\/new.html.haml$/

As of v2.3.4 you can use Symbols

This commit fixes using a Symbol with assert_template

http://github.com/rails/rails/commit/f383a4aa333cd8a99003eb1bdbb27b6fdea1056c

assert_template :new # works in 2.3.4
