This last week I've been getting to know <a href="http://chneukirchen.org/blog/archive/2007/01/announcing-test-spec-0-3-a-bdd-interface-for-test-unit.html">test/spec</a> via <a href="http://errtheblog.com/">err's</a> <a href="http://require.errtheblog.com/plugins/wiki/TestSpecRails">test/spec on rails</a> plugin. I have to say that I really dig this method of testing my code and I look forward to trying out some actual <a href="http://behaviour-driven.org/">BDD</a> in the future.

I did hit a little snag with functional testing though. The method of declaring which controller to use takes the form:
|
|
|
|
```ruby
|
|
use_controller :foo
|
|
```
|
|
|
|
and can be placed in the <code>setup</code> method, like so:
|
|
|
|
```ruby
|
|
# in test/functional/sessions_controller_test.rb
|
|
|
|
context "A guest" do
|
|
fixtures :users
|
|
|
|
setup do
|
|
use_controller :sessions
|
|
end
|
|
|
|
specify "can login" do
|
|
post :create, :username => 'sjs', :password => 'blah'
|
|
response.should.redirect_to user_url(users(:sjs))
|
|
...
|
|
end
|
|
end
|
|
```
|
|
|
|
This is great and the test will work. But let's say that I have another controller that guests can access:
|
|
|
|
```ruby
|
|
# in test/functional/foo_controller_test.rb
|
|
|
|
context "A guest" do
|
|
setup do
|
|
use_controller :foo
|
|
end
|
|
|
|
specify "can do foo stuff" do
|
|
get :fooriffic
|
|
status.should.be :success
|
|
...
|
|
end
|
|
end
|
|
```
|
|
|
|
This test will pass on its own as well, which is what really tripped me up. When I ran my tests individually as I wrote them, they passed. When I ran <code>rake test:functionals</code> this morning and saw over a dozen failures and errors I was pretty alarmed. Then I looked at the errors and was thoroughly confused. Of course the action <strong>fooriffic</strong> can't be found in <strong>SessionsController</strong>, it lives in <strong>FooController</strong> and that's the controller I said to use! What gives?!

The problem is that test/spec only creates one context with a specific name, and re-uses that context on subsequent tests using the same context name. The various <code>setup</code> methods are all added to a list and each one is executed, not just the one in the same <code>context</code> block as the specs. I can see how that's useful, but for me right now it's just a hinderance as I'd have to uniquely name each context. "Another guest" just looks strange in a file by itself, and I want my tests to work with my brain not against it.
|
|
|
|
My solution was to just create a new context each time and re-use nothing. Only 2 lines in test/spec need to be changed to achieve this, but I'm not sure if what I'm doing is a bad idea. My tests pass and right now that's basically all I care about though.
