in application.rb

rescue\_from ActiveRecord::RecordNotFound { |e| http\_status\_code  
(:missing, e) }

def http\_status\_code(status, exception)  
@exception = exception  
respond\_to do |format|  
format.html { render :template =\> “shared/status\_#  
{status.to\_s}”, :status =\> status }  
format.any { head status }  
end  
end

in a controller

```
project = Project.find(params[:id])

```

in my test

def test\_bad\_project  
put :update, :id =\> KNOWN\_BAD\_ID  
assert\_response(:missing)  
end

The result is that I get a 500 every time.

Any clues as to whats’ going on? There’s nothing in the log to  
explain the 500 I get during tests; the application controller seems  
to be detecting the exception and setting the status to 404, but my  
tests get 500.

IIRC the test harness snarfs the exception before it gets to your  
exception handler.

The exception handler IS getting called (I put log statements in and  
they appear in test.log).

In previous versions of rails, there seemed to be some sort of magic  
where a non-200 http response gets turned into a 500 for development,  
but not production. Is that the case, and if so, how do I deal with  
this? I need to test that the correct http responses are being  
sent…
