I do something like the following in my models:

class NoDeleteCompanyError \< RuntimeError; end

class Company \< ActiveRecord::Base  
# model code  
end

When I try to do:

assert\_rais(NoDeleteCompanyError) { some\_block }

It says that NoDeleteCompanyError is an uninitialized constant.

To fix this I just do fixtures :companies.

Is there anyway to default load all models when testing so I dont have  
to do this?

Thanks.

Probably 😉 But another way would be to put your NoDeleteCompanyError  
into no\_delete\_company\_error.rb in your models directory…

Or it will probably work if you put the exception class inside your  
model

class Model  
class MyException \< RuntimeError; end  
end

Also, check out the all\_fixtures pluign I wrote:  
[http://beautifulpixel.com/all\_fixtures/index.html](http://beautifulpixel.com/all_fixtures/index.html)

It makes fixture management quite painless.

Try it inside the class, and use Company::NoDeleteCompanyError to  
identify the Exception class.

assert\_raise(Company::NoDeleteCompanyError) do  
some\_block  
end

The problem I have with that is that I cant catch that specific class  
outside of that model because it gives me an unititalized constant  
error. That’s why I put it outside the class.
