testing: switch on all caching?

I would like to speed up my tests and I've noticed that not all caching is switched on in test.rb, and can't think why not.

I've thought to do this:

config.cache_classes = true config.action_controller.perform_caching = true config.action_view.cache_template_loading = true

Good idea?

Try it and find out. Think about what might go wrong: do you have tests expecting some behavior that caching might interfere with?

Also, I have some pretty big test suites, but they run in 1- 2 minutes at most. How long are yours taking? Is it perhaps inefficient code?

Thanks for the reply. It is that I can't think what would break. At the same time the project was configured by default with caching off, and yet a production site needs to have been tested with cacheing on. Therefore I would suppose there was a pretty good reason for that caching to be off that the rails devs know of, and I don't.
