Why does is_valid_html? work without internet connection, and is_valid_css? doesn't?

It seems that is_valid_css? has to connect to the internet to work, while is_valid_html? doesn't. At least on my machine it's like this.

What's the explanation? Does is_valid_html? connect to some local utility? Maybe tidy? I can't remember that I ever installed the validator.nu service locally...?!

Thanks for explanation, Josh.

There's no local tool fallback, but the gem does cache responses so it's possible your tests ran once hitting the net and then each test run after that has used the on-disk cached response.

Try disabling caching and seeing if the tests start hitting the internet again.

BeValidAsset::Configuration.enable_caching = false

I don't know why the css validator is definitely hitting the network though as it should also be cached. Are you using cachebusting on the css file urls and thus between test runs the url for the css files is not static so it doesn't hit the cache?

Hey, thank you for your answer. Disabling the cache indead results in 2 errors.

How do I check whether I am using cachebusting?
