How to get access to pallet storage from tests

Question

I have approvals map in my pallet

So when i try to get value from my storage, I'm getting this error

So how to properly use pallet storage in tests?

Answer 1

You could add a getter for your storage.

#[pallet::storage]
#[pallet::getter(fn approvals)]
pub type Approvals<T: Config> = StorageDoubleMap<...>;

Then it could be used in your test.

assert_eq!(TemplateModule::approvals(whitelisted_caller(), recipient), Some(true));
