This PR makes the charge function fallible, so that when the the caller is unable to pay for the storage deposit we rollback the whole transaction.

would be nice to test that the transaction gas were actually charge to the user, but I am not too sure how this can be done within our test framework

can't you just check that Alice's balance became lower than it was before the tx?

Updated the test, so we can validate that the fees are the same whether the transaction fails (because the payment failed) or not.
I don't think we can test Alice's balance because as far as I know, this would be done in the pre/post hook of the transaction_payment pallet that does not exist in the Test config

for reference

fn pre_dispatch(
self,
who: &Self::AccountId,
call: &Self::Call,
info: &DispatchInfoOf<Self::Call>,
len: usize,
) -> Result<Self::Pre, TransactionValidityError> {
let (_fee, imbalance) = self.withdraw_fee(who, call, info, len)?;
Ok((self.0, who.clone(), imbalance))
}
fn post_dispatch(
maybe_pre: Option<Self::Pre>,
info: &DispatchInfoOf<Self::Call>,
post_info: &PostDispatchInfoOf<Self::Call>,
len: usize,
_result: &DispatchResult,
) -> Result<(), TransactionValidityError> {
if let Some((tip, who, imbalance)) = maybe_pre {
let actual_fee = Pallet::<T>::compute_actual_fee(len as u32, info, post_info, tip);
T::OnChargeTransaction::correct_and_deposit_fee(
&who, info, post_info, actual_fee, tip, imbalance,
)?;
Pallet::<T>::deposit_event(Event::<T>::TransactionFeePaid { who, actual_fee, tip });
}
Ok(())
}

You can check the events emitted during execution. We do that in other tests. There is a event for transaction fee payment.

we would need the transaction_payment pallet for this in test, I don't think we have it 🤔 might have overlooked, will check again

Ahh yeah. You are right. We didn't set this up in tests. It is fine. We don't really need to test this.

docs above this line could be improved a bit to reflect the fact this is now a fallible fn
