Hello @imSanko, I want to help with this implementation, you are welcome to do any changes you want (as long as you don't implement MerchantAccountInterface for MockDb), and I can always merge with your changes.

Hello @SanchithHegde and @VedantKhairnar,

Looks like I will not be able to help with this implementation. My knowledge of Rust still not there.
I could only implement delete_merchant_account_by_merchant_id:

    async fn delete_merchant_account_by_merchant_id(
        &self,
        merchant_id: &str,
    ) -> CustomResult<bool, errors::StorageError> {
        let mut accounts = self.merchant_accounts.lock().await;
        let index = accounts
            .iter()
            .position(|account| account.merchant_id == merchant_id)
            .ok_or::<errors::StorageError>(errors::StorageError::ValueNotFound(format!(
                "No merchant account found for merchant_id = {merchant_id}"
            )))?;
        accounts.remove(index);
        Ok(true)
    }

Anyone is welcome to take over from now on.
