Need Model Unit Testing

[Mohankumar k.o]

Hi all
I need Model side unit testing for the code below,

Please help me to get it done.

def terminal_access

unless terminal_access_key.present?

$redis.set("#{self.user_name}_terminal_access_cache_key",

{result: (mlodge_terminals + ltv_terminals + tv2g_terminals).flatten.as_json(only: [:app_cd, :gw_tid])}.to_json)

end

JSON(terminal_access_key)['result']

end
