it's asked that the function allowance(address,uint) takes an address and uint, is It correct?
Hi @MalekLahbib, the instructions for this exercise can be improved. Besides the required functions, the contract needs to have two public states: accounts
and allowance
. I imagine your solution doesn't have accounts
state or the state is defined but it's not public
I will open a PR to clarify the subject.

It's talking about an accounts function, but no one asked to create such a function, are the instructions and the test correspondent?
