Check that all public or external functions are override. This is iseful to make sure that the whole API is extracted in an interface.

Bad Practice

1. A public function is not an override

pragma solidity ^0.7.0;

contract Foo {
  function foo() public {}
}

Recommended

1. All public functions are overrides

pragma solidity ^0.7.0;

contract Foo is FooInterface {
  function foo() public override {}
}
