According to the previous requirements, we need to create the following new test function in the 60100 codeunit:

procedure AssignBlockedCustomerCategoryToCustomer()
// [FEATURE] Customer Category
begin
    // [SCENARIO #0002] Assign blocked customer category to
    //                  customer
    // [GIVEN] A blocked customer category
    // [GIVEN] A customer
    // [WHEN] Set customer category on customer
    // [THEN] Blocked category error thrown
end;
