After your existing if statement, create another one for when the new salary is less than the base salary for the current level.
Inside the if statement, raise a ValueError with the message Salary must be higher than minimum salary $ followed by the base salary for the current level and a period.
You should have a second if statement in your salary setter.
({ test: () => assert(runPython(`_Node(_code).find_class("Employee").find_functions("salary")[1].find_ifs()[1]`)) })
When the new salary is less than the base salary for the current level, you should raise a ValueError with the message Salary must be higher than minimum salary $ followed by the base salary for the current level and a period.
({ test: () => runPython(`
emp = Employee('Frank', 'trainee')
built_in_print = print
print = lambda x: x
minimum_salary = Employee._base_salaries['trainee']
try:
emp.salary = minimum_salary - 1
except ValueError as e:
print = built_in_print
assert str(e) == f"Salary must be higher than minimum salary \${minimum_salary}."
else:
assert False, "Expected to raise ValueError with invalid new_salary"
`) })
You should not raise any exception when new_salary is greater than the current salary.
