After the existing if statement, create another one to raise a ValueError when new_level is already the selected level.
For the message, use '{level}' is already the selected level., where {level} should be replaced by the current level.
You should have a second if statement inside your level setter.
({ test: () => assert(runPython(`_Node(_code).find_class("Employee").find_functions("level")[1].find_ifs()[1]`)) })
When new_level is equal to self.level, you should raise a ValueError with the message '{level}' is already the selected level., where {level} should be replaced by the current level.
({ test: () => runPython(`
emp = Employee('Frank', 'trainee')
try:
emp.level = "trainee"
except ValueError as e:
assert str(e) == "'trainee' is already the selected level."
else:
assert False, "Expected to raise ValueError with invalid new_level"
`) })
