          self.name = name
          self.age = age
          self.email = email
      
      def toString(self):
          return f"Name: {self.name}, Age: {self.age}, Email: {self.email}"
  
  person = Person("John Doe", 30, "john.doe@example.com")
  assert person.toString() == "Name: John Doe, Age: 30, Email: john.doe@example.com"
  person2 = Person("Jane Smith", 25, "jane.smith@example.com")
  assert person2.toString() == "Name: Jane Smith, Age: 25, Email: jane.smith@example.com"
