Andes Checklist is a tool used by software testers to help identify bugs and other issues in the software they are testing. It was developed in the early 1990s by software engineer Andes Jarlsberg. The checklist consists of a series of questions that testers can use to evaluate the functionality of a system. The questions cover a wide range of topics, such as input validation, user interface design, database performance, exception handling, and security. There are two types of Andes Checklist: the Standard Checklist and the Advanced Checklist. The Standard Checklist is intended for testers who are new to the field, and the Advanced Checklist is designed for experienced testers. Both checklists include questions related to the same topics, but the Advanced Checklist includes additional questions that are more complex.
