Expect::Angel

I recently had the opportunity to try out Expect::Angel, a powerful Perl module designed to help establish a secure and reliable connection to your DUT. If you're looking for a solution that allows you to quickly build a robust connection, then Expect::Angel is an ideal choice.

The module operates as a messenger between your testing machine, which is essentially perfect, and the DUT or device under test, which may experience errors and disasters. The messenger, in this case, must be able to tolerate such issues while still effectively communicating information to and from the DUT. Expect::Angel is built on top of the Expect.pm module, but it hides most of its complexity so that you don't need to worry about the technical details.

Expect::Angel allows you to easily build an object-oriented module that meets your specific needs using the most valuable methods inherited from Angel. Additionally, the module has many useful features, making it an ideal choice for anyone looking to develop a reliable connection between their testing machine and DUT.

One example of how Expect::Angel could be used is with a CISCO router. In this case, Expect::Angel would be used to transition between various modes, such as non-privilege, enable, and config mode. The process may have many steps or states that must be followed to properly connect to the router, and Expect::Angel makes this process easy and streamlined.

In addition to the CISCO router example, Expect::Angel is also capable of simulating complex scenarios with a Linux machine. Overall, the module is an excellent choice for anyone looking to quickly create a reliable connection to their DUT.
