Robot Framework Telnet Connection retry

Question

Sometimes I got

> error: [Errno 111] Connection refused

and then all my test fail. Looking for a way to force the telnet to retry few times.

This is how my connection command looks like:

> Telnet.Open Connection ${IP} \ \ \ \r None

Answer 1

You can use Wait Until Keyword Succeeds. For example, you could have it try every 15 seconds for two minutes like this:

Example
    Wait until keyword succeeds    2 minutes    15 seconds
    \ Telnet.Open Connection ${IP} \ \ \ \r None
