How to Ask a Question

Be Kind, Polite and Respectful

Please remember that you’re asking for volunteers to help you on their own limited free time. Saying “hi” and “thank you” really warms their heart!

Use Up-to-Date Versions

Please make sure to use the latest version of Gatling, in particular if you think you’ve found a bug. This bug might have already been fixed. Gatling developers won’t have time to dig into old versions.

Provide a Reproducer

If you think you’ve found a bug, please provide a reproducer so Gatling developers can investigate. Otherwise, they won’t be able to search a needle in a haystack and figure out if the issue is really in Gatling or in your own system.
