Automated Linters on F5

whisperer has the right advice here where traffic policies can be implemented in lieu of iRules. iRules are great, but should be used only where necessary. For static analysis, I'm not sure there are tools for that for iRules because it's a heavily extended/customized version of Tcl 8.4.6. I'm checking with someone who might have a more definitive answer, will update here when I hear back.

That said, if you have the ability to upload qkviews of BIG-IP systems configs (even if just a dummy config for the purposed of testing), you could use the ihealth API to check for any iRules-related diagnostics/heuristics that might trigger against your configurations.

On the flip side, if you're look for iRules unit testing, you can check out the questionably named TestTcl, um, package.
