Baseline rules catch configuration that should never reach production. This page has one rule so far. More will be added as the rConfig test suite covers them.
Interfaces created for lab work or temporary testing tend to outlive the test. They carry addresses nobody monitors and often sit outside the normal ACL and description standards. This rule fails if any line contains interface followed later on the same line by test. The match is case-sensitive, so the rule only works if your naming standard uses lowercase test.
