Expected behavior

The tests should fail if there are no agents.
This is happening for:

agents-text
agents-tagged
agents-untagged
agents-stress

agents-dms properly fails if no agents are deployed

Steps to reproduce the bug

Run any of these agent tests against any D14N environment:

agents-text
agents-tagged
agents-untagged
agents-stress
