This property is a function and not a getter. Without invoking it as a function, it's value is always truthy.
When the process was terminated, all of the signal handlers were triggered causing multiple logs to be outputted. Skipping stopping the agent once another event has stopped it causes subsequent events to skip straight to exiting, and never finalizes builds. Exiting is tracked so that if it is already being handled, there is no need to handle exiting again.
The previous test tested that PERCY_ENABLED _did not_ work. That is, it tested that a warning was still thrown even though it was disabled. That test has been corrected to assert that _nothing_ is thrown when disabled.

Purpose
When running
percy execwith a command that causes the process to hang, terminating the process causes builds to get stuck in a receiving state due to the build never finalizing.Approach
Add signal handlers for
SIGHUP,SIGINT, andSIGTERMto stop and finalize the build.Multiple signals are sometimes sent and cause the stop method to get called multiple times. This didn't seem to effect finalizing builds, but caused noisy output in the terminal. An instance property,
exiting, is used to bail out of the stop method when it has already been called. This also prevents secondary events from exiting before the first event has finalized the build.Other changes
I also corrected a check for
percyEnabledwhich treated the property as a getter when it is actually a method. Fixing this also highlighted a test which actually tested the incorrect behavior. This test was updated to reflect the desired behavior, which is to not warn about a missing token when Percy is disabled.
