The following revision refers to this bug: https://chromium.googlesource.com/chromiumos/third_party/autotest/+/2c06c1e0c2e2450c335e30f1f6fe2474936f3759 commit 2c06c1e0c2e2450c335e30f1f6fe2474936f3759 Author: Brian Norris <briannorris@chromium.org> Date: Sun Dec 02 05:19:16 2018 [autotest] network_WiFi_ChannelScanDwellTime: correct list checks CL:1097984 incorrectly refactored our list-collation logic. Today, it's not possible to hit the 'Failed to find any BSS' code, since the only TimeoutError is when _bss_list is None (which is different than []). Instead, we get this, when the empty list makes its way into logic that didn't expect it: File "/usr/local/autotest/server/site_tests/network_WiFi_ChannelScanDwellTime/network_WiFi_ChannelScanDwellTime.py", line 82, in _get_dwell_time index_diff = ssid_index[-1] - ssid_index[0] IndexError: list index out of range I picked a semi-related BUG=, because we're not seeing that symptom any more, and are instead seeing this Error. We still should probably figure out why we fail the test.
