[Autotest failure] network_WiFi_BSSTMReq has over 40% failure rate |
||||
Issue descriptionNewly added network_WiFi_BSSTMReq test has very high failure rate. See link below. Most failures are due to "Failed to roam" error while few others are due to "Autotest client terminated unexpectedly: DUT is pingable, SSHable and did NOT restart un-expectedly. We probably lost connectivity during the test., client.bin.job.__init__ failed: [Errno 28] No space left on device" https://stainless.corp.google.com/search?view=matrix&row=queued_date&col=test&first_date=2018-05-05&last_date=2018-05-18&test=%5Enetwork%5C_WiFi%5C_BSSTMReq%24&exclude_cts=true&exclude_not_run=true&exclude_non_release=true&exclude_au=true&exclude_acts=true&exclude_retried=true&exclude_non_production=false Sample log link https://pantheon.corp.google.com/storage/browser/chromeos-autotest-results/200920132-chromeos-test/chromeos15-row1-rack6-host1/network_WiFi_BSSTMReq/debug/

To fix (a), I checked for the output of the request ('OK' indicates that it is supported and was successfully sent) and raised a TestNAError if 'OK' was not found. To fix (b), I switched the two APs so that the client would instead be roaming from 2.4GHz band to 5GHz band. BUG= chromium:844762 TEST=Ran on machines that failed these tests (e.g. chromeos2-row11-rack4-host2 and chromeos2-row11-rack7-host6) and they now pass.
