===== BISECT JOB RESULTS ===== Status: completed ===== SUSPECTED CL(s) ===== Subject : [system-health] Run all SH stories in memory benchmarks Author : petrcermak Commit description: This patch modifies SH memory benchmarks (system_health.memory_desktop and system_health.memory_mobile) to run all SH stories: - load:* (already running) - browse:* (NEW) As a result, all SH stories will also run in the SH smoke test on the Chromium CQ (benchmarks.system_health_smoke_test.SystemHealthBenchmarkSmokeTest.*). *** NOTE TO SHERIFF *** This patch is very likely to cause failures in the System Health benchmarks (perf waterfall) and smoke tests (regular CQ). Please contact me before reverting.
