From beebe64419170eb9596c5375ba8efd13843542b1 Mon Sep 17 00:00:00 2001 From: normal Date: Sun, 28 May 2017 01:43:38 +0000 Subject: tests: increase CPU percentage threshold for assert_cpu_usage_low When sleeping for the tick rate of 100ms (defined in thread_pthread.c) as we do in test/ruby/test_io.rb (test_copy_stream_no_busy_wait), it may not be possible to measure with <= 10ms resolution on 100HZ systems (CONFIG_HZ in the Linux kernel). So increase the threshold to 15ms (10ms + 5ms slack for slow systems). * test/lib/test/unit/assertions.rb (assert_cpu_usage_low): increase pct default value [ruby-core:81427] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58934 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- test/lib/test/unit/assertions.rb | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'test') diff --git a/test/lib/test/unit/assertions.rb b/test/lib/test/unit/assertions.rb index 92f754064a..fcd9795402 100644 --- a/test/lib/test/unit/assertions.rb +++ b/test/lib/test/unit/assertions.rb @@ -715,7 +715,7 @@ eom skip end - def assert_cpu_usage_low(msg = nil, pct: 0.005) + def assert_cpu_usage_low(msg = nil, pct: 0.015) require 'benchmark' tms = Benchmark.measure(msg || '') { yield } max = pct * tms.real -- cgit v1.2.3
