From e78dace8dcb23c371df19c9add65895adf436995 Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Sat, 21 Jul 2018 03:31:51 +0200 Subject: [PATCH] bpo-33723: Fix test_time.test_process_time() (GH-8358) The test failed on my laptop because the busy loop took 15.9 ms whereas the test expects at least 20 ms. Modify test_process_time() as test_thread_time() has been modified recently: only require 15 ms instead of 20 ms. --- Lib/test/test_time.py | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-) diff --git a/Lib/test/test_time.py b/Lib/test/test_time.py index 1ebe0cf568..cab437d44a 100644 --- a/Lib/test/test_time.py +++ b/Lib/test/test_time.py @@ -496,18 +496,23 @@ class TimeTestCase(unittest.TestCase): # on Windows self.assertLess(stop - start, 0.020) + # bpo-33723: A busy loop of 100 ms should increase process_time() + # by at least 15 ms + min_time = 0.015 + busy_time = 0.100 + # process_time() should include CPU time spent in any thread start = time.process_time() - busy_wait(0.100) + busy_wait(busy_time) stop = time.process_time() - self.assertGreaterEqual(stop - start, 0.020) # machine busy? + self.assertGreaterEqual(stop - start, min_time) - t = threading.Thread(target=busy_wait, args=(0.100,)) + t = threading.Thread(target=busy_wait, args=(busy_time,)) start = time.process_time() t.start() t.join() stop = time.process_time() - self.assertGreaterEqual(stop - start, 0.020) # machine busy? + self.assertGreaterEqual(stop - start, min_time) info = time.get_clock_info('process_time') self.assertTrue(info.monotonic) -- 2.49.0
