[00258.289] 03969.04017> Tests took 251 seconds. When the test passes (e.g. https://ci.chromium.org/buildbot/chromium.fyi/Fuchsia%20%28dbg%29/15988), the reported timings from the relevant sub-process look like: [00203.252] 03939.04001> [2885/2894] MessageLoopTypedTest.RunLoopQuitOrderDuring/IO (12 ms) [00203.252] 03939.04001> [2886/2894] MessageLoopTypedTest.RunLoopQuitOrderDuring/UI (1 ms) [00203.252] 03939.04001> [2887/2894] MessageLoopTypedTest.RunLoopQuitOrderAfter/Default (9 ms) [00203.253] 03939.04001> [2888/2894] MessageLoopTypedTest.RunLoopQuitOrderAfter/IO (1 ms) [00203.253] 03939.04001> [2889/2894] MessageLoopTypedTest.RunLoopQuitOrderAfter/UI (1 ms) [00203.253] 03939.04001> [2890/2894] MessageLoopTypedTest.RecursivePosts/Default (1002 ms) [00203.254] 03939.04001> [2891/2894] MessageLoopTypedTest.RecursivePosts/IO (34515 ms) [00203.254] 03939.04001> [2892/2894] MessageLoopTypedTest.RecursivePosts/UI (9792 ms) [00203.255] 03939.04001> [2893/2894] MessageLoopTypedTest.NestableTasksAllowedAtTopLevel/Default (0 ms) [00203.255] 03939.04001> [2894/2894] MessageLoopTypedTest.NestableTasksAllowedAtTopLevel/IO (0 ms) ... [00258.289] 03969.04017> Tests took 251 seconds. This suggests that the tests are all taking ~25-50% longer in the flaking cases, e.g. due to contention with other test activity running in parallel, and that the RecursivePosts/IO test just happens to be so close to the configured timeout (45s?) that it flakes as a result.

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/62c715550ee24d8b24ef1069819719c2d3abafb0 commit 62c715550ee24d8b24ef1069819719c2d3abafb0 Author: Fabrice de Gans-Riberi <fdegans@chromium.org> Date: Mon Jun 18 19:36:35 2018 Filter out all remaining base tests on Fuchsia. This removes all the remaining disabled tests in the filter file for base tests on Fuchsia and instead filters each of them individually.
