Description

3 years ago
Android reftest assertion count failure detection has been faulty for several weeks - bug 1267020. In the meantime, this failure has been happening with high frequency. See https://brasstacks.mozilla.com/orangefactor/?display=Bug&bugid=1267020&startday=2016-04-18&endday=2016-04-24&tree=all for some failures that the sheriffs noticed.

https://treeherder.mozilla.org/#/jobs?repo=try&revision=b556cb611378 shows what happens when Android assertion count mismatches are reported correctly - 336744-1.html fails about half the time.

In searching for a regression range, I noticed that the failure frequency varied widely from revision to revision - frustrating.

However, I finally found that prior to http://hg.mozilla.org/mozilla-central/rev/a57d3b17dcf8 (March 11), this test was skipped on Android!

Ryan -- Should I perhaps just add back the skip-if(Android)? ...with a reference back to this bug?

Go for it. I'd rather annotate the expected assertion range instead, but if they're varying wildly from run to run, seems doubtful it'd do much good in practice.

An assertion range might have worked, but I prefer the historical consistency of re-instating the skip-if.
