Comment #5 on issue 3830 by laurent....@gmail.com: [Failing Test] Autotes TestHitCounter.testHitCountIncrements http://code.google.com/p/pharo/issues/detail?id=3830 I'm puzzled. I take the Pharo-1.2-AfterRunningTests image, open TestRunner and run all Autotest tests, sometimes (??) AutotestTestHitCounter.testHitCountIncrements fails. So to debug I've added a log on Transcript to check that AutotestHitCounter wrapper works: AutotestHitCounter>>run: aSelector with: anArray in: aReceiver self hit. Transcript show: thisContext sender asString; space; show: self hitCount asString; cr. ^ aReceiver withArgs: anArray executeMethod: method but then tests never fail; always green !! Remove/comment Transcript instructions, then sometimes the test fail again. So this come out of my knowledge - what should I check ?
