It great having a CI system to check all our tests a passing, but I thought I'd go old school and run them from the TestRunner GUI and found in a fresh latest Pharo 7 there are "128 failures, 63 errors" This one is interesting... ArrayTest>>test0FixtureAsSetForIdentityMultiplinessTest | anElement res | self elementsCopyNonIdenticalWithoutEqualElements. anElement := self elementsCopyNonIdenticalWithoutEqualElements anyOne. self deny: anElement copy == anElement. "<<<<FAILS" where anElement ==> SmallFloat64 (1.5) so the deny fails. It seems that the test setUp is wrong since #elementsCopyNonIdenticalWithoutEqualElements does not return a collection (of elements for which copy is not identical ) without equal elements:" This seems like a permanent error rather than a transient one. How does this slip through CI testing? and what can be done about cleaning this up? cheers -ben P.S. With the loss of method version info is impossible to guess when this may have been introduced, to guess which Issue it was related to, to guess how I might approach fixing this myself.
