Hi all, What results do you get when running all tests in Pharo and PharoCore 1.0 on Mac/Windows/Linux? Lukas has MCPackageTest>>#testUnload failing on Hudson (a Linux server, I assume). When running the tests locally on the Mac, the test BlockContextTest>>#testTrace fails. But only the first time. Apparently ContextPart>>#trace: is broken [1]. When I run all tests in Pharo1.0 on a Mac VM 4.2.3beta1U the first time I get no failures. When running the second time I get following failures: MCInitializationTest>>testWorkingCopy MCSnapshotTest>>testInstanceReuse ProcessspecificTest>>testDynamicVariable ProcessspecificTest>>testLocalVariable ReleaseTest>>testObsoleteClasses If I then run only the above, they all pass. So there is certainly something fishy with the tests or how they are run. I would like to have a reliable, green test suite for Pharo 1.0. Can you report the results you get including the VM/platform? Any idea why the results are not stable? Thanks, Adrian [1] http://code.google.com/p/pharo/issues/detail?id=2210
