Dale we run the tests simply rewriting runCase as runCase | original | (self doSilently) ifFalse: [ ^super runCase ]. original := MetacelloPlatform current bypassGoferLoadUpdateCategories. [ MetacelloPlatform current bypassGoferLoadUpdateCategories: true. ^ SystemAnnouncer uniqueInstance suspendAllWhile: [ super runCase ] ensure: [ MetacelloPlatform current bypassGoferLoadUpdateCategories: original ] but it seems that we do not have the same behavior between the two runCase | original | (self doSilently) ifFalse: [ ^super runCase ]. original := MetacelloPlatform current bypassGoferLoadUpdateCategories. [ MetacelloPlatform current bypassGoferLoadUpdateCategories: true. ^ super runCase ] ensure: [ MetacelloPlatform current bypassGoferLoadUpdateCategories: original ] So we will run all the tests Stef
