In a freshly downloaded build 60224, I open TestRunner and run all tests. At run 418 I get a dialogue asking for the Author. To me that seems wrong. I don't want any code changes made during testing to have my normal identification on them. Tests invoked from Test Runner should be author-tagged something like 'TestRunner' or 'TestRunner-BenComan'. The question arises in this particular case due to... RPackageMonticelloSynchronisationTest >> setUp ... Author fullName ifNil: [ Author fullName: 'Tester' ]. Minor point... this check actually is a bit pointless since #fullName invokes #requestFullName that presents the dialog. And #fullName will *never* return nil. At a minimum it returns 'Anonymous'. First step would seem to be wrapping TestCase>>runCase: with Author useAuthor: 'TestRunner' during: [ .... ] But further. I envisage a time when TestRunner doesn't block the UI, so I can happily browse around the system and code while TestRunner is doing its thing. Obviously the system is not set up to have two parties (myself and TestRunner) both updating code in the system, but changing the state of the global Author uniqueInstance like this... Author>>useAuthor: aString during: aBlock ^ self uniqueInstance useAuthor: aString during: aBlock would itself seem to a big impediment. It would be good if "Author" was dependent on the context of the call chain. This would seem a requirement for one day having two people working in the one Image (is this a possible use case where someone is using a remote debugger while another person is using the standard UI?) So my second proposal is for Author>>fullName to invoke a Notification mechanism to determine #fullName. Something like... Notification subclass: AuthorRequest Author>>#fullName ^ AuthorRequest new signal instanceVariables: 'contextFullName'. Author>>useAuthor: tempAuthorFullname during: aBlock [ block ] on: AuthorRequest do: [ :noti | noti contextFullName: tempAuthorFullname ] with only unhandled AuthorRequests returning "Author uniqueInstance basicFullname". Thus code changes are not constrained to be assigned to a global author. Not that we *yet* have multiple people working in one image, but one more impediment is removed - step by step. What concerns would there be? cheers -ben
