Hi there, I am trying to use Hapao to check test coverage in the String class and have run across some trouble. To begin, I loaded Spy2 and Roassal2 using the following code: Gofer new smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; package: 'ConfigurationOfRoassal2'; load. (Smalltalk at: #ConfigurationOfRoassal2) load. Gofer it smalltalkhubUser: 'ObjectProfile' project: 'Spy2'; configurationOf: 'Spy2'; loadStable. Hapao then showed up in the "World" menu, and I selected it. I chose "Hapao @ class ... " and entered "String". Hapao starts running tests, but before long a debugger comes up with the error: KeyNotFound: key #testClassComment not found in MethodDictionary . IF I click "Proceed", other keyNotFound errors come up. This is in a 50524 image. Is there something wrong with the way I am invoking Hapao? Many thanks, Sheridan
