Hi, I updated GTDebugger to automatically show a diff in the debugger when an #assert:equals: fails. For example if you execute '(GTSUnitExampleFailingTest selector: #testMultiValuedStreaming) debug.' you get the debugger below. Also works when running tests from Nautilus/TestRunner. The context from where #assert:equals: was called is also automatically selected. [image: Inline image 1] Let me know if you run into any issues. Cheers, Andrei
