Kotlin: The Next Frontier in Metaprogramming
summary
Generates runnable UI tests for TornadoFX by parsing source with cast tree and the Kotlin PSI, building directed graphs of views and functions, and emitting TestFX scripts; AST-based locator avoids image ML and supports runtime-inserted randomized IDs. Project runs on the JVM, takes months of iterative work (three to five months for the parser phase), is open-source with a mapping-nodes branch, and currently produces simple click/write/verify tests while compositional state-checking remains in progress.
