crashtest is a built-in regression suite for crashlink that scores the decompiler's output by recompiling it and comparing opcodes against the original bytecode.
Run it with just test (full suite including pytest) or crashtest auto / python -m crashtest auto to run and build the site. Must be called from the repo root.
Each test case shows the original Haxe source, decompiled output, and IR. The opcode comparison recompiles the decompiled code with haxe and scores method-level similarity. Cases below 70% similarity are marked as failures.
