Metamorphic testing has uncovered real bugs in GCC, LLVM, Vulkan shader compilers, and ADAS simulators.
Metamorphic testing has found 147 confirmed bugs in GCC and LLVM, defects in commercial ADAS simulators used by automotive OEMs, and a fatal flaw in a…
Large language models are decent brainstorming partners for discovering test oracles, but they hallucinate properties and miss domain constraints.
You need to test a function where the correct output is impossible to know in advance. A route optimizer. A sentiment classifier. A physics simulation. You've…
Not all metamorphic relations catch bugs. Weak relations give false confidence while strong ones find real faults.
You wrote twelve metamorphic relations for your pricing engine. Every test passes. You feel good about your coverage. Then a customer reports that bulk…
Metamorphic testing lets you verify code correctness without knowing the exact expected output.
You ship a machine learning model that labels support tickets. Your test suite is green. Every test passed. None of those tests actually check whether the…
