This article presents a complete Python implementation of a Daikon-style runtime invariant miner, which automatically generates likely program invariants by observing program executions. The system includes instrumentation, trace collection, candidate invariant checking, and implication-based suppression, providing an approximate oracle for software testing. While these invariants are not guaranteed to be correct, they serve as effective tools for regression testing by detecting behavioral changes in code.
Background
Runtime invariant mining, pioneered by the Daikon system, is a technique for automatically discovering program properties by observing program executions. These properties can then be used as oracles for testing and verification.
