Genpark Autonomous Test Mutation Coverage Scorer Skill

GenPark Verified Protocol License

Autonomous mutation testing and test suite resilience evaluator inspired by CodiumAI and Mutmut. Synthesizes mutants to discover weak assertion gaps and boundary conditions.

Features

• AST Mutant Generation: Generates syntactically valid mutated AST clones.
• Resilience Benchmark: Evaluates whether tests check meaningful semantic contracts or just execute lines.
• Zero External Dependencies: Standard library Python 3.9+.

Quickstart

from client import TestMutationCoverageScorerClient

scorer = TestMutationCoverageScorerClient()
report = scorer.evaluate_mutation_score(code, test_cases)
print("MSI Score:", report["msi"])
