Method-level Change-proneness: A Better Metric for Black-box Test Suite Minimization

Kazi Sakib, Md Siam

Method-level change-proneness provides a stronger guide than class-level metrics for shrinking black-box test suites.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

MCTM achieves 0.93 accuracy and 0.94 fault detection rate on average, significantly outperforming class-level CP and similarity-based approaches while maintaining superior efficiency.

C2weakest assumption

The dependency between test cases and methods can be accurately determined by analyzing the test-code call-graph, allowing reliable scoring of association with change-prone methods.

C3one line summary

MCTM applies method-level change-proneness from version history and call-graph analysis to minimize black-box test suites, reporting 0.93 accuracy and 0.94 fault detection rate on 15 Java projects with 635 buggy versions.
