Read this Python function, synthesize representative inputs, execute it in a sandbox, capture current behavior, and generate a runnable pytest file covering normal cases, edge cases, and exceptions.
A pytest file with multiple behavior-based test cases that can support safe refactoring.
Analyze this Python class and its key methods, infer input combinations across call paths, record return values, side effects, and exceptions, and output pytest tests to preserve behavior after refactoring.
A set of characterization tests for class methods covering major call paths and observable behavior.
Before I refactor this Python module, automatically generate characterization tests; explore diverse inputs, identify non-obvious output patterns, and produce a well-structured pytest file.
An executable regression test suite that helps quickly detect behavioral drift during refactoring.
