harness-writing/workflow
1
Identify Entry Points:
— Select functions that handle external input or complex data formats.
2
Write Minimal Harness:
— Create a basic harness that calls the target function with fuzzer-provided data.
3
Add Input Validation:
— Implement checks to reject invalid or meaningless inputs.
4
Structure the Input:
— Use casting or helpers like `FuzzedDataProvider` to create typed inputs.
5
Test and Iterate:
— Run the fuzzer, monitor metrics, and refine the harness based on results.
6
Handle Non-Determinism:
— Mock I/O and reset global state to ensure reproducible results.
