# Test basic fuzzing mutator behavior.

# fuzz_test.go has two fuzz targets (FuzzA, FuzzB) which both add a seed value.
# Each fuzz function writes the input to a log file. The coordinator and worker
# use separate log files. check_logs.go verifies that the coordinator only
# tests seed values and the worker tests mutated values on the fuzz target.
