No failing test cases were found.

run_fuzz_tests: finished with exit status 0

The script for running fuzz tests is the following:

#!/usr/bin/env bash
set -eo pipefail

main() {
  need_cmd simplex
  need_cmd tee

  local filter="${*:-all}"
  filter=${filter//[^[:alnum:]_.-]/_}
  filter=${filter:0:120}

  local log_file
  log_file="$(date +%Y-%m-%d_%H-%M-%S)_${filter}_$$.log"
  local status=0

  say "saving output to $log_file"

  # Include stderr: the test runner writes its progress and summary there.
  simplex test --fuzz "$@" --test-threads 10 --no-fail-fast -- --release --show-progress counter 2>&1 | tee "$log_file" || status=$?

  say "finished with exit status $status" | tee -a "$log_file"
  return "$status"
}

say() {
  printf 'run_fuzz_tests: %s\n' "$1"
}

err() {
  say "$*" >&2
  exit 1
}

need_cmd() {
  command -v "$1" > /dev/null 2>&1 || err "need '$1' (command not found)"
}

main "$@"

!/usr/bin/env bash
