#!/usr/bin/env bash
# test-contract.sh
#
# Runs the Soroban contract test suite with coverage, gas profiling, and optional fuzzing.
# Usage: bash scripts/test-contract.sh [--fuzz] [--coverage] [--gas] [--ci] [--build]
#
# Flags:
#   --fuzz      Run cargo-fuzz targets (requires nightly + cargo-fuzz)
#   --coverage  Generate llvm-cov HTML + lcov report
#   --gas       Emit per-test instruction counts via SOROBAN_GAS_PROFILE=1
#   --ci        Write GitHub Actions step summaries and set output variables
#   --build     Build optimized WASM artifacts (release profile, opt-level=z)
