# Main test runner for Dockercraft API tests
# Runs all test suites against the external APIs to verify they're healthy

# Usage:
#   ./tests/run_tests.sh                    # Run all tests
#   ./tests/run_tests.sh -m 1.21.1          # Test with specific MC version
#   ./tests/run_tests.sh -s mojang          # Run only Mojang tests
#   ./tests/run_tests.sh -s paper,fabric    # Run Paper and Fabric tests
#   ./tests/run_tests.sh --list             # List available test suites
#
# Exit codes:
#   0 = all tests passed
#   1 = one or more tests failed

Run API health and correctness tests for Dockercraft.

Options:
  -m, --mc-version <ver>    Minecraft version (default: auto-detect latest)
  -s, --suite <name>        Run specific suite(s), comma-separated
                            Valid: mojang, paper, fabric, forge, neoforge, bedrock
  -l, --list                List available test suites and exit
  -h, --help                Show this help

Examples:

  $(basename "$0") -m 1.21.1                    # All suites, MC 1.21.1
