#!/bin/bash

# HOW TO USE: This is a wrapper around busted. Pass "gc" as the first argument for testing the
# garbage collector. Except for "gc", the command-line arguments are the same of busted
#
# EXAMPLES:
#   ./run-tests
#   ./run-tests -k
#   ./run-tests spec/coder_spec.lua

echo "--- Test Suite ---"

# We encourage using -no-keep-going by default. Sometimes the test suite is failing because of
# something silly such as forgetting to run make and in those cases there is a desire to interrupt
# the test suite with Ctrl-C. With --keep-going (the default busted behavior) you need to press
# Ctrl-C multiple times and one of those Ctrl-C's will likely kill the busted process itself,
# meaning that the "teardown" routines are not run. On the other hand, with --no-keep-going we only
# need to press Ctrl-C once and busted usually gets to exit gracefully.
FLAGS=(--verbose --no-keep-going)

# To speed things up, we tell the C compiler to skip optimizations. (It's OK, the CI still uses -O2)
# Also, add some compiler flags to verify standard compliance.
