## Test runner entry point. Run with:
##   godot --headless -s res://tests/run_all.gd
##
## This script discovers and runs all test files in the tests/ directory.
## For a quick start without GUT installed, this manually instantiates
## each test script and calls every test_*() method it defines.
## Assertion failures are emitted via push_error ("ASSERT FAILED ...").
