# Test runner — discovers every tests/**/*.sx, runs each via `$SX run`, and
# reports per-test ok/FAIL. Exits 0 only when every test passes.
#
# A test passes iff `$SX run <file>` exits 0 (compile failures count as a
# failure too). Each test program asserts its own invariants — e.g. via
# process.assert — and exits non-zero on failure.
#
# Locate the compiler via SX (overridable); defaults to the sibling sx repo.
#
# SQLite needs no flags here: the sx library ships it (vendors/sqlite),
# declared as a `#import c` unit — `sx run` compiles (cached) and loads it
# as a priority symbol target; the version assert in tests/sqlite_smoke.sx
# proves the OS copy never shadows it.
