# Final pass banner for `zig build test`.
#
# build.zig wires this as the last dependency of the `test` step, depending on
# every host-test run, so it executes only after they all pass. It is handed
# the exact list of source files addHostTest wired (so the count is derived
# from the build graph itself and can never drift from the suite), counts the
# `test "…"` / `test {` blocks across them, and prints one green line. Reaching
# this step means every wired test already ran green, so the count is the
# number that passed. Per-module detail: `zig build test --summary all`.
#
# Args: $1 = active -Dtest-filter substring ("" when none); $2.. = source files.
