# script/test: run the test suite.
#
# -timeout is applied by `go test` per package, not to the run as a whole, so
# it only has to clear the slowest single package. When this budget was set
# that was internal/handlers, measured in a cache-defeated builder stage on the
# 48-core shared build host (2026-08-18); load- and host-dependent, not
# invariants:
#
#   16.9s                  host load 5-20, GOMAXPROCS 48
#   45.9s / 47.3s / 49.0s  three runs at deliberate host load 31-73
#   30.6s / 39.7s          host load 5-20, GOMAXPROCS 6 / 4
#   67.3s / 97.5s          host load 5-20, GOMAXPROCS 2 / 1
#   67.3s                  GOMAXPROCS 4 at deliberate host load 52-68
#
# The old 30s budget was breached by every loaded run and by every GOMAXPROCS
# at or below 6; at GOMAXPROCS 4 it failed outright ("panic: test timed out
# after 30s"), reproduced on 33e4fa4 with no other change.
#
# 90s matches the org-wide backstop in REPO_POLICIES.md and is sized here
# against the figures above: the worst case under native parallelism is 49.0s,
# and the compound GOMAXPROCS-4-under-load case at 67.3s sits at 75% of it.
# The one figure above 90s is GOMAXPROCS 1, a synthetic core floor rather than
# a condition CI runs under. If a CPU-limited runner ever puts a real run near
# 67s, that is the datum to revisit the org figure with.
#
# Those figures predate tests hashing the admin password at 1 MB instead of
# 64 MB (https://git.eeqj.de/sneak/webhooker/pulls/404). After that change, in
# a cache-defeated build at host load 41-55 (2026-10-02), internal/handlers
# took 10.0s and the slowest package was internal/database at 16.2s.
#
# -p 4 -parallel 8 keep the run under 2 GB of memory: at most four test
# binaries build or run at once, each with at most eight parallel tests. Under
# -race every test binary and every link costs a few hundred MB, so the
# defaults (one per core) add up to several GB on a many-core host.
#
# No -v: the Docker build cuts each step's log off at 2 MiB, and verbose output
# from the whole suite passes that before a failure is printed. Without it, go
# test prints one result line per package and, for a package that fails,
# everything its tests wrote, application log lines included.
