# Sequential one-test-at-a-time integration run.
#
# Runs every Test* function under `galaxy/integration` in a fresh
# Docker state — preclean + single-test `go test -run` invocation —
# stopping on the first failure. Use this to:
#
#   - Diagnose which test brings the suite down on a slow or
#     overloaded Docker.
#   - Build confidence on a host that cannot run the full suite in
#     one shot.
#
# Slower than `make integration` (every test pays the bootstrap cost
# of its own backend/gateway/postgres) but each iteration is
# self-contained, so a flaky test cannot silently poison its
# successors.
#
# Environment:
#   STEP_TIMEOUT     per-test timeout (default 5m).
#   STEP_PRECLEAN    set to 0 to skip the preclean step before each
#                    test. Default is 1; only disable on a hand-cleaned
#                    Docker that you are sure has no leftover state.
#   STEP_VERBOSE     set to 0 to suppress `-v`. Default 1.
#
# Ryuk: this runner exports TESTCONTAINERS_RYUK_DISABLED=true. Ryuk
# does not start cleanly on the local colima setup; the per-step
# preclean handles leftover state by label. Override by setting
# TESTCONTAINERS_RYUK_DISABLED=false in the calling shell.
