- name: Build VM image
# The test always rebuilds this image itself (so the baked-in
# binaries match the source under test), but we build it here
# first so that rebuild is a build cache hit instead of a cold
# build that eats the go test -timeout budget, and so a broken
# image build fails earlier with a clearer error. The Makefile
# uses ./tool/go, the same toolchain the test's rebuild uses;
# a build with a different toolchain here would warm nothing.

- name: Run natlab integration tests
# With a warm build cache the test takes well under a minute.
# The timeout matches natlab-test.yml and exceeds vmtest's own
# 10 minute test context, so that a hung node fails through the
# test's bounded waits, which dump the node's logs, rather than
# through go test's timeout panic, which dumps nothing useful.
