The shell, discover, standby and runcmd destinies load the Genesis kernel
through the same UEFI script as an osimage kernel. setstate asks for a shim
with the os of the node, so an install source answers for a kernel that no
distribution signed.
The new node keeps the install source of the first node of the test, so both
shims are on disk and the order decides the answer. Two assertions of twelve
fail: the script names /install/alma9.8/x86_64/EFI/BOOT/BOOTX64.EFI.
The nodeset helper takes currstate and provmethod, so the node reads as the
shell destiny it is.

Unit tests. These run against the source tree only -- no xCAT installation, no
running daemons, no management node.
They are executed on every pull request by the xcat_test GitHub Actions workflow,
which calls run_unit_tests() in github_action_xcat_test.pl:
prove -r xCAT-test/unit
You can run exactly the same thing from a clean checkout:
cd <xcat-core checkout>
prove -r xCAT-test/unit
What belongs here
A test belongs in unit/ when everything it needs is in the checkout: plugin and
library sources, kickstart/preseed/subiquity templates, postscripts, packaging
metadata. Such a test asserts on rendered output or module logic and reaches the
repository root through FindBin:
Because of those FindBin paths the tests only work from a source tree. The copy
installed under /opt/xcat/share/xcat/tools/autotest/unit is not a substitute --
../.. resolves to /opt/xcat/share/xcat/tools there and the tests die or silently
skip. The CI takes a copy of the checkout before the build for this reason; see
preserve_source_tree().
What does not belong here
Tests that build RPMs, create Linux namespaces or start service binaries belong
in ../native. They run explicitly on a suitable host,
outside the default unit suite.
Anything that needs an installed xCAT, a populated /install, a real service binary
or a live daemon. Those go in ../integration and run on
a management node through xcattest. Both suites run on every pull request -- the
workflow installs xCAT on the runner and then runs the ci_test cases against it --
so putting a test in integration/ does not cost it CI coverage. What differs is what
each suite is allowed to depend on, and that unit tests also run standalone from a
bare checkout with no xCAT at all.
Shell-script unit tests belong in ../bats
and run with BATS. Do not add Perl .t tests that grep shell source when the
behavior can be exercised by sourcing a shell library or script and shadowing the
external commands it calls.
The distinction matters because a test that needs an absent environment does not fail
-- it calls plan skip_all and reports as skipped. A handful of those in a suite of
several hundred assertions is easy to stop reading. Keeping the two kinds in separate
directories means a skip in unit/ is a real signal rather than routine noise.
Guarding on a source file, on the other hand, is fine and common here:
planskip_all=>"compute.subiquity.tmpl not found"unless-f$tmpl_path;
