The test required the parser to parse a payload that names an external entity and to leave the system identifier of that entity in the document. That is one way to keep the contents of the named file out of the document, and it is the way the parser behaves today, but it is not the contract. The contract is that the contents never arrive. Assert that instead: the contents reach neither the document nor the error. A parser that refuses the payload keeps the contract as well as a parser that parses it and leaves the entity alone. Behaviour does not change. The test passes against this branch and against the current parser.
xCAT-test/unit
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:
use FindBin;
use lib "$FindBin::Bin/../../perl-xCAT";
use lib "$FindBin::Bin/../../xCAT-server/lib/perl";
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
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.
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:
plan skip_all => "compute.subiquity.tmpl not found" unless -f $tmpl_path;
That guard never fires when the tree is intact.
