The dhcp-named-file scenario said its file name came from an observed DHCP acknowledgement. Nothing here speaks DHCP: the caller spells the name, dhcptest asserts that xCAT sends it, and this asserts it can be fetched. The scenario table had fallen behind four files, and two real gaps were unwritten anywhere: the x509cert form of getcredentials, whose CSR a wire test cannot fabricate meaningfully, and the absence of copycds -- the install tree the nodes point at is fabricated.
xCAT-test
Unit tests that run from the source checkout are split by implementation language:
| Test type | Location | Runner |
|---|---|---|
| Perl unit tests | xCAT-test/unit/*.t |
prove -r xCAT-test/unit |
| Shell unit tests | xCAT-test/bats/*.bats |
bats -r xCAT-test/bats |
| DHCP wire tests | xCAT-test/dhcptest/ |
python3 -m unittest discover -s tests, then dhcptest run -i <nic> <conf> |
| CLI functional tests | xCAT-test/autotest/testcase/ and xCAT-test/autotest/bundle/ |
xcattest -f <cluster.conf> -t <case> or xcattest -f <cluster.conf> -b <bundle> |
Use Perl .t tests for Perl modules, Perl scripts, templates, and repository
artifacts. Use BATS tests for shell-script behavior that can be exercised from
the checkout by sourcing a shell library or script and shadowing external
commands.
Shell behavior should not be tested by Perl tests that grep shell source. Put
those tests under xCAT-test/bats instead.
dhcptest is the odd one out: its Python unit tests and dhcptest validate
run offline like the others, but its point is the third column -- driving real
DHCP transactions on a provisioning NIC and asserting on what came back. It
talks to the server only over the wire, so it is agnostic to which DHCP
implementation is answering and to xCAT itself.
See unit/README.md, bats/README.md and dhcptest/README.md for the
detailed rules for each suite.
