KellyMichels d93a86d836 test: cover target-argument parsing across the scripts (phase 4) ... Part of #26. This layer has regressed more than any other - bare vs dashed keys, 'all' expansion, and whether a bad key fails loudly or quietly selects nothing. 42 tests over three guarantees: - Running bare shows usage and exits non-zero, for all ten target-taking scripts. Some of these used to mean 'do it to everything' when run with no args, which is how an unintended full backup or deploy happens. - An unknown key fails loudly. Exiting 0 having selected nothing is the dangerous outcome: a typo'd key in a scheduled task looks like a successful run that backed up nothing. - A leading dash is stripped before the lookup, so -myapp == myapp. Asserted via a dashed *unknown* key, so the error must name 'x' rather than '-x'. Plus zkill's own resolution: bare key, dashed key, several keys, 'all' and '-all' expanding to projects that have a ports.dev, edge/docker stacks skipped, and -Port overriding the configured port. Safety: the tests run the real scripts as child processes, so they are confined to paths that exit before doing any work. Only zkill runs with a valid target, because the fixture's dev ports (59990/59991) are deliberately unused and its localRoots do not exist - it finds no listeners and kills nothing. zdeploy, zbackup_ec2, zec2, zec2online, zrepair, zstop, zstart and zbackup are never invoked with a real target; that is integration territory needing a disposable server. Each test runs against an isolated temp installation - the .ps1 files copied beside a fixture zconfig.json - so nothing touches this repo, no real config is read, and the suite passes on a machine that has never been configured. That also makes it independent of the ZCONFIG seam in #27, so the PRs can merge in any order. Verified by mutation testing: removing zkill's all-expansion, dash tolerance and no-args guard, making an unknown key exit 0, and letting underscore comment keys leak in as projects each turn the suite red (2/1/2/16/4 tests). Both mutated files confirmed restored byte-for-byte.		2026-07-26 12:24:30 -05:00
