- Around line 45-57: Update parseArgs to validate unknown hyphen-prefixed
arguments before the --help/-h branch, so combinations such as --bogus --help
exit non-zero and report the unknown flag. Add a subprocess test covering this
combination and its rejection status.
In `@tests/plugin-audit.test.mjs`:
- Around line 21-33: Extend the help tests for both --help and -h to invoke the
audit with a deliberately missing plugin directory, then assert exit status 0,
usage output on stdout, and an empty stderr stream to verify help exits before
filesystem work.

Thanks for this, @Divesh-Kshirsagar. I am reviewing as code owner for tests/, so this is about tests/plugin-audit.test.mjs only.
Good, focused suite. Six cases cover --help and -h exiting 0 with usage, an unknown flag rejected, a valid directory actually running the audit, help exiting before a missing directory is touched, and the --bogus --help precedence. One thing I checked before anything else: a node:test file can pass without running if the harness only imports it, so I confirmed test-all.mjs detects from 'node:test' (line 130) and runs the file through node --test (line 131). These execute for real. I ran it on 4e0bf9a: 6 tests pass.
Two things, both minor.
1. The valid-directory test ties this suite's stability to another plugin's source. At 42-50 you run the audit against plugins/apify and assert r.all matches /direct global fetch/i. It is a real end-to-end control and I like that it proves the audit actually ran, not just the flag paths. The cost is that the assertion depends on apify's code keeping a global-fetch finding. Fix apify to stop using global fetch, or rename the plugin, and this test goes red for a reason unrelated to argument handling, which is the whole subject here. Pointing the run at a throwaway fixture plugin directory the test writes and removes, or asserting only that a valid directory produces audit output with no flag error, keeps the control without the coupling. A test that breaks when an unrelated file changes teaches the next reader to ignore it.
2. The precedence test does not prove help was suppressed. At 61-65 you assert notEqual(r.status, 0) and that stderr carries the unrecognized-flag error, which shows the flag was rejected but not that --help was skipped. I measured node plugin-audit.mjs --bogus --help: exit 1, stdout empty, error and usage on stderr. The help path that exits 0 prints usage to stdout, which your own --help test at 21-26 asserts on stdout, so assert.equal(r.stdout, '') and assert.equal(r.status, 1) here are what actually prove --help never ran. Without them, a later change that prints help to stdout and still errors with a non-zero exit keeps this test green while the precedence is broken.
On CodeRabbit's note at line 33, to add a pre-filesystem help regression: that is already here. The test at 52-59 loops ['--help', '-h'] against a missing directory and asserts status 0, usage on stdout, empty stderr. Its second note at line 63 is the same point as 2 above.

Converts good-first-issue #2771 cleanly, and the acceptance criteria in that issue all hold. @Scott-Emberson reviewed One thing that arrived right behind you, so you hear it from me rather than from a conflict: #2778 merged tonight and adds Suite on main after merging: 3860 passed, 0 failed. Merged. 🚀 |

What does this PR do?
Adds argument parsing to
plugin-audit.mjsso--help/-hdisplay usage information and unrecognized flags are rejected before any filesystem access. Existing positional plugin-directory behavior is preserved, and CLI subprocess regression tests cover the new behavior.Related issue
