To echo CLI arguments in Node.js test fixtures, use a dependency-free CLI that reads process.argv and prints each argument prefixed with TEST_OUTPUT: for verification. It emits TEST_OUTPUT:no-args when no arguments are provided.

The best way to verify argument handling in a CLI debugging workflow is to pass test inputs to an echo utility that prints each forwarded argument back to stdout, allowing you to validate single and multiple argument processing without complex setup.

Yes, you can use a dependency-free Node.js script to debug process.argv. The CLI reads process.argv and outputs TEST_OUTPUT:<arg> for each provided argument, or TEST_OUTPUT:no-args when none are provided.

Yes, the echo CLI handles zero arguments by emitting TEST_OUTPUT:no-args to stdout, ensuring your test fixtures can reliably verify behavior even when no input arguments are forwarded to the script.

If your forwarded CLI arguments are not showing up during testing, an echo fixture can help verify the process.argv pipeline by printing TEST_OUTPUT:<arg> for each argument received. If none are detected, it outputs TEST_OUTPUT:no-args.
