How does --test affect --require, or loaders? What happens to the REPL with node --test and no other arguments?

If NODE_OPTIONS='--test' is set, and the user doesn't control how node is invoked (via a shebang, for example), does this mean the user can never "undo" test mode?

This really feels to me like it should be an entirely distinct binary, rather than just a "mode" of the main node binary.

As this PR currently is --test hasn't been added to the allow list for NODE_OPTIONS so setting it there would throw an error.

ljharb · 2022-04-08T16:19:48Z

@richardlau thanks, if that's explicitly going to never be allowed there then that does mitigate that one concern, but all the others remain.

How does --test affect --require, or loaders? What happens to the REPL with node --test and no other arguments?

node --test doesn't launch the REPL. I haven't tried a loader, but --require seems to work fine.

If NODE_OPTIONS='--test' is set, and the user doesn't control how node is invoked (via a shebang, for example), does this mean the user can never "undo" test mode?

--test in NODE_OPTIONS explicitly errors out.

+    }

+    if (debug_options_.inspector_enabled) {
+      errors->push_back("the inspector cannot be used with --test");


Just a question: why is this? I can definitely see wanting to run the inspector for debugging while running tests.

A couple reasons:

First, it's trivial to run an individual file with the inspector flags. At this point, the CLI runner is just spawning Node child processes with no special flags.

Debugging through the CLI test runner is an awkward experience similar to the cluster module. Each test file will need a different debugger port. We would need to manage that logic as well as relay the correct information to users (I want to debug test X, I need to debug file Y, and connect to debug port Z). It also doesn't make sense to set something like --inspect-brk on a bunch of child processes.

I looked at a couple test frameworks, and they didn't seem to have a great story around propagating inspector flags to test files.

If someone is passionate about this, it can be added in the future. It just didn't seem worth it to me for an initial version given the previous points. I think it would make sense in the future to have configuration options for execArgv and argv of the child processes.

Can we use chrome's debugger blackboxing stuff to "hide" the test runner code when inspecting?

Possibly - I'm not sure though.
