can use this syntax to run it exactly as the test harness would:

```text
$ python tools/test.py -v --mode=release parallel/test-stream2-transform
$ python tools/test.py --mode=release parallel/test-stream2-transform

Can we add a -J? Given that it says "exactly as the test harness would" we should probably be exact:

-$ python tools/test.py --mode=release parallel/test-stream2-transform
+$ python tools/test.py -J --mode=release parallel/test-stream2-transform

LGTM otherwise.

I think it would be run "exactly as the test harness would" either way given that tools/test.py is the test harness, regardless of the options.

I assume the test harness means make test, otherwise that part of the sentence is kinda meaningless. The reason I think this is necessary is that using -J can cause subtle bugs (when tests interact with each other), and that is impossible to debug if you don't use the flag by default.

Yeah, I agree with that if we are talking about running multiple tests. But that sentence is about running a single test, isn't it? Do I miss the point?

Wouldn't a PR changing -J to default (with -j1 as the opt-out) make sense?

Maaaybe, I think I'd be +1 on that, but I suspect it might be contentious...

Other option, a wrapper script test-ci (.sh & .cmd).
This one I'm doing

Doesn't that duplicate the Makefile and vcbuild.bat test-ci target? What's the gain?

It'll take $*, so it's useful for single files, or single suits.
I don't know about make test-ci but vcbuild test-ci builds first (with Feet of clay), very demotivating.

Also, can you please avoid using personal pronouns like "you"?

EDIT: on the other hand, that's how this document is already written, and such wording is common in it.
