What about passing detox command line args? Will those work?

We can think of a way doing this. Although, in this version I wasn't aiming to provide this. If this is mandatory, we can discuss the approach

Sorry, misread your comment. What do you mean by "detox cli args"? Can you make an example?

I think it is, the feature is not 100% usable without it.

Which flags are important?
In the previous version there were no recommendations regarding flags so kept it out of scope. However, I'm fine adding important flags to make jest support even better 💪 .

@rotemmiz what is the goal?

  • tests can access CLI arguments
    or
  • detox can access CLI arguments

If we talk about the second one, then it already works like this (commander parses arguments before passing them to test runner)

You're right, but we execute a child process and these argument are not being passed into it.
cp.execSync(command, {stdio: 'inherit'});
We probably just need to pass them on...

Oh, now I see. Indeed, we just need to pass arguments to the child process. Then there will be no point in passing all these flags in the command itself

Seems like jest doesn't support allow custom CLI parameters. The only approach I see is to use environment vars.

Using ENV vars will imply changes on the mocha part and the way test cases gets parameters overall.

UPD: I can update argparse library and CLI so instead of additional flags it'll create one-time ENV variables. For user it'll be still the same, all mapping will happen under the hood.

Nice idea @Kureev, thank you so much for your efforts here 👍

command = `node_modules/.bin/${program.runner} ${testFolder} --runInBand`;

default:
