lerna exec --parallel does not return exit codes for each project

[sipayRT]

I'm trying to run tests in parallel by command npx lerna exec --no-bail --parallel -- node scripts/some-tests-runner.js.
How can I get exit codes (or execution result) for each project?

Expected Behavior

Ability to get execution result for each run

Current Behavior

Common exit code for all runs

Possible Solution

Maybe you can add to process result information about each child-process from projects. For example:

{
  status: 1,
  results: [
    {
      name: 'project1'
      status: 0
    },
    {
      name: 'project2'
      status: 1
    }
  ]
}

Your Environment

| Executable | Version |
| ---: | :--- |
| lerna --version | v3.14.1 |
| npm --version | 6.2.0 |
| node --version | 8.6.0 |

| OS | Version |
| ---: | :--- |
| macOS Mojave | 10.14.6 |

Lerna is not a test runner. Try Jest, it works really well with the constraints you've identified.

@evocateur em... okey, I can change example to npx lerna exec --no-bail --parallel -- node do-something.js.
Or lerna is not do-something-runner?

If you want the functionality, build it yourself. There are more than enough granular @lerna/* packages to get you 80% of the way there already.
