Add --json flag to programmatically consume the test output

[ide]

I want to use this with arcanist so making it easy to parse the output is helpful.

[cpojer]

yes! I'll look into what format we are using for arc unit and whether I can just open source that :)

[mhagmajer]

@cpojer, Any updates here?

[cpojer]

Yes this is planned but I wish I had 10 hours more per day to work on jest!

[cpojer]

This will be in 0.6.0.

[ide]

Thanks @cpojer!

@ide care to try this out to see if it works for you? I wanna tag 0.6.0 tomorrow or so.

[ide]

It's going to take me awhile to hook this up to arcanist (need to write a bunch of PHP) so go ahead and publish it.

The --json flag works for a small project of mine though :)

$ npm test -- --json

> dash-button@1.0.0 test /Users/ide/Code/dash-button
> jest "--json"

Right, the question is more like:

• does this work for you (or work at all :D )
• does it give you all the info you need

[ide]

Yeah it should, just trying to fill in the main fields here: https://secure.phabricator.com/diffusion/ARC/browse/master/src/unit/ArcanistUnitTestResult.php;e51e1c3d44640d60c9843c6f41ee06434cadf697$150. Name, result, and duration are the most important and looks like those are covered :)

    return array(
      'namespace' => $this->getNamespace(),
      'name' => $this->getName(),
      'link' => $this->getLink(),
      'result' => $this->getResult(),
      'duration' => $this->getDuration(),
      'extra' => $this->getExtraData(),
      'userData' => $this->getUserData(),
      'coverage' => $this->getCoverage(),
    );

Cool. I mean this is the same code we use at FB for arc/phabricator so I guess this is fine.
