title: Can I run Nightwatch js in paralell with a different env per worker?
body: <p>I'm currently using Nightwatch js to run my E2E tests in paralell.</p>
  <p>The issue I'm having is that my tests share the same database, which is causing me problems with shared data being rewritten across different tests/workers, resulting in flaky tests.
  I thought about running each test worker with its own database, but I'm not sure how to do it in practice. My starting point would be having different settings for the test databases, each on a night-watch env which can be accessed by the individual workers, but so far I've not found if this would be possible.</p>
  <p>Any ideas?</p>
