When I launch protractor conf.js and this file needs to launch multiple spec files (like below), some of them are (randomly?) skipped. It works quite well when I run each spec separately.

  specs: [
    'tests/test-1-*.js',
    'tests/test-2-*.js',
    'tests/test-3-*.js'
  ],

What can I do to run all tests without any being skipped?
