The Karma-Sauce-Launcher was using the wrong id
, and this was fixed on Github by this PR and released in NPM as version 0.2.5
Aditionally the saucelabs reporter has to be added to the gruntfile options, besides the existing ones or the default progress
.
So the bugfix I added to my package.json:
"karma-sauce-launcher": "~0.2.5"
and added this:
reporters: ['progress', 'saucelabs'],
in the Karma options.
