Nightwatch.js automagically uses Firefox. Well wut.

Hello dear people. I am currently fiddling with nightwatch and I couldn’t yet even get it running properly when I’d like to test for a single-browser … I’ve set up some code that manually manages and installs the accommodate versions of ChromeDriverfor OSX (since the start_process option doesn’t do that properly) using selenium-standalone. Well that works so far … anyhow for some reason, night watch ALWAYS appends the Firefox capability, which really sucks for me… See this paste for a deeper insight.

do you use -e chrome in command line ?

I spent an hour on this so I thought it might help someone else in the future. I had the exact same issue. I found that the nightwatch.json file in the tutorial found here (http://nightwatchjs.org/getingstarted#browser-drivers-setup) wasn’t quite right.

I had to move the “desiredCapabilities” entry and place it INSIDE of the “default” entry:

`
“test_settings” : {

"default" : {
     
    "desiredCapabilities": {
        "browserName": "chrome",              
  }
}    

} `

After I fixed this, I didn’t need Firefox installed on my machine and could only use Chrome.
