Parallel environment is not working on windows powershell

[mostmentor]

Description of the bug/issue

When I try to run https://nightwatchjs.org/guide/running-tests/parallel-running.html#via-workers-multiple-environments I got error "Invalid testing environment specified:"

I found this can be fixed by just update line 133 in lib/runner/cli/cli.js to be : - this.testEnvArray = this.testEnv.split(' ');

After updating this it started but the test is running default only

Command to run

nightwatch -e firefox,MicrosoftEdge,default --parallel 30
