From @usergenic 's comment: #155 (review)
See if this fixes the test issue.

LGTM if the tests are green :D

@usergenic Tried to use comma separated list but it didn't work. Can you help us to figure out the right command to use?
Also noticed there was a polymer-cli release 3 days ago so maybe something was changed there.

[notwaldorf]

Now it's complaining these values don't match:

windows 10 microsoftedge 17,macos 10.13/safari@11 Tests failed: Unsupported
OS/browser/version/device combo: OS: 'Windows 10', Browser: 'microsoftedge', Version: '17,macos 
10.13/safari@11.', Device: 'unspecified'

[usergenic]

I was wrong about comma separated values.

I haven't 100% confirmed the history but given the usage, the argument in cli's test command code should have been specified as 'multiple: true' but it wasn't-- I think a version update in recent package lock refresh must have brought in change to command-line-args library which now enforces single values unless specified as multiple.

I tested the change locally and am going to try to get fixed in next release Polymer/tools#515

[usergenic]

Tested fix by making -s "multiple: true"...

λ npx polymer test --module-resolution=node --npm -s 'windows 10/microsoftedge@17' -s 'macos 10.13/safari@11'

@usergenic Awesome! Thanks for looking into it.

@frankiefu @notwaldorf wct 6.7.0 and polymer-cli 1.7.4 have both just been published which should solve this issue, i.e. multiple -s arguments accepted again.

@usergenic Thanks!
