I would like to understand if, - it makes sense to have Karate integration with SauceLabs - Benefits if that is an Yes
Also, if i want to implement the integration what is the approach i should use.
I am planning to mimic the similar implementation using Selenium remote web driver. Please let me know if this is the only approach that can be taken or there is any other way out for this.
Yes, if SauceLabs conforms to the spec - refer to the documentation for webDriverSession: https://github.com/intuit/karate/tree/master/karate-core#webdriversession
Note that this has been proven to work with Zalenium: https://github.com/intuit/karate/tree/master/karate-core#webdriverurl
And also AWS Device Farm: https://twitter.com/ptrthomas/status/1222790566598991873
Please note that if you are ok to use only Chrome, the Docker approach may give you a better experience, but you can decide: https://github.com/intuit/karate/tree/master/karate-core#karate-chrome
