How to test Polymer 2 components with Protractor when /deep/ will be deprecated?

[peter...@gmail.com]

My organization is going to be moving to Polymer 2 and with that they will have to move away from the shady dom to the shadow dom. I do know that /deep/ is being deprecated? Is there going to be something that will substitute for /deep/ that we can use in place when using Selenium and Protractor and Mocha?

I will reply with something i found on slack overflow

"The piercing selector is being dropped (/deep/ and >>>). There's currently no other alternative to search through the whole DOM with a single query. The current solution is to implement a custom selector taking multiple CSS segments to search each context"

The more important question... why do you feel you need /deep/ to test components?

We have a website that in each page there are multiple components, so we need to run acceptance tests to pierce each component and test them

Sounds like you are over complicating things... The component tests should cover components styling and CSS (including CSS variables that can be affected externally)... Integration tests (and beyond) shouldn't care about that... End To End or Integration tests should just be confirming proper input nets proper output (or page/view changes etc).
