add integration tests for route creation

[yapei]

@spadgett #1695 is substituted by this one, I should have addressed all comments. Could you please help review again? Thanks very much

/test e2e-aws

[spadgett]

It looks like the one integration test this adds is already covered by a spec test.

Any li on the page? This doesn't seem like a good helper and will break if any other li is introduced. It would be better to write one specifically for dropdown.

updated using existing code, WDYT?

This PR only move some common code to utils.view.ts, no other scenarios added
