With Polymer 2.0-preview, patched t2ym/web-component-tester-istanbul#wct6 and t2ym/web-component-tester#istanbul can properly collect coverage information.

[t2ym]

With Polymer 1.8.0, still timed out errors are observed on Sauce Labs tests. No errors of tests themselves are observed.

Some of the socket.io messages are dropped in the middle by some reason.

[t2ym]

Fixed with patched components:

t2ym/web-component-tester#istanbul
t2ym/web-component-tester-istanbul#0.10.1-wct6.6
t2ym/polyserve#0.16.0-istanbul.4
t2ym/socket.io#istanbul
t2ym/socket.io-client#istanbul
t2ym/engine.io-client#istanbul
t2ym/engine.io-parser#istanbul
