Testing?

[timjacobi]

It would be interesting to see how you test this. Could you provide an example? Thanks

Testing of what? For automated integration/acceptance testing of the UI and whole app, I'd suggest to look at Vaadin TestBench. You can go with plain Selenium as well, but TestBench has some nice helpers that makes building test scripts faster.

Check e.g. this example project: https://github.com/mstahv/tb-page-object
