Testing UI5 apps, part 3.2

I’ve published the fourth part of my blog post series on “Testing UI5 apps” over at blogs.sap.com.
It essentially covers both headless- and multi-browser testing, along with some necessary-to-know Usefulities™ such as QUnit.only and opaSkip.
The hands-on code part is (as usual) on github, for this article on branch 03_mock-cov-useful.
