Smoke tests

Quick run through of main features to check things look OK.

In computer programming and software testing, smoke testing (also confidence testing, sanity testing,[1] build verification test (BVT)[2][3][4] and build acceptance test) is preliminary testing to reveal simple failures severe enough to, for example, reject a prospective software release. Smoke tests are a subset of test cases that cover the most important functionality of a component or system, used to aid assessment of whether main functions of the software appear to work correctly.
