Start test names with “should”

The purpose of a test is not just to enforce some behaviour on the code under test. When the test fails it also should provide enough information to understand which behaviour failed, where it failed, and (at least superficially) why it failed. If the only output of a failing test is just a binary value like “FAIL”, that test is only giving one bit of information to the developer. A good test framework will also print the test name and a call stack. We can’t change the call stack much, at least not without changing the semantics of the test, and how to actually write the test itself is a whole other story, but what does a useful test name look like?
