Test first/last is not important? Unit test either? What do you think? http://beust.com/weblog/archives/000477.html

* The name of the test should describe the requirement of the code
* There should be at least one test for each requirement of the code. Each possible path through of the code is a different requirement#
* Test the goal of the code, not the implementation

Discussion about naming the tests - http://www.codeaffine.com[..]14/03/17/getting-junit-test-names-right/ http://www.petrikainulainen.net[..]ting/writing-clean-tests-naming-matters/

http://googletesting.blogspot.com.au[..]esting-on-toilet-test-behaviors-not.html <- Test behaviour, not method. This will make your tests more resilient since adding new behaviors is unlikely to break the existing tests, and clearer since each test contains code to exercise only one behavior.
