What is a 'test'? By definition, "a critical examination, observation or evaluation. A procedure intended to establish the quality, performance or reliability of something".
So this is why it's called a test - because it is.
And defined, for mine, by Sri Lanka's belligerent and determined batting on day four. I get why most New Zealand fans will be disappointed after yesterday's historic no-wicket-day at the Basin Reserve but, from a purist's perspective, it was exactly what the sport is about and also what it needs to keep this vital format alive and valid.
How easy would it have been for the Sri Lankans to throw their bats about, have a crack, score an acceptable 300 plus and surrender the two-game advantage?
No-one would've batted an eyelid in fact it was what most folk expected, almost assumed, would happen.
