Sometimes the test is trying it. And in this case, the "test" shows that some improvements are in order. I bet testing WAS done, but certain complexities that only later have become apparent were NOT apparent at the time of those preliminary tests.
I will, thus, refrain from being so hard on "them", hoping that this phase of the TEST shows the way to improvements.
Think about all the varieties of Coke that have emerged on the market, and remember the one that did not fair so well. The test was in putting it out there.
