No it doesn't. Imagine a bug in the reader that caused the data to be all 0.
To follow Lubomir in giving Christian more support, the 'clear-cut' "no it doesn't" seems (even to me :) a bit too harsh as Christian did admit that the test is not perfect and, statistically speaking (as he spoke of 'good indication'), he was not so far from truth (i.e. what is the probability of the reader reading all zeros and what of the reader and writer having a common bug...)... Knowing how much time I spent on io2 without writing a single test I can only imagine the time spent by Christian on writing all the other extensions and the tests for them. As it is becoming more and more apparent that even the amount of tests Christian did write is not enough to cover all the use cases that keep coming up I must again say that the most effective solution, at least when tests are concerned, would be for the reviewers to also join in constructively for example by writing (pseudo-code) tests that exercise their use cases... -- "What Huxley teaches is that in the age of advanced technology, spiritual devastation is more likely to come from an enemy with a smiling face than from one whose countenance exudes suspicion and hate."
