Is the Well Integrity Test Failing?

BP suspended the "top kill" operation for 16 hours - because, according to numerous experts, it was creating more damage to the well bore - without even telling the media, local officials or the public that it had delayed the effort until long afterwards.
BP also admitted - many days after it stopped the top kill attempt – (1) that BP had to stop because mud was leaking out below the seafloor, and (2) that capping the well from the top could blow out the whole well.
Similarly, it took more than 5 hours for BP to publicly announce the delay of the "well integrity test" after the decision to delay was made.
So BP doesn’t have a great track record of promptly informing us of what is happening.
But now that the well integrity test (background here and here) is underway, can we somehow tell if it’s working or not?
The government previously announced that the test would succeed if pressure in the well of 8,000-9,000 psi were observed for a sustained period. As Coast Guard admiral Thad Allen said:
We are looking for somewhere between 8,000 and 9,000 PSI inside the capping stack, which would indicate to us that the hydrocarbons are being forced up and the wellbores are being able to withstand that pressure. And that is good news.
If we are down around in the 4,000 to 5,000, 6,000 range that could potentially tell us that the hydrocarbons are being diverted someplace else, and we would have to try and assess the implications of that. And as you might imagine, there are gradations as you go up from 4,000 or 5,000 PSI up to 8,000 or 9,000. …
We will at some point try to get to 8,000 or 9,000 and sustain that for some period of time, and these will be done basically, as I said — if we have a very low pressure reading, we

Well Integrity Test Has Now Started, But Oil Industry Experts Ask “What the Hell Are They Doing?”

Well Integrity Test Has Now Started, But Oil Industry Experts Ask "What the Hell Are They Doing?"

Admiral Thad Allen just announced that the well integrity test will commence tonight. For background on what this means, see this and this.
As I noted yesterday, BP suspended the "top kill" operation for 16 hours – because, according to numerous experts, it was creating more damage to the well bore – without even telling the media, local officials or the public that it had even delayed the effort until long afterwards.
Similarly, it took more than 5 hours for BP to publicly announce the delay of the well integrity test after the decision to delay was made.
Oil industry expert Rob Cavner – who has been right about virtually everything so far, previously explaining that there is damage in the oil well beneath the seafloor, and that BP has to let the oil spill keep on gushing to avoid further damage to the well bore until the well can be killed with relief wells (subsequently confirmed by BP) – now says that he is worried that the well integrity test could further damage the well bore and could blow out the entire well:
And as Cavner points out today, the government and BP are fooling around instead of killing off this monster once and for all with the relief wells:
What? Well integrity test? I’ve looked back through all of my notes, blog entries, and reviewed BP’s and the Unified Command’s communications. I’ve even done multiple internet searches, and found the first mention of a "well integrity test" related to BP on this past Sunday, July 11. Certainly I could have missed something, but I don’t recall even a single mention of what I consider to be probably the most significant (and risky) operation BP has conducted since the much hailed, and utterly failed, top kill procedure that kept the masses enthralled during the Memorial Day weekend.

This morning, we learned that, even thought the stack has now been set for 3 days, they actually haven’t hooked up the two new valves. He also announced that yesterday, they pulled all of the ships off site to run
