Testing is there to prove analysis, any data whatsoever that came out of this test is useful. They can only test for a very limited amount of loadcases and represent them as best they can. The tests are not completely accurate.
The results will be used to parallel the more comprehensive analysis and if they correlate the assumption that the rest of the analysis is good will be made.
Every test I have been involved in has had the conclusion of failure, you rarely get the opportunity to see how it breaks and test articles are not cheap.
I agree as above, this is no news. All part of aircraft development.
