It is possible to perform the first test flight even if the results were not that favourable (after all you are not going to come anywhere near limit load on your first test flight), but the authorities will almost certainly ask you to demonstrate that the flight envelope is being limited to mitigate the risk.
30th of november ZY997 successfully completed the static test with
the new wingbox design. The "2C test" exceeded the 100% load (2,5G) which
is required by the FAA for first flight.
They recreated the conditions that led to the delamination this summer.
The ultimate 150% load test is expected spring 2010.
