After the current fault is fixed, more tests are required to further increase reliability and shake out other bugs that may be lurking. It is true for all strategic missiles, including A2, A3, Shaurya, AAD and PAD (including it final avatar that is not Prithvi based).
Shying away from rapid testing as these missiles enter IOC is serious disservice to India, IMHO intense flight testing regime is critical for these missile to be of real value to national defense.
