  The weighted forms of generalized survival and failure entropies of order
($\alpha,\beta$) are proposed and some properties are obtained. We further
propose the dynamic versions of weighted generalized survival and failures
entropies and obtained some properties and bounds. Characterization for
Rayleigh and power distributions are done by dynamic weighted generalized
entropies. We further consider the empirical versions of generalized weighted
survival and failure entropies and using the difference between theoretical and
empirical survival entropies a test for exponentiality is considered.
