WebDF-GLS test of Elliott, Rothenberg, Stock (Econometrica,1996). The standard Dickey–Fuller test is essentially an OLS regression: in the simplest form, of the difference of the series (∆Xt) on the lagged level of the series (Xt−1). The “Augmented" Dickey-Fuller or ADF test adds a number of lagged differences to the specification.
