We consider various integrated lepton charge-energy asymmetries and azimuthal asymmetries as tests of [ital CP] violation in the process [ital e][sup [minus]][ital e+][r arrow][ital W][sup [minus]][ital W+]. These asymmetries are sensitive to different linear combinations of the [ital CP]-violating form factors in the three gauge boson [ital W][sup [minus]][ital W+] production vertex, and can distinguish dispersive and absorptive parts of the form factors. It makes use of purely hadronic and purely leptonic modes of [ital W] decays as well as the mixed modes. The techniques of using the kinematics of jets or missing momentum to construct [ital CP]-odd observables are also employed. These [ital CP]-violating observables are illustrated in the generalized left-right model and the charged Higgs boson model.
