Three-body scattering is described in the framework of exact Faddeev-type integral equations that are solved numerically using momentum-space partial-wave basis. The Coulomb interaction between charged particles is included using the screening and renormalization method. The technique is applied to three-nucleon scattering and to elastic, transfer, and breakup reactions in three-body-like nuclear systems. Examples are deuteron scattering on stable nuclei ^{4}He, ^{10}Be, ^{12}C, ^{14}C, ^{16}O, ^{40}Ca, and ^{58}Ni and proton scattering on weakly bound two-body systems such as ^{11}Be, ^{13}C, ^{15}C, and ^{17}O. These calculations allow us to evaluate the accuracy of traditional approximate nuclear reaction approaches like the continuum-discretized coupled-channels (CDCC) method but also to test novel dynamical models such as nonlocal optical potentials. Finally, the technique is extended to low-energy four-nucleon elastic and transfer reactions.
