  Eclipsing binary systems with pulsating components offer a unique possibility
to accurately measure the most important parameters of pulsating stars, to
study their evolution, and to test the pulsation theory. I will show what we
can learn about the pulsating stars from the analysis of such systems and how
we can do it. Special attention will be paid to the mass, radius, p-factor, and
distance determination. Although the core of the method is based on the
observations of double-lined eclipsing spectroscopic binaries, with the help of
the pulsation theory, it is possible to measure absolute parameters for
single-lined binaries also.
