  Pulsations and binarity are both common features of massive stars. The study
of pulsating massive stars in eclipsing binary systems hold great potential for
constraining stellar structure and evolution theory. However, prior to the
all-sky Transiting Exoplanet Survey Satellite (TESS) mission, few such systems
had been discovered or studied in detail. We have inspected the TESS light
curves of a large number of eclipsing binaries known to contain high-mass
stars, and compiled a list of 18 objects which show intrinsic variability. The
light curves were modelled both to determine the physical properties of the
systems, and to remove the effects of binarity in order to leave residual light
curves suitable for asteroseismic analysis. Precise mass and radius
measurements were obtained for delta Cir, CC Cas, SZ Cam, V436 Per and V539
Ara. We searched the residual light curves for pulsation signatures and, within
our sample of 18 objects, we find six definite and eight possible cases of beta
Cephei pulsation, seven cases of stochastic low-frequency (SLF) variability,
and eight instances of possible slowly pulsating B (SPB) star pulsation. The
large number of pulsating eclipsing systems we have identified makes
asteroseismology of high-mass stars in eclipsing binaries a feasible avenue to
constrain the interior physics of a large sample of massive stars for the first
time.
