  Cataclysmic variables (CVs) exhibit a plethora of variable phenomena many of
which require long, uninterrupted light curves to reveal themselves in detail.
The month long datasets provided by TESS are well suited for this purpose. TESS
has the additional advantage to have observed a huge number of stars, among
them many CVs. Here, a search for periodic variations in a sample of CVs of the
novalike and old novae subtypes is presented. In 10 of the 15 targets either
previously unseen positive or negative superhumps or unusual features in known
superhumps are identified. The TESS light curves demonstrate that the
occurrence of superhumps in these types of CVs is not an exception but quite
common. For 8 systems new or improved values for the orbital period are
measured. In TV Col the long-sought optical manifestation of the white dwarf
spin period is first seen in form of its orbital sideband. The mystery of
multiple photometric periods observed in CP Pup in the past is explained by
irregularly occurring anomalous states which are reflected in the light curve.
