rostest is not installed by jsk.rosbuild

I tried jsk.rosbuild as follows and got error in which rostest is not found.

install command

wget -q -O /tmp/jsk.rosbuild https://raw.github.com/jsk-ros-pkg/jsk_common/master/jsk.rosbuild
yes p | bash /tmp/jsk.rosbuild hydro --rtm

error message

CMake Error at /opt/ros/hydro/share/catkin/cmake/catkinConfig.cmake:72 (find_package):

  Set rostest_DIR to the directory containing a CMake configuration file for
  rostest.  The file will have one of the following names:
