# This file contains tests for capturing of Thrift's isset data when the
# TStructDataStorage<T>::isset_indexes symbol is not present for every type.
#
# It is very dependent on the inner workings of CodeGen and Thrift so may be
# brittle.
#
# The test case "present" does not do anything special and so acts as a canary
# to determine whether other test failures are legitimate or due to some
# internal Thrift details changing.
