# Invokes generate_wrapper to create an executable script wrapping iOS'
# run.py with baked in arguments. Only takes effect when test entry in
# gn_isolate_map.pyl is updated to type="generated_script" with script
# set to the wrapper output path.
#
# Arguments:
#
# clones
#   (optional) number of ios simulator clones to execute tests on
#   in parallel
#
# data
#   (optional, default [ "//ios/build/bots/scripts/" ]) list of files or
#   directories required to run target
#
# data_deps
#   (optional) list of target non-linked labels
#
# deps
#   (optional) list of files or directories required to run target
#
# executable_args
#   (optional) a list of string arguments to pass to run.py
#
# retries
#   (optional, default 3) number of retry attempts
#
# shards
#   (optional) number of ios simulator clones to execute tests in parallel. not
#   the same as swarming shards. Only used if clones is not provided. Will be
#   deprecated.
#
# wrapper_output_name
#   (optional, default "run_${target_name}") name of the wrapper script
