# 'conditions': [

#
# Note: foo_test.isolate is included and a source file. It is an inherent
# property of the .isolate format. This permits to define GYP variables but is
# a stricter format than GYP so isolate.py can read it.
#
# The generated .isolated file will be:
#   <(PRODUCT_DIR)/foo_test.isolated
