# The crosier_tests template is used to define crosier test targets in
# subdirectories. They should be in the dependency chain of the top-level
# chromeos_integration_tests target.
#
# crosier_tests behaves like source_set except that it supports (and expects) a
# "sources_metadata" variable that lists the yaml metadata files corresponding
# to the test sources. These files will be copied to the appropriate directory.
# See docs/testing/chromeos_integration/crosier_metadata.md for details.
