# Defines a target named $(my_target) for running robolectric tests.

# Running the tests is done in two stages: we first generate the test output to
# $(my_target_output), which is also added to the dist list, and store the
# return value of running the tests in $(my_target_retval). After that we
# process the output and return value as part of $(my_target). This is needed
# to make sure that we can install the test output even if the tests actually
# fail.

# Files in which to store the output and return value of the tests.
