# Rules for running robolectric tests.
#
# Uses the following variables:
#
#   LOCAL_JAVA_LIBRARIES
#   LOCAL_STATIC_JAVA_LIBRARIES
#   LOCAL_ROBOTEST_FAILURE_FATAL
#   LOCAL_ROBOTEST_TIMEOUT
#   LOCAL_TEST_PACKAGE
#   ROBOTEST_FAILURE_FATAL
#   ROBOTEST_FILTER
#   ROBOTEST_RUN_INDIVIDUALLY
#
#
# If ROBOTEST_FAILURE_FATAL is set to true then failing tests will cause a
# build failure. Otherwise failures will be logged but ignored by make.
#
# If ROBOTEST_FILTER is set to a regex then only tests matching that pattern
# will be run. This currently only works at the class level.
#
# TODO: Switch to a JUnit runner which can support method-level test
# filtering and use that rather than grep to implement ROBOTEST_FILTER.
#
# If ROBOTEST_RUN_INDIVIDUALLY is set to true, each test class will be run by a
# different JVM, preventing any interaction between different tests. This is
# significantly slower than running all tests within the same JVM, but prevents
# unwanted interactions.
#
# Tests classes are found by looking for *Test.java files in
# LOCAL_PATH recursively.
