# Allows testing of a locally publish uber jar with against an
# arbitrary Java version using the JUnit console test runner (which
# will be downloaded if not present).
#
# First build and locally publish an uber jar, e.g. using
# publishLocalUber.sh
#
# Second set up the version of Java to be used for testing, e.g. by
# setting JAVA_HOME
#
# Then run this script which will download the JUnit runner if needed,
# build the Conscrypt testJar and then run the tests.
#
# Essentially these are the same steps as the final test matrix in the
# Github CI script.
