+# This script eases running the integration tests on the local machine.
+#
+# Configuration happens mostly through environment variables. In addition to
+# the already defined variables, the following are introduced for this script.
+#
+# - ICINGADB_TESTING_RUN_PREFIX
+#   Optional command to prefix the actual test run with, e.g., sudo.
+# - ICINGADB_TESTING_DATABASES
+#   Space-separated list of database types, defaults to "mysql pgsql".
+#
+# In addition to the environment variables, all arguments given to this script
+# are being passed to the go test call, e.g., -test.run to limit the tests.
+#
+# Example usage:
+# $ ICINGADB_TESTING_DATABASES=pgsql ./tests/run.sh -test.run TestHistory
