+# This script simplifies run of kitchen tests for a given OS.
+# It must be executed from the root folder of the cookbook repo:
+# bash util/test-os.sh ec2 rhel8
+#
+# It searches for all the test suites defined in the functional cookbook and runs them sequentially.
+# The output will be saved into a `/tmp/kitchen-<os>-<date>` folder.
+# To run config tests is required to set a KITCHEN_${os}_AMI environment variable (e.g. KITCHEN_RHEL8_AMI)
+# or have a ParallelCluster AMI in the account.
