+"""Integration test for the ssh module.
+
+This module has two tests to verify if we can create ssh keys
+through the ``ssh`` module. The first test asserts that some keys
+were not created while the second one verifies if the expected
+keys were created.
+
+(This is ported from
+``tests/cloud_tests/testcases/modules/ssh_keys_generate.yaml``.)"""
