A number of tests rely on SSH behavior but are not marked with SkipUnlessSSHKeysPresent(). This means that the tests will run and hang. This can be confusing for users because they may not know why the tests failed. Instead, we should be reporting on the known issue and skipping the test (hence why the helper Skip... function exists).
WARNING: Do not add tests in this directory
There are two types of end-to-end tests in Kubernetes:
Tests located in ${KUBE_ROOT}/test/e2e/common are shared by both Cluster
and Node E2E test jobs. Tests in ${KUBE_ROOT}/test/e2e_node are exclusively
owned by Node E2E. If you want to add a test, most likely than not, you want
to add the test to one of the two directories mentioned above. If you are
unsure, please check with the OWNER of the directory. This directory currently
contains misplaced and legacy tests; they will be cleaned up in the future.
