Let's drop the leading IETF or Infix prefixes from tests. Initially the idea was to mimnic the YANG models, but it's difficult to navigate and does not provide any real benefit to developers or end-users. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
=== Container Upgrade
ifdef::topdoc[:imagesdir: {topdoc}../../test/case/containers/upgrade]
==== Description
Verify container upgrade functionality by testing the optimization
that skips recreation when the container configuration hasn't changed.
This test uses two versions of curios-httpd (24.05.0 and 24.11.0) served
over HTTP with :latest tag. The test verifies that:
1. Container starts successfully from the :latest image
2. When the :latest tag points to a new version, upgrade is triggered
3. The container runs the new version after upgrade
==== Topology

==== Sequence
. Set up topology and attach to target DUT
. Detect target architecture
. Set up isolated network and file server
. Create symlink for curios-httpd:latest -> 24.05.0
. Create container 'web' from curios-httpd:latest (24.05.0)
. Verify container 'web' has started with version 24.05.0
. Update symlink to point to curios-httpd:24.11.0
. Trigger container upgrade by calling upgrade action
. Wait for container 'web' to complete uprgade
. Verify container 'web' is running new version 24.11.0
. Verify old image was pruned and disk usage is reasonable
