Existing tests relied on manually captured system data from various
points in Infix's history, making them hard to extend as we add new
features.
Move to a new model where we:
To update a unit test:
1. Use Infamy tests to setup a DUT in a known state
2. Use yanger's wrapper mode to capture the system state needed to
produce operational data for a set of YANG models
3. Use cli-pretty to create the expected output for a set of show
commands
When running unit tests, we can then use the captured data to verify
that yanger and cli-pretty works as expected without the need for a
running Infix system - just like before. The difference is that it is
now much easier to capture a new snapshot when the system evolves.
Ensure that all flavors of GRE tunnels can be configured. In addition
to the increased test coverage, it will also be useful as a basis for
collecting representative system state for CLI testing.
Ensure that VLANs can be configured on VLAN filtering bridges. In
addition to the increased test coverage, it will also be useful as a
basis for collecting representative system state for CLI testing.
This is just a first step to add VXLAN tunnels, much more remains.
Implemented right now is as GRE, local, remote and a VNI.
Also refactor gre_basic and gre_bridged to generic tunnel tests,
the same test now tests VXLAN as well.
The suite can also contain meta data for the test specification,
One meta data that is implemented is title, which is used when the
same test code is used twice with parameters.
Also if a test case should not be present in the test specification
for some case. You can add specification: False as meta data.
The yanger source grown significantly, code is disorganized, the
namespace is all over the place, etc.
Take a stab at remedying the situation by splitting out the individual
YANG models in separate Python modules, starting with ietf-system.
Basic support GRE and GRETAP tunnels both for IPv4 and IPv6.
Limited support right now, only possible to configure local
ip address and remote ip address.
* Use new cleanup in infamy to ensure the boot order gets restored
* Use new boot order in operational and use RPC to set boot order
to remove all SSH commands.
Make sure that we keep a record of the versions and boot source used
by all devices under test when running the full suite - in case we
ever suspect that there is a mismatch between the intended test image
and the actual one.
Since this test now needs to communicate with the devices, make sure
that we run the wait test first.
As it turns out, the setup with a 802.1D bridge in combination with
VLAN uppers stacked on the bridge ports is not possible to support
on mv88e6xxx ports.
Enable VLAN filtering to ensure proper isolation of the locally
terminated VLANs.
This will fail on a system running a vanilla kernel, where the dut's
ports are backed by mv88e6xxx, because:
1. The ports are attached to the same bridge, and are thus in the same
PVT group.
2. Creation of the VLAN uppers causes the DSA layer to add both ports
to the same VTU entry.
As a result, hardware behaves as if both ports had been configured as
tagged members of VLAN 10, instead of just terminating incoming
traffic locally.
Add this test to catch hardware which behaves in this way.
