Approach

What is the motivation for this PR?

Currently, the test_stress_routes.py only runs on the following topologies: T0, T1, M0, MX. We wanted to support this test on T2 topology as well.

How did you do it?

Add T2 topology marker and make necessary changes to make the test pass on a T2 testbed.

How did you verify/test it?

I run the updated test on a T2 testbed and confirm it passed.

Any platform specific information?

Supported testbed topology if it's a new test case?

since you changed this funciton name, can you make sure all other places that were using get_crm_resources are fine?

[cyw233]

Hi @wenyiz2021, I did some search in the repo and found the following tests are using function get_crm_resources() (same function name from various places):

• arp/test_stress_arp.py
• crm/test_crm.py
• fdb/test_fdb_mac_move.py
• vxlan/test_vxlan_crm.py
• vxlan/test_vxlan_ecmp.py

Then I ran these tests and can confirm they are still working as expected.

Hi, @cyw233 , should we change other test scripts to support T2 as well?

[cyw233]

Hey @yutongzhang-microsoft, we have checked all the skipped tests on T2 and documented the ones that indeed need to be supported on T2. For example, this test_stress_routes should run on T2, while test_stress_arp should always be skipped on T2 because it's supposed to be run on T0 only.
This is the very beginning of the T2 test gap and we will make more test cases supported on T2, for example, supporting test_bfd.py on T2 is my very next ticket.

LGTM
every util has its own get_crm_resources
duthost has its own get_crm_resources
this get_crm_resource_status is specific to tests/stress/xx tests
