Test cases implemented in phase 1:

Test Case	Script	Common for all vendors?
Case 1.1 Check platform information	tests/platform/test_platform_info.py	Yes
Case 1.3 Check SFP status and configure SFP	tests/platform/test_sfp.py	Yes
Case 1.4 Check xcvrd information in DB	tests/platform/test_xcvr_info_in_db.py	Yes
Case 2.1 Ensure that the hw-management service is running properly	tests/platform/mellanox/test_hw_management_service.py	No
Case 2.2 Check SFP using ethtool	tests/platform/mellanox/test_check_sfp_using_ethtool.py	No
Case 2.3 Check SYSFS	tests/platform/mellanox/test_check_sysfs.py	No
Case 2.4 Verify that /var/run/hw-management is mapped to docker pmon	tests/platform/mellanox/check_sysfs.py	No

How did you do it?

Implement the SONiC platform phase 1 test cases using the pytest-ansible framework and follow the design of PR #802

How did you verify/test it?

Tested on the mellanox platform

Any platform specific information?

This PR does not include platform specific test cases.

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

All current test topologies are supported:
[t0, t0-16, t0-56, t0-64, t0-64-32, t0-116, t1, t1-lag, t1-64-lag, ptf32, ptf64]

Looks good to me

tests/platform/test_platform_info.py

+    hostname = testbed['dut']
+    ans_host = ansible_host(ansible_adhoc, hostname)
+
+    logging.info("Check output of 'show platform summary'")


In general I suggest that commands name as well as expected error/OK message will be defined once (as a constant) and will be used by both log info as well as he command / message to use.
it is simpler in term changes might be introduced later on and code change will be done only once

Sure, updated in the new commit.

If i am not mistaken we also have low power mode option under sfputil. Should we add it as well?

Sure. Added SFP low power mode testing in the new commit.

@lguohan @liat-grozovik Any more comments?

The order of information output by command "show platform syseeprom" is not guranteed. This commit improve the method of comparing the content output by syseeprom plugin and the show command to avoid the failure caused by inconsistent output order. Signed-off-by: Xin Wang <xinw@mellanox.com>

Added a new commit fixing an issue of comparing syseeprom output from "show platform syseeprom" and platform plugin.
