Using number 7 here seems to be a recipe for long investigation when test fails. How can we make it clearer where this number came from and when test failed here, what to look for?
A comment will be a good start.

it comes from the buffers profile used for the test
I think it can be calculates (something like cat ... | grep "PROFILE" | wc -l)
I'll check and update this comment
| fvs = swsscommon.FieldValuePairs([("speed", speed)]) | ||
| # set same speed on all ports | ||
| for i in range(0, self.num_ports): | ||
| cfg_port_table.set("Ethernet%d" % (i*4), fvs) |

I suspect this change won't work for all devices.
It all depends on what is self.num_ports?
For instance, Arista7260CX3 has 64 physical ports, if self.num_ports is 64 for this device, then it is fine. However, when Arista7260CX3 is used for T0, it will have 56 out of 64 ports break into 2 50G ports, bring the total number of ports to 112 + 8 = 120. Most of these ports are Etherenet(x * 4) and Ethernet(x * 4 + 2) except the 8 100G ports. So if self.num_ports is 120 for this device, then the code here is incorrect.
Also, it appears that ASIC_STATE:SAI_OBJECT_TYPE_PORT also contains disabled ports. E.g. on the platform mentioned above, the number of entry is actually 123 (120 valid ports, 2 disabled ports, 1 cpu).
On the same mentioned platform, the asic port sequence doesn't directly map into Ethernet sequence. This is another assumption that would break, unfortunately.

It is designed to run on PLATFORM=vs

I see. Can you at least add a comment at beginning of this file?
Thanks,

the test does not pass, please check |

It will pass after VS docker is updated sonic-net/sonic-buildimage@ff8332f (it is part of buffers config PR sonic-net/sonic-buildimage#1250) |

Add support for hexists call.
Tested using below code snippet:
```
from swsscommon.swsscommon import SonicV2Connector
db = SonicV2Connector(host='127.0.0.1')
db.connect(db.COUNTERS_DB)
db.connect(db.ASIC_DB)
ex = int(db.hexists(db.COUNTERS_DB, "COUNTERS_PORT_NAME_MAP", "Ethernet0"))
if ex == 1:
print "Exists"
else:
print "Do not exists"
```

What I did
Added test for port speed change and PG buffer profile update
Why I did it
How I verified it
Ran the test and checked it passes
Details if related
should pass after
#417 and
sonic-net/sonic-buildimage#1250
are merged
