High

Description of the test gap

Existing tests in the console and dut_console modules in sonic-mgmt cover basic console operation but there is no coverage for longer duration stability of console connections.

We need test cases to both read and write large blocks of characters into a serial console connection and ensure that the characters are transmitted successfully.

Affected Area

Serial Console (console/dut_console modules)

Impact of missing tests and proposed tests

Console connections are critical to access a SONiC device during early initialization as well as a last resort mechanism, so it is important for console connections to be stable at all times.
