Recently I'm learning and evaluating LAVA to see if it can help us.

I saw next from https://validation.linaro.org/static/docs/v2/connections.html:

{% set connection_list = ['uart0', 'uart1'] %}
{% set connection_commands = {'uart0': 'telnet dispatcher01 7001', 'uart1': 'telnet dispatcher01 7002'} %}

I'm pretty confused by the 'uart0', 'uart1'. Should I explicitly specify something in my job to let some action to choose 'uart0' or 'uart1'? How does LAVA know at which time it should choose which uart?

Thanks,
