New Connection

The new_connection boot method can be used to switch to a new connection. If the kernel and the device are both appropriately configured, a test can use a new connection to isolate test and kernel messages.

If the second connection uart0 is configured in the device dictionary, the connection can be created in a separate namespace.

- boot:
    namespace: isolation
    connection: uart0
    method: new_connection

The new_connection boot method must use a different namespace to all other actions in the test job. The test actions must pass this namespace label as the connection-namespace.

- test:
    namespace: hikey-oe
    connection-namespace: isolation
    definitions:
    - from: git
      repository: https://gitlab.com/lava/functional-tests.git
      path: posix/smoke-tests-basic.yaml
      name: smoke-tests
    timeout:
      minutes: 5
