The tests test each module independently using the mock pipe, which implements the modem_pipe API, making it compatible with the modem modules. The modem_ppp module is slightly different from the others since it also interacts with the network stack. To acheive this, a mock implementation of the PPP L2 net iface has been implemented in the test suite for the modem_ppp. Signed-off-by: Bjarki Arge Andreasen <baa@trackunit.com>
