+# netdev tests
+This application tests the module `netdev`, it's base module `netdev_base` in
+particular.
+The tests can be automated by running
+
+```bash
+SENDER=0 make all flash && SENDER=1 make all flash && make test
+```
+
+The values of the network addresses, the channel, and the network ID can be
+configured by the environment variables
+
+* `NETDEV_TEST_RECEIVER` and `NETDEV_TEST_SENDER`,
+* `NETDEV_TEST_CHANNEL`,
+* `NETDEV_TEST_NID`
+
+You can set the role of the application by setting the `SENDER` variable to
+either 0 (application is receiver) or any other value (applictation is sender),
+but keep in mind, that both versions have to be flashed to to seperate devices
+(identified by `RECEIVER_PORT` and `SENDER_PORT` respectively) in order for
+`make test` to succeed.
