*
* i) Copy this file in your implementation directory

* ii) Rename OnboardCellularInterface everywhere in this file with your Class
* iii) Make an empty test application with the fork of mbed-os where your implementation resides
* iv) Create a json file in the root directory of your application and copy the contents of
* template_mbed_app.txt into it
* v) Now from the root of your application, enter this command:
* mbed test --compile-list
* Look for the name of of your test suite matching to the directory path
* vi) Run tests with the command:
* mbed test -n YOUR_TEST_SUITE_NAME
*
