# Project tests
The project was classic for sensor management, for the treatment and for the main file.
However, the data measure storage (**storage_interface** class), use the EEPROM persistant memory with ordered dynamic storage structure leading to most of the project's complexity who need's to be test.
The [EEPROM_test_struct.cpp](EEPROM_test_struct.cpp) is made for this.

## storage_interface test
The file mainly contain unit test for **getter setter** function and **structure** functions.

**TODO** : Ideally add integration test for globally test project on simple use case.
