Connected trucks provide vast amounts of valuable information in real time. Real-time access to data on fuel consumption, vehicle diagnostics and positioning, are vital in daily fleet operation. Based on the data, services can be developed and provided to customers that address specific needs like lowering fuel consumption and increasing uptime.
The Road Telematics Communicator (RTC) is responsible for keeping the vehicle connected and sending data from the vehicle to the offboard systems. The RTC uses data from different sources, for instance GNSS signals, wireless telecom signals and CAN signals.

The functionality of the RTC is verified by Scania with automatic test suites. There are regression and acceptance test suites that verify the functionality of the RTC. The test suites currently verify the functionality developed by Scania. Third party components are not part of the tests due to technical limitations in the test method, hence the RTC lacks automated tests for important features.

Due to the lack of complete verification in automated test suites, time consuming test on the road has to be performed and trouble reports from the field are difficult to analyse since certain conditions cannot be reproduced in a lab environment.
The goal of this thesis is to investigate and analyse how to best verify the third party components. Black Box and Exploratory tests have to be created that show the functionality of the third party components. The suggested test methods and tests should also be possible to add to the automatic test suites, so that the functionality of the RTC can be verified in a controlled environment.
First part of the assignment is to investigate how to use signal generators to give field-like input to the RTC and verify the behaviour of the GNSS module and the modem in the unit by examining the output from the third party components that receive the signals. Expected outcome would be documented test methods that describes how to test and how to maintain the test suites. The test methods should be possible to use for exploratory testing by designers when developing new features or debugging field errors.

Second part of the assignment is to investigate how to integrate the test methods in the Scania automatic test suites to extend the regression testing to include all components in the RTC.
