Non-GSM Mobile Device Tool Test Assertions and Test Plan



Richard Ayers


As mobile devices proliferate, incorporating a host of integrated features and capabilities, their use can be seen everywhere in our world today. Mobile communication devices contain a wealth of sensitive and non-sensitive information. In the investigative community their use is not restricted to data recovery alone as in criminal cases, but also civil disputes and proceedings, and their aggregate use in research and criminal incident recreation continues to increase. Due to the exploding rate of growth in the production of new mobile devices appearing on the market each year is reason alone to pay attention to test measurement means and methods. The methods a tool uses to capture, process, and report data must incorporate a broad range of extensive capabilities to meet the demand as a robust data acquisition tool. In general, a forensic examination conducted on a mobile device is only a small subset of the larger field of digital forensics. Consequentially, tools possessing an exhaustive array of capabilities to acquire data from these portable mobile devices are relatively few in number. This paper defines assertions and test cases for mobile device applications capable of acquiring data from mobile devices operating over a Code Division Multiple Access (CDMA) network used to determine whether a specific tool meets the requirements producing measurable results. The assertions and test cases are derived from the requirements defined in the document entitled: Non- GSM Mobile Device Tool Specification. Test cases describe the combination of test parameters required to test each assertion. Test assertions are described as general statements or conditions that can be checked after a test is executed. Each assertion appears in one or more test cases consisting of a test protocol and the expected test results. The test protocol specifies detailed procedures for setting up the test, executing the test, and measuring the test results.
