54 Model-Based Testing for Embedded Systems
• Data collection requirements. In addition to simple functional testing, the test framework
may also be called upon to gather data during a test run. This data may include the
response time of the SUT, analog signals to or from the SUT, or other data streams. You
will have to determine the data rates and the required precision of measurement. For very
large systems in which the test framework must be distributed, clock synchronization of
the test framework computers during data collection may become an important issue.
You may also have to reduce some of the collected data while a test is running, for
example, to determine pass/fail criteria for the test. If so, then supporting this data
reduction at run ...
