Chapter 4

1. What are the three main components that are part of nearly every test harness?
   • A test execution engine
   • A repository of tests
   • A test reporting mechanism
2. What are the advantages of using a test harness?
   • Automating testing, which then frees up developers to focus on other activities.
   • Performing regression testing, which can verify that recent changes haven't broken other pieces of code.
   • Increased code quality.
3. What are a few examples of faults that we would want a test harness to test for?
   • Non-responsive slave device
   • Invalid response
   • I2C bus errors
4. What are some of the architectures that a test harness can follow?
   • PC to embedded device
   • Embedded device monitor to embedded device target
   • Self-contained embedded device target and tester
5. What are the four operations that we need our module tests to perform?
   • Test setup
   • Test execution
   • Test cleanup
   • Test reporting...
