8.4.2. Testable Design Architecture

Try these first

1. 1.

   What is hierarchical testing?

   Hint

   Think about how you can manage a big task by dividing it into smaller tasks.

2. 2.

   Define observability in the context of testable design.

   Hint

   Consider how you check the internal workings of a machine.

3. 3.

   What is the main goal of hierarchical testing?

   • To reduce costs
   • To simplify complexity
   • To shorten product design time

   Hint

   Consider why it is important to handle one part at a time.

4. 4.

   True or False: Observability means internal signals cannot be viewed during testing.

   • True
   • False

   Hint

   Think about how a dashboard shows you internal car metrics.

5. 5.

   Consider a microcontroller used in robotics. Describe how you would implement hierarchical testing and ensure proper observability and controllability.

   Hint

   Think about the different functions of the robot and how you could isolate and test each one.

6. 6.

   You are tasked with designing an electronic device without focusing on testability. Discuss the potential defects that may arise and the long-term impacts on product longevity and customer satisfaction.

   Hint

   Consider the importance of quality assurance in maintaining customer trust.
